- Instruction Composition
- The active substance is levonorgestrel.
The intrauterine delivery system contains 52 mg levonorgestrel. The initial release of levonorgestrel is approximately 20 micrograms per day and decreases progressively by about 70% after 8 years.
For the full list of excipients, see section 6.1.
- Instruction Dosage Form
- Intrauterine delivery system (IUS).
The product consists of levonorgestrel IUS (Figure 1b) and an inserter. The inserter is partially preloaded with the levonorgestrel IUS. The IUS consists of a T-shaped polyethylene frame (T-frame) with a drug reservoir around the vertical stem (Figure 1a). The drug reservoir is covered by an opaque membrane. The T-frame has an eyelet at one end of the vertical stem and two horizontal arms at the other end. A blue removal thread is attached to an eyelet at the end of the vertical stem of the T-frame. The T-frame of Benilexa One Handed contains barium sulphate, which makes it visible in X-ray examination.
The size of the T-body is 32 × 32 mm and the diameter of the insertion tube is 4.8 mm.
- Instruction Clinical Particulars
- 4.1 Therapeutic indications
Contraception.
Treatment of heavy menstrual bleeding. Benilexa One Handed may be particularly useful in women with heavy menstrual bleeding requiring (reversible) contraception.4.2 Posology and method of administration
Benilexa One Handed is effective for eight years in the indication contraception and has a demonstrated efficacy for three years for the indication heavy menstrual bleeding. Therefore, Benilexa One Handed should be removed or exchanged after 8 years of use, or earlier if heavy or bothersome menstrual bleeding returns.
If the user wishes to continue using the same method, a new system can be inserted at the same time, in which case no additional protection is required.
\*\*\*Starting treatment\*\*\*
In women of fertile age, Benilexa One Handed is inserted into the uterine cavity within seven days of the onset of menstruation. It can be replaced by a new system at any time of the cycle.
\*Post-partum insertion:\* To reduce the risk of perforation, postpartum insertions should be postponed until the uterus is fully involuted. Do not insert earlier than six weeks after delivery. If the patient is experiencing significant postpartum bleeding and/or pain then infection or other causes should be excluded before insertion. Benilexa One Handed can also be inserted immediately after the first trimester abortion.
\*Paediatric population\*
Benilexa One Handed has not been studied in patients below 16 years of age. Benilexa One Handed should not be used before menarche.
\*Hepatic impairment\*
Benilexa One Handed is contraindicated in patients with liver tumour or other acute or severe liver disease (see section 4.3).
\*\*\*Instructions for use and handling\*\*\*
Benilexa One Handed is supplied in a sterile pack which should not be opened until required for insertion. The exposed product should be handled with aseptic precautions. If the seal of the sterile package is broken, the product should be discarded (see section 6.6 for disposal instructions).
\*\*\*How to insert Benilexa One Handed\*\*\*
It is strongly recommended that Benilexa One Handed should only be inserted by physicians/health care professionals who are experienced in levonorgestrel IUS insertions and/or have undergone sufficient training for levonorgestrel IUS insertion.
In case of difficult insertion and/or exceptional pain or bleeding during or after insertion, please refer to section 4.4.
Benilexa One Handed is supplied sterile having been sterilised with ethylene oxide. Do not resterilise. For single use only. Do not use if the inner package is damaged or open. Insert before the last day of the month shown on the label.
Benilexa One Handed (figure 1a) is provided in a tray sealed with a peel-off lid, and is inserted with the provided inserter (figure 1b) into the uterine cavity by carefully following the insertion instructions.
The following insertion instruction will be provided in the box containing the IUS.
\*\*Please read the following instructions for use carefully as there may be some difference in the type of inserter device compared with other intrauterine devices (IUDs) you have used previously.\*\*

\*\*\*Conditions for use\*\*\*
1. In women of fertile age, Benilexa One Handed is inserted within seven days of the onset of menstruation. It can be replaced by a new system at any time of the cycle.
2. It is strongly recommended that Benilexa One Handed should only be inserted by physicians/health care professionals who have undergone sufficient training and have read carefully these instructions before Benilexa One Handed insertion.
3. Benilexa One Handed is supplied in a sterile packwhich should not be opened until required for insertion. The exposed product should be handled with aseptic precautions. Do not use if the inner package is damaged or open.
4. Determine the position (anteversion, retroversion) and size of the uterus by a gynaecological examination. Exclude pregnancy and contraindications.
5. Place a speculum, use appropriate antiseptic solution to clean the vagina and cervix.
6. Use cervical dilators if cervical stenosis is diagnosed. Do not force to overcome resistance. If cervical dilatation is required, consider using analgesics and/or a paracervical block.
7. Grasp the cervix with a Tenaculum forceps and apply a gentle traction in order to straighten alignment of the cervical canal and uterine cavity.
8. Determine the uterine depth by hysterometry. If uterine depth is < 5.5 cm discontinue the procedure.
\*\*\*Preparation for insertion\*\*\*
\*\*Step 1: Opening the sterile Benilexa One Handed packaging\*\*
- Remove the sealed tray containing Benilexa One Handed from the box.
- Inspect the sealed tray and do not use the product if the packaging, inserter or IUS is damaged.
- Lay the tray on a flat surface with the peel-off lid side up.
- Remove peel-off lid.
\*\*Step 2: Removing inserter from tray (Figure 3)\*\*
\*\*Step 3: Sliders completely forward for loading Benilexa One Handed (Figure 4)\*\*
\*\*Step 4: Load Benilexa One Handed into the inserter\*\*
- Ensure the arms of the IUS are horizontal (aligned to the horizontal plane of the handle and flange); adjust the rotation of the IUS as needed using the flat sterile surface of the tray.
- While maintaining \*\*\*\*forward pressure\*\*\*\* on the blue slider, gently pull the threads \*\*\*\*straight\*\*\*\* back to load Benilexa One Handed into the insertion tube. Ensure even tension is applied to both threads when pulling. Pull the threads upward or downward to lock the threads into the cleft at the bottom end of the handle (Figure 5); you must \*\*\*\*lock the threads\*\*\*\* in the cleft to prevent the IUS from moving out of the top of the insertion tube. Once the threads are locked in the cleft, \*\*\*\*stop holding the threads\*\*\*\*.
\*\*Figure 5: Locking the threads in cleft\*\*
- After the IUS is loaded, continue to sustain \*\*\*\*forward pressure\*\*\*\* on the BLUE slider to maintain a hemispherical dome with the tips of the IUS.
- When correctly loaded, the IUS is completely within the insertion tube with the tips of the arms forming a hemispherical dome at the top of the tube (Figure 6, Zoom 1).

\*Important information to consider during or after insertion:\*
- If you suspect the IUS is not in the correct position:
| | | |
| --- | --- | --- |
| | - | Check insertion with an ultrasound or other appropriate radiologic test. |
| | - | If incorrect insertion is suspected, remove Benilexa One Handed. Do not reinsert the same Benilexa One Handed IUS after removal. |
\*\*\*\*IMPORTANT!\*\*\*\*
In case of difficult insertion and/or exceptional pain or bleeding during or after insertion, physical examination and ultrasound should be performed immediately to exclude perforation of the uterine body or cervix. Physical examination alone (including checking of threads) may not be sufficient to exclude partial perforation. If necessary remove the system and insert a new, sterile system.
