USE IN SPECIFIC POPULATIONS SECTION
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Pregnancy Category C
There are no adequate and well-controlled studies of modafinil in pregnant
women. Intrauterine growth restriction and spontaneous abortion have been
reported in association with modafinil (a mixture of R- and S-modafinil) and
armodafinil (the R-enantiomer of modafinil). Although the pharmacology of
modafinil is not identical to that of the sympathomimetic amines, it does
share some pharmacologic properties with this class. Certain of these drugs
have been associated with intrauterine growth restriction and spontaneous
abortions. Whether the cases reported with modafinil are drug-related is
unknown. In studies of modafinil and armodafinil conducted in rats (modafinil,
armodafinil) and rabbits (modafinil), developmental toxicity was observed at
clinically relevant plasma exposures. Modafinil tablets should be used during
pregnancy only if the potential benefit justifies the potential risk to the
fetus.
Modafinil (50, 100, or 200 mg/kg/day