Please report any case of uterine perforation or insertion difficulties via:
Yellow Card Scheme; Website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
\*\*\*How to remove Benilexa One Handed\*\*\*
Benilexa One Handed is removed by gently pulling on the threads with forceps. The use of excessive force/sharp instruments during removal may cause breakage of the device. If the threads are not visible and the device is in the uterine cavity, it may be removed using a narrow tenaculum or intrauterine thread retriever. This may require dilatation of the cervical canal.
If pregnancy is not desired, the removal should be carried out during the menstruation in women of fertile age, provided that there appears to be a menstrual cycle. If the system is removed in the mid-cycle and the woman has had intercourse within a week, she is at a risk of pregnancy. To ensure continuous contraception a new system should be immediately inserted, or an alternative contraceptive method should have been initiated.
After removal of Benilexa One Handed, the system should be examined to ensure that it is intact and has been completely removed.. During difficult removals, single cases have been reported of the hormone cylinder sliding over the horizontal arms and hiding them together inside the cylinder. This situation does not require further intervention once completeness of the IUS has been ascertained. The knobs of the horizontal arms usually prevent complete detachment of the cylinder from the T-body.4.3 Contraindications
- Known or suspected pregnancy;
- Current or recurrent pelvic inflammatory disease;
- Lower genital tract infection;
- Postpartum endometritis;
- Infected abortion during the past three months;
- Cervicitis, cervical dysplasia;
- Suspected or confirmed uterine or cervical malignancy;
- Liver tumour or other acute or severe liver disease;
- Congenital or acquired abnormality of the uterus including fibroids if they distort the uterine cavity;
- Undiagnosed abnormal uterine bleeding;
- Conditions associated with increased susceptibility to infections;
- Current or suspected hormone dependent tumours such as breast cancer (see section 4.4);
- Acute malignancies affecting the blood or leukaemias except when in remission;
- Recent trophoblastic disease while hCG levels remain elevated;
- Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.4.4 Special warnings and precautions for use
\*\*\*Medical examination\*\*\*
Before insertion, a complete personal and family medical history should be taken. Physical examination should be guided by this and by the contraindications and warnings for use. Pulse and blood pressure should be measured and a bimanual pelvic examination performed to establish the orientation of the uterus. The patient should be re-examined six weeks after insertion and further examinations should be performed where clinically indicated and adapted to the individual woman rather than as routine procedure. Prior to insertion pregnancy should be excluded and genital infection should be successfully treated. Women should be advised that Benilexa One Handed does not protect against HIV (AIDS) and other sexually transmitted disease (please refer to the section below on pelvic infections).
Women should be encouraged to attend cervical and breast screening as appropriate for their age.
\*\*\*Conditions under which Benilexa One Handed can be used with caution\*\*\*
Benilexa One Handed may be used with caution after specialist consultation, or removal of the system should be considered, if any of the following conditions exist or arise for the first time during treatment:
- Migraine, focal migraine with asymmetrical visual loss or other symptoms indicating transient cerebral ischemia
- Unusually severe or unusually frequent headache
- Jaundice
- Marked increase of blood pressure
- Malignancies affecting the blood or leukaemias in remission
- Use of chronic corticosteroid therapy
- Past history of symptomatic functional ovarian cysts
- Active or previous severe arterial disease, such as stroke or myocardial infarction
- Severe or multiple risk factors for arterial disease
- Thrombotic arterial or any current embolic disease
- Acute venous thromboembolism
Benilexa One Handed may be used with caution in women who have congenital heart disease or valvular heart disease at risk of infective endocarditis.
Irregular bleedings may mask some symptoms and signs of endometrial polyps or cancer, and in these cases diagnostic measures have to be considered.
In general, women using Benilexa One Handed should be encouraged to stop smoking.
\*\*\*Insertion / removal warnings and precautions\*\*\*
\*General information:\* Insertion and removal may be associated with some pain and bleeding. In case of difficult insertion and/or exceptional pain or bleeding during or after insertion, physical examination and ultrasound should be performed immediately to exclude perforation of the uterine corpus or cervix (see also 'Perforation').
The procedure may precipitate fainting as a vasovagal reaction or a seizure in an epileptic patient. In the event of early signs of a vasovagal attack, insertion may need to be abandoned or the system removed. The woman should be kept supine, the head lowered and the legs elevated to the vertical position if necessary in order to restore cerebral blood flow. A clear airway must be maintained; an airway should always be at hand. Persistent bradycardia may be controlled with intravenous atropine. If oxygen is available it may be administered.
\*Perforation\*: Perforation of the uterine corpus or cervix may occur, most commonly during insertion, although it may not be detected until sometime later. This may be associated with severe pain and continued bleeding. If perforation is suspected the system should be removed as soon as possible; surgery may be required.
The incidence of perforation during or following Benilexa One Handed insertion in the clinical trial, which excluded breast-feeding women, was 0.1%.
In a large prospective comparative non-interventional cohort study in IUS/IUD users (N=61,448 women), the incidence of perforation was 1.3 (95% CI: 1.1-1.6) per 1,000 insertions in the entire study cohort; 1.4 (95% CI: 1.1-1.8) per 1,000 insertions in the cohort for another LNG-IUS and 1.1 (95% CI: 0.7-1.6) per 1,000 insertions in the copper IUD cohort.
The study showed that both breast-feeding at the time of insertion and insertion up to 36 weeks after giving birth were associated with an increased risk of perforation (see Table 1). These risk factors were independent of the type of IUS/IUD inserted.
Table 1: Incidence of perforation per 1,000 insertions for the entire study cohort, stratified by breastfeeding and time since delivery at insertion (parous women)
| | | |
| --- | --- | --- |
| | Breast-feeding at time of insertion | Not breast-feeding at time of insertion |
| Insertion ≤ 36 weeks after delivery | 5.6 (95% CI 3.9-7.9; n=6,047 insertions) | 1.7 (95% CI 0.8-3.1; n=5,927 insertions) |
| Insertion > 36 weeks after delivery | 1.6 (95% CI 0.0-9.1; n=608 insertions) | 0.7 (95% CI 0.5-1.1; n=41,910 insertions) |
Breast-feeding at the time of insertion and insertion up to 36 weeks after giving birth were confirmed as risk factors also in the subgroup that were followed up for 5 years.
The risk of perforation may be increased in postpartum insertions (see section 4.2), in lactating women and in women with a fixed retroverted uterus.
Re-examination after insertion should follow the guidance given above under the heading “Medical examination” above, which may be adapted as clinically indicated in women with risk factors for perforation.
\*Pelvic infection:\* In users of copper IUDs, the highest rate of pelvic infections occurs during the first month after insertion and decreases later.
Known risk factors for pelvic inflammatory disease are multiple sexual partners, frequent intercourse and young age. Pelvic infection may have serious consequences as it may impair fertility and increase the risk of ectopic pregnancy. As with other gynaecological or surgical procedures, severe infection or sepsis (including group A streptococcal sepsis) can occur following IUS insertion, although this is extremely rare.
For women using Benilexa One Handed with symptoms and signs suggestive of pelvic infection, bacteriological examinations are indicated and monitoring is recommended even with discrete symptoms, and appropriate antibiotics should be started. There is no need to remove Benilexa One Handed unless the symptoms fail to resolve within the following 72 hours or unless the woman wishes Benilexa One Handed to be removed. Benilexa One Handed must be removed if the woman experiences recurrent endometritis or pelvic infection, or if an acute infection is severe.
\*\*\*Complications leading to failure\*\*\*
\*Expulsion\*: In clinical trials with Benilexa One Handed in the indication contraception, the incidence of expulsion was low (<4% of insertions) and in the same range as reported for other IUDs and IUSs. Symptoms of partial or complete expulsion of Benilexa One Handed may include bleeding or pain. However, a system can be expelled from the uterine cavity without the woman noticing it leading to loss of contraceptive protection. As Benilexa One Handed decreases menstrual flow, increase of menstrual flow may be indicative of an expulsion.
Risk of expulsion is increased in
• Women with history of heavy menstrual bleeding (including women who use Benilexa One Handed for treatment of heavy menstrual bleeding)
• Women with greater than normal BMI at the time of insertion; this risk increases gradually with increasing BMI
Woman should be counselled on possible signs of expulsion and how to check the threads of Benilexa One Handed and advised to contact a healthcare professional if the threads cannot be felt. A barrier contraceptive (such as a condom) should be used until the location of Benilexa One Handed has been confirmed.
Partial expulsion may decrease the effectiveness of Benilexa One Handed.
A partially expelled Benilexa One Handed should be removed. A new system can be inserted at the time of removal, provided pregnancy has been excluded.
\*Lost threads\*: If the retrieval threads are not visible at the cervix on follow-up examination, first exclude pregnancy. The threads may have been drawn up into the uterus or cervical canal and may reappear during the next menstrual period. If they cannot be found, they may have broken off, the system may have been expelled, or rarely the device may be extra-uterine after having perforated the uterus. An ultrasound should be arranged to locate the device and alternative contraception should be advised in the meantime. If an ultrasound cannot locate the device and there is no evidence of expulsion, a plain abdominal X-ray should be performed to exclude an extra-uterine device.
\*\*\*Bleeding irregularities\*\*\*
\*Irregular bleeding:\* Benilexa One Handed usually achieves a significant reduction in menstrual blood loss within 3 to 6 months of treatment. Increased menstrual flow or unexpected bleeding may be indicative of expulsion. If menorrhagia persists then the woman should be re-examined. An assessment of the uterine cavity should be performed using ultrasound scan. An endometrial biopsy should also be considered.
\*\*\*Risk in pre-menopausal women\*\*\*
Because irregular bleeding/spotting may occur during the first months of therapy in pre-menopausal women, it is recommended to exclude endometrial pathology before insertion of Benilexa One Handed.
\*When to check for pregnancy in women of childbearing potential\*: The possibility of pregnancy should be considered if menstruation does not occur within six weeks of the onset of previous menstruation and expulsion should be excluded. A repeated pregnancy test is not necessary in amenorrhoeic subjects unless indicated by other symptoms. In women of fertile age, oligomenorrhoea and/or amenorrhea develops gradually in about 20% of the users. For details of amenorrhoea rates, see section 5.1.
\*Treatment review advice for menorrhagia\*: Benilexa One Handed usually achieves a significant reduction in menstrual blood loss within 3 to 6 months of treatment. If significant reduction in blood loss is not achieved in these timeframes, alternative treatments should be considered.
\*\*\*Other risks during use\*\*\*
\*Ectopic pregnancy\*: The absolute risk of ectopic pregnancy in users of levonorgestrel IUS is low. However, when a woman becomes pregnant with Benilexa One Handed in situ, the relative likelihood of ectopic pregnancy is increased. The possibility of ectopic pregnancy should be considered in the case of lower abdominal pain - especially in connection with missed periods or if an amenorrhoeic woman starts bleeding.
In the conducted clinical study, the overall incidence of ectopic pregnancy with Benilexa One Handed, was approximately 0.12 per 100 woman-years. Women considering Benilexa One Handed should be counselled on the signs, symptoms and risks of ectopic pregnancy. For women who become pregnant while using Benilexa One Handed, the possibility of an ectopic pregnancy must be considered and evaluated.
Women with a previous history of ectopic pregnancy, tubal surgery or pelvic infection carry an increased risk of ectopic pregnancy. The risk of ectopic pregnancy in women who have a history of ectopic pregnancy and use Benilexa One Handed is unknown. The possibility of ectopic pregnancy should be considered in the case of lower abdominal pain, especially in connection with missed periods or if an amenorrhoeic woman starts bleeding. Ectopic pregnancy may require surgery and may result in loss of fertility.
\*Ovarian cysts\*: Ovulatory cycles with follicular rupture usually occur in women of fertile age. Sometimes atresia of the follicle is delayed and folliculogenesis may continue. These enlarged follicles cannot be distinguished clinically from ovarian cysts. Most of these follicles are asymptomatic, although some may be accompanied by pelvic pain or dyspareunia.
In a clinical trial of Benilexa One Handed that enrolled 280 women presenting with heavy menstrual bleeding of which 141 received Benilexa One Handed, ovarian cyst (symptomatic and asymptomatic) was reported in 9.9% patients within 12 months of insertion. In a clinical trial of Benilexa One Handed which enrolled 1,751 subjects, symptomatic ovarian cysts occurred in approximately 4.5% of subjects using Benilexa One Handed, over 6 years and 0.3 % of subjects discontinued use of Benilexa One Handed because of an ovarian cyst.
In most cases, the ovarian cysts disappear spontaneously during two to three months observation. Should this not happen, continued ultrasound monitoring and other diagnostic/therapeutic measures are recommended. Rarely, surgical intervention may be required.
Depressed mood and depression are well-known undesirable effects of hormonal contraceptive use (see section 4.8). Depression can be serious and is a well-known risk factor for suicidal behaviour and suicide. Women should be advised to contact their physician in case of mood changes and depressive symptoms, including shortly after initiating the treatment.
\*Breast cancer\*
\*Risk in pre-menopausal women\*
A meta-analysis from 54 epidemiological studies reported that there is a slightly increased relative risk (RR=1.24) of having breast cancer diagnosed in women who are currently using combined oral contraceptives (COCs), mainly using oestrogen-progestogen preparations. The excess risk gradually disappears during the course of the 10 years after cessation of COC use. Because breast cancer is rare in women under 40 years of age, the excess number of breast cancer diagnoses in current and recent COC users is small in relation to the overall risk of breast cancer.
The risk of having breast cancer diagnosed in users of progestogen-only methods (POPs, implants and injectables), including Benilexa One Handed, is possibly of similar magnitude to that associated with COC. However, for progestogen-only contraceptive preparations, the evidence is based on much smaller populations of users and so is less conclusive than that for COCs.
\*\*\*General information\*\*\*
\*Glucose tolerance:\* Low-dose levonorgestrel may affect glucose tolerance and blood glucose concentrations should be monitored in diabetic users of Benilexa One Handed.
Post-coital contraception: Benilexa One Handed is not for use as a post-coital contraceptive.
The T-frame of Benilexa One Handed contains barium sulphate so that it can be seen on X-rays.4.5 Interaction with other medicinal products and other forms of interaction
The metabolism of progestogens may be increased by concomitant use of substances known to induce drug-metabolizing enzymes, specifically cytochrome P450 enzymes, such as anticonvulsants (e.g., phenobarbital, phenytoin, carbamazepine) and anti-infectives (e.g. griseofulvin\*\*,\*\* rifampicin, rifabutin, nevirapine, efavirenz). On the other hand, substances known to inhibit drug-metabolizing enzymes (e.g. itraconazole, ketoconazole) may increase serum concentrations of levonorgestrel. The influence of these drugs on the contraceptive efficacy of Benilexa One Handed is not known, but it is not believed to be of major importance due to the local mechanism of action.4.6 Fertility, pregnancy and lactation
\*\*Pregnancy\*\*
Benilexa One Handed is not to be used during an existing or suspected pregnancy. In case of an accidental pregnancy with Benilexa One Handed in situ (see section 5), ectopic pregnancy should be excluded (see section 4.4) and the system should be removed as soon as possible, as there is a high risk for pregnancy complications (abortion, preterm labor, infection and sepsis). Removal of Benilexa One Handed or probing of the uterus may also result in spontaneous abortion. Should these procedures not be possible or if the woman wishes to continue the pregnancy, the woman should be informed about these risks, and accordingly, such pregnancies should be closely monitored. The woman should be instructed to report all symptoms that suggest complications of the pregnancy, like cramping abdominal pain with fever.
\*Local exposure to levonorgestrel\*
In addition, an increased risk of virilising effects in a female foetus because of the intrauterine exposure to levonorgestrel cannot be excluded. There have been isolated cases of masculinisation of the external genitalia of the female foetus following local exposure to levonorgestrel during pregnancy with an LNG-IUS in place.
\*\*Breast-feeding\*\*
Levonorgestrel is excreted in very small quantities in breast milk after use in levonorgestrel IUS. Since no risk for the child is expected, breast feeding can be continued during use of Benilexa One Handed. Uterine bleeding has rarely been reported in women using a levonorgestrel IUS during lactation.
\*\*Fertility\*\*
The use of levonorgestrel IUS does not alter the course of female fertility after removal of the IUS.4.7 Effects on ability to drive and use machines
Benilexa One Handed has no known influence on the ability to drive or use machines.4.8 Undesirable effects
Undesirable effects are more common during the first months after the insertion, and subside during prolonged use.
Very common undesirable effects (occurring in more than 10% of users) include uterine/vaginal bleeding including spotting, oligomenorrhoea, amenorrhoea (see section 5.1) and benign ovarian cysts.
The frequency of benign ovarian cysts depends on the diagnostic method used, and in clinical trials enlarged follicles have been diagnosed in 12% of the subjects using a levonorgestrel IUS. Most of the follicles are asymptomatic and disappear within three months.

\\*This frequency is based on a large prospective comparative non-interventional cohort study in IUS/IUD users which showed that breast-feeding at the time of insertion and insertion up to 36 weeks after giving birth are independent risk factors for perforation (see section 4.4). In clinical trials with levonorgestrel IUS that excluded breastfeeding women the frequency of perforation was "rare".
\*Infections and infestations\*
Cases of sepsis (including group A streptococcal sepsis) have been reported following IUS insertion (see section 4.4).
\*Pregnancy, puerperium and perinatal conditions\*
When a woman becomes pregnant with Benilexa One Handed in situ, the relative risk of ectopic pregnancy is increased (see 'Special warnings and precautions for use' and 'Fertility, pregnancy and lactation').
\*Reproductive system and breast disorders\*
Cases of breast cancer have been reported in levonorgestrel IUS users (frequency unknown, see section 4.4).
The following adverse reactions have been reported in connection with the insertion or removal procedure of Benilexa One Handed: pain, bleeding, and insertion-related vasovagal reaction with dizziness or syncope (see section 4.4). The procedure may also precipitate a seizure in patients with epilepsy.
\*\*Reporting of suspected adverse reactions\*\*
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via:

Levonorgestrel is a progestogen used in gynaecology in various ways: as the progestogen component in oral contraceptives, in hormonal replacement therapy or alone for contraception in minipills and subdermal implants. Levonorgestrel can also be administered directly into the uterine cavity as an IUS. This allows a very low daily dosage, as the hormone is released directly into the target organ.
The contraceptive mechanism of action of the levonorgestrel IUS is based mainly on hormonal effects producing the following changes:
- Prevention of proliferation of the endometrium
- Thickening of the cervical mucus thus inhibiting the passage of sperm
- Suppression of ovulation in some women.
The physical presence of the system in the uterus would also be expected to make a minor contribution to its contraceptive effect.
In idiopathic menorrhagia, prevention of proliferation of the endometrium is the probable mechanism of action of levonorgestrel IUS in reducing blood loss.
\*\*Clinical Efficacy\*\*
\*Contraception Trial\*
When inserted according to the insertion instructions, Benilexa One Handed offers contraceptive protection which does not appear to vary by parity, race or body mass index. Contraceptive efficacy of Benilexa One Handed was investigated in a large clinical trial. The cumulative pregnancy rate calculated as the Pearl Index (PI) in women aged 16 to 35 years, at study entry was 0.15 (95% CI: 0.02, 0.55) at the end of year 1 and 0.18 (95% CI: 0.09, 0.33) at the end of year 8. The cumulative and year-by-year Pearl Indexes are shown in the table below:

19% of Benilexa One Handed users becoming amenorrhoeic by the end of the first year of use, 27% by the end of the second year of use, 36% by the end of the third year of use, 37% by the end of the fourth year of use, 40% by the end of the fifth year of use, 40% by the end of the sixth year of use, 39% at the end of the seventh year of use, and 39% at the end of the eighth year of use.
\*Heavy Menstrual Bleeding\*
In the clinical trial evaluating women with heavy menstrual bleeding (≥ 80 mL per menstrual cycle), Benilexa One Handed achieved a significant reduction in menstrual blood loss within 3 to 6 months of treatment. The volume of menstrual bleeding was decreased by 88% in women with heavy menstrual bleeding by the end of three months of use and 82% reduction was sustained for the duration of the study (12 months), with heavy menstrual bleeding caused by submucosal fibroids may respond less favourably. The effect was maintained during the extension phase of the study (up to 36 months). Reduced bleeding promotes an increase of blood haemoglobin in patients with heavy menstrual bleeding.5.2 Pharmacokinetic properties
The initial in vivo release rate of 20.4 micrograms/day levonorgestrel from Benilexa One Handed decreases to 17.7 micrograms/day during the first year, 15.3 micrograms/day during the second year, 13.3 micrograms/day during the third year, 11.5 micrograms/day during the fourth year, 10.0 micrograms/day during the fifth year, and 8.7 micrograms/day at sixth year, 7.5 micrograms/day during the seventh year, and 6.5 micrograms/day during the eighth year. Levonorgestrel is delivered directly into the uterine cavity with low plasma concentrations (252 ± 123 pg/mL 7 days after insertion and 88 ± 37 pg/mL after 8 years) resulting in only minor systemic effects.
The pharmacokinetics of levonorgestrel itself have been extensively investigated and reported in the literature. A half-life of 20 hours is considered the best estimate although some studies have reported values as short as 9 hours and others as long as 80 hours. Another important finding, although one in agreement with experience with other synthetic steroids, has been marked differences in metabolic clearance rates among individuals, even when administration was by the intravenous route. Levonorgestrel is extensively bound to proteins (mainly sex hormone binding globulin [SHBG]) and extensively metabolised to a large number of inactive metabolites.5.3 Preclinical safety data
Non-clinical data reveal no special hazard for humans other than the information already included in other sections of the SmPC. These data are based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity, carcinogenic potential and toxicity to reproduction and development.
Environmental risk assessment studies have shown that levonorgestrel may pose a risk for aquatic compartment.

Intrauterine delivery system (IUS).
The product consists of levonorgestrel IUS (Figure 1b) and an inserter. The inserter is partially preloaded with the levonorgestrel IUS. The IUS consists of a T-shaped polyethylene frame (T-frame) with a drug reservoir around the vertical stem (Figure 1a). The drug reservoir is covered by an opaque membrane. The T-frame has an eyelet at one end of the vertical stem and two horizontal arms at the other end. A blue removal thread is attached to an eyelet at the end of the vertical stem of the T-frame. The T-frame of Benilexa One Handed contains barium sulphate, which makes it visible in X-ray examination.
The size of the T-body is 32 × 32 mm and the diameter of the insertion tube is 4.8 mm.
## Clinical Particulars
4.1 Therapeutic indications
Contraception.
Treatment of heavy menstrual bleeding. Benilexa One Handed may be particularly useful in women with heavy menstrual bleeding requiring (reversible) contraception.4.2 Posology and method of administration
Benilexa One Handed is effective for eight years in the indication contraception and has a demonstrated efficacy for three years for the indication heavy menstrual bleeding. Therefore, Benilexa One Handed should be removed or exchanged after 8 years of use, or earlier if heavy or bothersome menstrual bleeding returns.
If the user wishes to continue using the same method, a new system can be inserted at the same time, in which case no additional protection is required.
\*\*\*Starting treatment\*\*\*
In women of fertile age, Benilexa One Handed is inserted into the uterine cavity within seven days of the onset of menstruation. It can be replaced by a new system at any time of the cycle.
\*Post-partum insertion:\* To reduce the risk of perforation, postpartum insertions should be postponed until the uterus is fully involuted. Do not insert earlier than six weeks after delivery. If the patient is experiencing significant postpartum bleeding and/or pain then infection or other causes should be excluded before insertion. Benilexa One Handed can also be inserted immediately after the first trimester abortion.
\*Paediatric population\*
Benilexa One Handed has not been studied in patients below 16 years of age. Benilexa One Handed should not be used before menarche.
\*Hepatic impairment\*
Benilexa One Handed is contraindicated in patients with liver tumour or other acute or severe liver disease (see section 4.3).
\*\*\*Instructions for use and handling\*\*\*
Benilexa One Handed is supplied in a sterile pack which should not be opened until required for insertion. The exposed product should be handled with aseptic precautions. If the seal of the sterile package is broken, the product should be discarded (see section 6.6 for disposal instructions).
\*\*\*How to insert Benilexa One Handed\*\*\*
It is strongly recommended that Benilexa One Handed should only be inserted by physicians/health care professionals who are experienced in levonorgestrel IUS insertions and/or have undergone sufficient training for levonorgestrel IUS insertion.
In case of difficult insertion and/or exceptional pain or bleeding during or after insertion, please refer to section 4.4.
Benilexa One Handed is supplied sterile having been sterilised with ethylene oxide. Do not resterilise. For single use only. Do not use if the inner package is damaged or open. Insert before the last day of the month shown on the label.
Benilexa One Handed (figure 1a) is provided in a tray sealed with a peel-off lid, and is inserted with the provided inserter (figure 1b) into the uterine cavity by carefully following the insertion instructions.
The following insertion instruction will be provided in the box containing the IUS.
\*\*Please read the following instructions for use carefully as there may be some difference in the type of inserter device compared with other intrauterine devices (IUDs) you have used previously.\*\*

\*\*\*Conditions for use\*\*\*
1. In women of fertile age, Benilexa One Handed is inserted within seven days of the onset of menstruation. It can be replaced by a new system at any time of the cycle.
2. It is strongly recommended that Benilexa One Handed should only be inserted by physicians/health care professionals who have undergone sufficient training and have read carefully these instructions before Benilexa One Handed insertion.
3. Benilexa One Handed is supplied in a sterile packwhich should not be opened until required for insertion. The exposed product should be handled with aseptic precautions. Do not use if the inner package is damaged or open.
4. Determine the position (anteversion, retroversion) and size of the uterus by a gynaecological examination. Exclude pregnancy and contraindications.
5. Place a speculum, use appropriate antiseptic solution to clean the vagina and cervix.
6. Use cervical dilators if cervical stenosis is diagnosed. Do not force to overcome resistance. If cervical dilatation is required, consider using analgesics and/or a paracervical block.
7. Grasp the cervix with a Tenaculum forceps and apply a gentle traction in order to straighten alignment of the cervical canal and uterine cavity.
8. Determine the uterine depth by hysterometry. If uterine depth is < 5.5 cm discontinue the procedure.
\*\*\*Preparation for insertion\*\*\*
\*\*Step 1: Opening the sterile Benilexa One Handed packaging\*\*
- Remove the sealed tray containing Benilexa One Handed from the box.
- Inspect the sealed tray and do not use the product if the packaging, inserter or IUS is damaged.
- Lay the tray on a flat surface with the peel-off lid side up.
- Remove peel-off lid.
\*\*Step 2: Removing inserter from tray (Figure 3)\*\*
\*\*Step 3: Sliders completely forward for loading Benilexa One Handed (Figure 4)\*\*
\*\*Step 4: Load Benilexa One Handed into the inserter\*\*
- Ensure the arms of the IUS are horizontal (aligned to the horizontal plane of the handle and flange); adjust the rotation of the IUS as needed using the flat sterile surface of the tray.
- While maintaining \*\*\*\*forward pressure\*\*\*\* on the blue slider, gently pull the threads \*\*\*\*straight\*\*\*\* back to load Benilexa One Handed into the insertion tube. Ensure even tension is applied to both threads when pulling. Pull the threads upward or downward to lock the threads into the cleft at the bottom end of the handle (Figure 5); you must \*\*\*\*lock the threads\*\*\*\* in the cleft to prevent the IUS from moving out of the top of the insertion tube. Once the threads are locked in the cleft, \*\*\*\*stop holding the threads\*\*\*\*.
\*\*Figure 5: Locking the threads in cleft\*\*
- After the IUS is loaded, continue to sustain \*\*\*\*forward pressure\*\*\*\* on the BLUE slider to maintain a hemispherical dome with the tips of the IUS.
- When correctly loaded, the IUS is completely within the insertion tube with the tips of the arms forming a hemispherical dome at the top of the tube (Figure 6, Zoom 1).

| | | |
| --- | --- | --- |
| | - | Check insertion with an ultrasound or other appropriate radiologic test. |
| | - | If incorrect insertion is suspected, remove Benilexa One Handed. Do not reinsert the same Benilexa One Handed IUS after removal. |
\*\*\*\*IMPORTANT!\*\*\*\*
In case of difficult insertion and/or exceptional pain or bleeding during or after insertion, physical examination and ultrasound should be performed immediately to exclude perforation of the uterine body or cervix. Physical examination alone (including checking of threads) may not be sufficient to exclude partial perforation. If necessary remove the system and insert a new, sterile system.
Please report any case of uterine perforation or insertion difficulties via:
Yellow Card Scheme; Website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
\*\*\*How to remove Benilexa One Handed\*\*\*
Benilexa One Handed is removed by gently pulling on the threads with forceps. The use of excessive force/sharp instruments during removal may cause breakage of the device. If the threads are not visible and the device is in the uterine cavity, it may be removed using a narrow tenaculum or intrauterine thread retriever. This may require dilatation of the cervical canal.
If pregnancy is not desired, the removal should be carried out during the menstruation in women of fertile age, provided that there appears to be a menstrual cycle. If the system is removed in the mid-cycle and the woman has had intercourse within a week, she is at a risk of pregnancy. To ensure continuous contraception a new system should be immediately inserted, or an alternative contraceptive method should have been initiated.
After removal of Benilexa One Handed, the system should be examined to ensure that it is intact and has been completely removed.. During difficult removals, single cases have been reported of the hormone cylinder sliding over the horizontal arms and hiding them together inside the cylinder. This situation does not require further intervention once completeness of the IUS has been ascertained. The knobs of the horizontal arms usually prevent complete detachment of the cylinder from the T-body.4.3 Contraindications
- Known or suspected pregnancy;
- Current or recurrent pelvic inflammatory disease;
- Lower genital tract infection;
- Postpartum endometritis;
- Infected abortion during the past three months;
- Cervicitis, cervical dysplasia;
- Suspected or confirmed uterine or cervical malignancy;
- Liver tumour or other acute or severe liver disease;
- Congenital or acquired abnormality of the uterus including fibroids if they distort the uterine cavity;
- Undiagnosed abnormal uterine bleeding;
- Conditions associated with increased susceptibility to infections;
- Current or suspected hormone dependent tumours such as breast cancer (see section 4.4);
- Acute malignancies affecting the blood or leukaemias except when in remission;
- Recent trophoblastic disease while hCG levels remain elevated;
- Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.4.4 Special warnings and precautions for use
\*\*\*Medical examination\*\*\*
Before insertion, a complete personal and family medical history should be taken. Physical examination should be guided by this and by the contraindications and warnings for use. Pulse and blood pressure should be measured and a bimanual pelvic examination performed to establish the orientation of the uterus. The patient should be re-examined six weeks after insertion and further examinations should be performed where clinically indicated and adapted to the individual woman rather than as routine procedure. Prior to insertion pregnancy should be excluded and genital infection should be successfully treated. Women should be advised that Benilexa One Handed does not protect against HIV (AIDS) and other sexually transmitted disease (please refer to the section below on pelvic infections).
Women should be encouraged to attend cervical and breast screening as appropriate for their age.
\*\*\*Conditions under which Benilexa One Handed can be used with caution\*\*\*
Benilexa One Handed may be used with caution after specialist consultation, or removal of the system should be considered, if any of the following conditions exist or arise for the first time during treatment:
- Migraine, focal migraine with asymmetrical visual loss or other symptoms indicating transient cerebral ischemia
- Unusually severe or unusually frequent headache
- Jaundice
- Marked increase of blood pressure
- Malignancies affecting the blood or leukaemias in remission
- Use of chronic corticosteroid therapy
- Past history of symptomatic functional ovarian cysts
- Active or previous severe arterial disease, such as stroke or myocardial infarction
- Severe or multiple risk factors for arterial disease
- Thrombotic arterial or any current embolic disease
- Acute venous thromboembolism
Benilexa One Handed may be used with caution in women who have congenital heart disease or valvular heart disease at risk of infective endocarditis.
Irregular bleedings may mask some symptoms and signs of endometrial polyps or cancer, and in these cases diagnostic measures have to be considered.
In general, women using Benilexa One Handed should be encouraged to stop smoking.
\*\*\*Insertion / removal warnings and precautions\*\*\*
\*General information:\* Insertion and removal may be associated with some pain and bleeding. In case of difficult insertion and/or exceptional pain or bleeding during or after insertion, physical examination and ultrasound should be performed immediately to exclude perforation of the uterine corpus or cervix (see also 'Perforation').
The procedure may precipitate fainting as a vasovagal reaction or a seizure in an epileptic patient. In the event of early signs of a vasovagal attack, insertion may need to be abandoned or the system removed. The woman should be kept supine, the head lowered and the legs elevated to the vertical position if necessary in order to restore cerebral blood flow. A clear airway must be maintained; an airway should always be at hand. Persistent bradycardia may be controlled with intravenous atropine. If oxygen is available it may be administered.
\*Perforation\*: Perforation of the uterine corpus or cervix may occur, most commonly during insertion, although it may not be detected until sometime later. This may be associated with severe pain and continued bleeding. If perforation is suspected the system should be removed as soon as possible; surgery may be required.
The incidence of perforation during or following Benilexa One Handed insertion in the clinical trial, which excluded breast-feeding women, was 0.1%.
In a large prospective comparative non-interventional cohort study in IUS/IUD users (N=61,448 women), the incidence of perforation was 1.3 (95% CI: 1.1-1.6) per 1,000 insertions in the entire study cohort; 1.4 (95% CI: 1.1-1.8) per 1,000 insertions in the cohort for another LNG-IUS and 1.1 (95% CI: 0.7-1.6) per 1,000 insertions in the copper IUD cohort.
The study showed that both breast-feeding at the time of insertion and insertion up to 36 weeks after giving birth were associated with an increased risk of perforation (see Table 1). These risk factors were independent of the type of IUS/IUD inserted.
Table 1: Incidence of perforation per 1,000 insertions for the entire study cohort, stratified by breastfeeding and time since delivery at insertion (parous women)
| | | |
| --- | --- | --- |
| | Breast-feeding at time of insertion | Not breast-feeding at time of insertion |
| Insertion ≤ 36 weeks after delivery | 5.6 (95% CI 3.9-7.9; n=6,047 insertions) | 1.7 (95% CI 0.8-3.1; n=5,927 insertions) |
| Insertion > 36 weeks after delivery | 1.6 (95% CI 0.0-9.1; n=608 insertions) | 0.7 (95% CI 0.5-1.1; n=41,910 insertions) |
Breast-feeding at the time of insertion and insertion up to 36 weeks after giving birth were confirmed as risk factors also in the subgroup that were followed up for 5 years.
The risk of perforation may be increased in postpartum insertions (see section 4.2), in lactating women and in women with a fixed retroverted uterus.
Re-examination after insertion should follow the guidance given above under the heading “Medical examination” above, which may be adapted as clinically indicated in women with risk factors for perforation.
\*Pelvic infection:\* In users of copper IUDs, the highest rate of pelvic infections occurs during the first month after insertion and decreases later.
Known risk factors for pelvic inflammatory disease are multiple sexual partners, frequent intercourse and young age. Pelvic infection may have serious consequences as it may impair fertility and increase the risk of ectopic pregnancy. As with other gynaecological or surgical procedures, severe infection or sepsis (including group A streptococcal sepsis) can occur following IUS insertion, although this is extremely rare.
For women using Benilexa One Handed with symptoms and signs suggestive of pelvic infection, bacteriological examinations are indicated and monitoring is recommended even with discrete symptoms, and appropriate antibiotics should be started. There is no need to remove Benilexa One Handed unless the symptoms fail to resolve within the following 72 hours or unless the woman wishes Benilexa One Handed to be removed. Benilexa One Handed must be removed if the woman experiences recurrent endometritis or pelvic infection, or if an acute infection is severe.
\*\*\*Complications leading to failure\*\*\*
\*Expulsion\*: In clinical trials with Benilexa One Handed in the indication contraception, the incidence of expulsion was low (<4% of insertions) and in the same range as reported for other IUDs and IUSs. Symptoms of partial or complete expulsion of Benilexa One Handed may include bleeding or pain. However, a system can be expelled from the uterine cavity without the woman noticing it leading to loss of contraceptive protection. As Benilexa One Handed decreases menstrual flow, increase of menstrual flow may be indicative of an expulsion.
Risk of expulsion is increased in
• Women with history of heavy menstrual bleeding (including women who use Benilexa One Handed for treatment of heavy menstrual bleeding)
• Women with greater than normal BMI at the time of insertion; this risk increases gradually with increasing BMI
Woman should be counselled on possible signs of expulsion and how to check the threads of Benilexa One Handed and advised to contact a healthcare professional if the threads cannot be felt. A barrier contraceptive (such as a condom) should be used until the location of Benilexa One Handed has been confirmed.
Partial expulsion may decrease the effectiveness of Benilexa One Handed.
A partially expelled Benilexa One Handed should be removed. A new system can be inserted at the time of removal, provided pregnancy has been excluded.
\*Lost threads\*: If the retrieval threads are not visible at the cervix on follow-up examination, first exclude pregnancy. The threads may have been drawn up into the uterus or cervical canal and may reappear during the next menstrual period. If they cannot be found, they may have broken off, the system may have been expelled, or rarely the device may be extra-uterine after having perforated the uterus. An ultrasound should be arranged to locate the device and alternative contraception should be advised in the meantime. If an ultrasound cannot locate the device and there is no evidence of expulsion, a plain abdominal X-ray should be performed to exclude an extra-uterine device.
\*\*\*Bleeding irregularities\*\*\*
\*Irregular bleeding:\* Benilexa One Handed usually achieves a significant reduction in menstrual blood loss within 3 to 6 months of treatment. Increased menstrual flow or unexpected bleeding may be indicative of expulsion. If menorrhagia persists then the woman should be re-examined. An assessment of the uterine cavity should be performed using ultrasound scan. An endometrial biopsy should also be considered.
\*\*\*Risk in pre-menopausal women\*\*\*
Because irregular bleeding/spotting may occur during the first months of therapy in pre-menopausal women, it is recommended to exclude endometrial pathology before insertion of Benilexa One Handed.
\*When to check for pregnancy in women of childbearing potential\*: The possibility of pregnancy should be considered if menstruation does not occur within six weeks of the onset of previous menstruation and expulsion should be excluded. A repeated pregnancy test is not necessary in amenorrhoeic subjects unless indicated by other symptoms. In women of fertile age, oligomenorrhoea and/or amenorrhea develops gradually in about 20% of the users. For details of amenorrhoea rates, see section 5.1.
\*Treatment review advice for menorrhagia\*: Benilexa One Handed usually achieves a significant reduction in menstrual blood loss within 3 to 6 months of treatment. If significant reduction in blood loss is not achieved in these timeframes, alternative treatments should be considered.
\*\*\*Other risks during use\*\*\*
\*Ectopic pregnancy\*: The absolute risk of ectopic pregnancy in users of levonorgestrel IUS is low. However, when a woman becomes pregnant with Benilexa One Handed in situ, the relative likelihood of ectopic pregnancy is increased. The possibility of ectopic pregnancy should be considered in the case of lower abdominal pain - especially in connection with missed periods or if an amenorrhoeic woman starts bleeding.
In the conducted clinical study, the overall incidence of ectopic pregnancy with Benilexa One Handed, was approximately 0.12 per 100 woman-years. Women considering Benilexa One Handed should be counselled on the signs, symptoms and risks of ectopic pregnancy. For women who become pregnant while using Benilexa One Handed, the possibility of an ectopic pregnancy must be considered and evaluated.
Women with a previous history of ectopic pregnancy, tubal surgery or pelvic infection carry an increased risk of ectopic pregnancy. The risk of ectopic pregnancy in women who have a history of ectopic pregnancy and use Benilexa One Handed is unknown. The possibility of ectopic pregnancy should be considered in the case of lower abdominal pain, especially in connection with missed periods or if an amenorrhoeic woman starts bleeding. Ectopic pregnancy may require surgery and may result in loss of fertility.
\*Ovarian cysts\*: Ovulatory cycles with follicular rupture usually occur in women of fertile age. Sometimes atresia of the follicle is delayed and folliculogenesis may continue. These enlarged follicles cannot be distinguished clinically from ovarian cysts. Most of these follicles are asymptomatic, although some may be accompanied by pelvic pain or dyspareunia.
In a clinical trial of Benilexa One Handed that enrolled 280 women presenting with heavy menstrual bleeding of which 141 received Benilexa One Handed, ovarian cyst (symptomatic and asymptomatic) was reported in 9.9% patients within 12 months of insertion. In a clinical trial of Benilexa One Handed which enrolled 1,751 subjects, symptomatic ovarian cysts occurred in approximately 4.5% of subjects using Benilexa One Handed, over 6 years and 0.3 % of subjects discontinued use of Benilexa One Handed because of an ovarian cyst.
In most cases, the ovarian cysts disappear spontaneously during two to three months observation. Should this not happen, continued ultrasound monitoring and other diagnostic/therapeutic measures are recommended. Rarely, surgical intervention may be required.
Depressed mood and depression are well-known undesirable effects of hormonal contraceptive use (see section 4.8). Depression can be serious and is a well-known risk factor for suicidal behaviour and suicide. Women should be advised to contact their physician in case of mood changes and depressive symptoms, including shortly after initiating the treatment.
\*Breast cancer\*
\*Risk in pre-menopausal women\*
A meta-analysis from 54 epidemiological studies reported that there is a slightly increased relative risk (RR=1.24) of having breast cancer diagnosed in women who are currently using combined oral contraceptives (COCs), mainly using oestrogen-progestogen preparations. The excess risk gradually disappears during the course of the 10 years after cessation of COC use. Because breast cancer is rare in women under 40 years of age, the excess number of breast cancer diagnoses in current and recent COC users is small in relation to the overall risk of breast cancer.
The risk of having breast cancer diagnosed in users of progestogen-only methods (POPs, implants and injectables), including Benilexa One Handed, is possibly of similar magnitude to that associated with COC. However, for progestogen-only contraceptive preparations, the evidence is based on much smaller populations of users and so is less conclusive than that for COCs.
\*\*\*General information\*\*\*
\*Glucose tolerance:\* Low-dose levonorgestrel may affect glucose tolerance and blood glucose concentrations should be monitored in diabetic users of Benilexa One Handed.
Post-coital contraception: Benilexa One Handed is not for use as a post-coital contraceptive.
The T-frame of Benilexa One Handed contains barium sulphate so that it can be seen on X-rays.4.5 Interaction with other medicinal products and other forms of interaction
The metabolism of progestogens may be increased by concomitant use of substances known to induce drug-metabolizing enzymes, specifically cytochrome P450 enzymes, such as anticonvulsants (e.g., phenobarbital, phenytoin, carbamazepine) and anti-infectives (e.g. griseofulvin\*\*,\*\* rifampicin, rifabutin, nevirapine, efavirenz). On the other hand, substances known to inhibit drug-metabolizing enzymes (e.g. itraconazole, ketoconazole) may increase serum concentrations of levonorgestrel. The influence of these drugs on the contraceptive efficacy of Benilexa One Handed is not known, but it is not believed to be of major importance due to the local mechanism of action.4.6 Fertility, pregnancy and lactation
\*\*Pregnancy\*\*
Benilexa One Handed is not to be used during an existing or suspected pregnancy. In case of an accidental pregnancy with Benilexa One Handed in situ (see section 5), ectopic pregnancy should be excluded (see section 4.4) and the system should be removed as soon as possible, as there is a high risk for pregnancy complications (abortion, preterm labor, infection and sepsis). Removal of Benilexa One Handed or probing of the uterus may also result in spontaneous abortion. Should these procedures not be possible or if the woman wishes to continue the pregnancy, the woman should be informed about these risks, and accordingly, such pregnancies should be closely monitored. The woman should be instructed to report all symptoms that suggest complications of the pregnancy, like cramping abdominal pain with fever.
\*Local exposure to levonorgestrel\*
In addition, an increased risk of virilising effects in a female foetus because of the intrauterine exposure to levonorgestrel cannot be excluded. There have been isolated cases of masculinisation of the external genitalia of the female foetus following local exposure to levonorgestrel during pregnancy with an LNG-IUS in place.
\*\*Breast-feeding\*\*
Levonorgestrel is excreted in very small quantities in breast milk after use in levonorgestrel IUS. Since no risk for the child is expected, breast feeding can be continued during use of Benilexa One Handed. Uterine bleeding has rarely been reported in women using a levonorgestrel IUS during lactation.
\*\*Fertility\*\*
The use of levonorgestrel IUS does not alter the course of female fertility after removal of the IUS.4.7 Effects on ability to drive and use machines
Benilexa One Handed has no known influence on the ability to drive or use machines.4.8 Undesirable effects
Undesirable effects are more common during the first months after the insertion, and subside during prolonged use.
Very common undesirable effects (occurring in more than 10% of users) include uterine/vaginal bleeding including spotting, oligomenorrhoea, amenorrhoea (see section 5.1) and benign ovarian cysts.
The frequency of benign ovarian cysts depends on the diagnostic method used, and in clinical trials enlarged follicles have been diagnosed in 12% of the subjects using a levonorgestrel IUS. Most of the follicles are asymptomatic and disappear within three months.
The table 2. below reports adverse reactions by MedDRA system organ class (MedDRA SOCs). The frequencies are based on clinical trial data.

\\*This frequency is based on a large prospective comparative non-interventional cohort study in IUS/IUD users which showed that breast-feeding at the time of insertion and insertion up to 36 weeks after giving birth are independent risk factors for perforation (see section 4.4). In clinical trials with levonorgestrel IUS that excluded breastfeeding women the frequency of perforation was "rare".
\*Infections and infestations\*
Cases of sepsis (including group A streptococcal sepsis) have been reported following IUS insertion (see section 4.4).
\*Pregnancy, puerperium and perinatal conditions\*
When a woman becomes pregnant with Benilexa One Handed in situ, the relative risk of ectopic pregnancy is increased (see 'Special warnings and precautions for use' and 'Fertility, pregnancy and lactation').
\*Reproductive system and breast disorders\*
Cases of breast cancer have been reported in levonorgestrel IUS users (frequency unknown, see section 4.4).
The following adverse reactions have been reported in connection with the insertion or removal procedure of Benilexa One Handed: pain, bleeding, and insertion-related vasovagal reaction with dizziness or syncope (see section 4.4). The procedure may also precipitate a seizure in patients with epilepsy.
\*\*Reporting of suspected adverse reactions\*\*
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via:

## Pharmacological Properties
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Intrauterine contraceptives, plastic IUD with progestogen ATC code: G02BA03
Levonorgestrel is a progestogen used in gynaecology in various ways: as the progestogen component in oral contraceptives, in hormonal replacement therapy or alone for contraception in minipills and subdermal implants. Levonorgestrel can also be administered directly into the uterine cavity as an IUS. This allows a very low daily dosage, as the hormone is released directly into the target organ.
The contraceptive mechanism of action of the levonorgestrel IUS is based mainly on hormonal effects producing the following changes:
- Prevention of proliferation of the endometrium
- Thickening of the cervical mucus thus inhibiting the passage of sperm
- Suppression of ovulation in some women.
The physical presence of the system in the uterus would also be expected to make a minor contribution to its contraceptive effect.
In idiopathic menorrhagia, prevention of proliferation of the endometrium is the probable mechanism of action of levonorgestrel IUS in reducing blood loss.
\*\*Clinical Efficacy\*\*
\*Contraception Trial\*
When inserted according to the insertion instructions, Benilexa One Handed offers contraceptive protection which does not appear to vary by parity, race or body mass index. Contraceptive efficacy of Benilexa One Handed was investigated in a large clinical trial. The cumulative pregnancy rate calculated as the Pearl Index (PI) in women aged 16 to 35 years, at study entry was 0.15 (95% CI: 0.02, 0.55) at the end of year 1 and 0.18 (95% CI: 0.09, 0.33) at the end of year 8. The cumulative and year-by-year Pearl Indexes are shown in the table below:

Supportive analyses for Year 7 and Year 8 of the year-by-year non-cumulative PI excluding 28-day cycles during which a subject reported one or more days of use of another birth control method from the denominator and using a subset of the efficacy population limited to subjects age 35 or less at the beginning of the year had a total of 3,873 × 28-day cycles with a PI of 0.67 (0.08, 2.42) and a total of 2,677 × 28-day cycles with a PI of 0.00 (0.00, 1.79), respectively.
19% of Benilexa One Handed users becoming amenorrhoeic by the end of the first year of use, 27% by the end of the second year of use, 36% by the end of the third year of use, 37% by the end of the fourth year of use, 40% by the end of the fifth year of use, 40% by the end of the sixth year of use, 39% at the end of the seventh year of use, and 39% at the end of the eighth year of use.
\*Heavy Menstrual Bleeding\*
In the clinical trial evaluating women with heavy menstrual bleeding (≥ 80 mL per menstrual cycle), Benilexa One Handed achieved a significant reduction in menstrual blood loss within 3 to 6 months of treatment. The volume of menstrual bleeding was decreased by 88% in women with heavy menstrual bleeding by the end of three months of use and 82% reduction was sustained for the duration of the study (12 months), with heavy menstrual bleeding caused by submucosal fibroids may respond less favourably. The effect was maintained during the extension phase of the study (up to 36 months). Reduced bleeding promotes an increase of blood haemoglobin in patients with heavy menstrual bleeding.5.2 Pharmacokinetic properties
The initial in vivo release rate of 20.4 micrograms/day levonorgestrel from Benilexa One Handed decreases to 17.7 micrograms/day during the first year, 15.3 micrograms/day during the second year, 13.3 micrograms/day during the third year, 11.5 micrograms/day during the fourth year, 10.0 micrograms/day during the fifth year, and 8.7 micrograms/day at sixth year, 7.5 micrograms/day during the seventh year, and 6.5 micrograms/day during the eighth year. Levonorgestrel is delivered directly into the uterine cavity with low plasma concentrations (252 ± 123 pg/mL 7 days after insertion and 88 ± 37 pg/mL after 8 years) resulting in only minor systemic effects.
The pharmacokinetics of levonorgestrel itself have been extensively investigated and reported in the literature. A half-life of 20 hours is considered the best estimate although some studies have reported values as short as 9 hours and others as long as 80 hours. Another important finding, although one in agreement with experience with other synthetic steroids, has been marked differences in metabolic clearance rates among individuals, even when administration was by the intravenous route. Levonorgestrel is extensively bound to proteins (mainly sex hormone binding globulin [SHBG]) and extensively metabolised to a large number of inactive metabolites.5.3 Preclinical safety data
Non-clinical data reveal no special hazard for humans other than the information already included in other sections of the SmPC. These data are based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity, carcinogenic potential and toxicity to reproduction and development.
Environmental risk assessment studies have shown that levonorgestrel may pose a risk for aquatic compartment.
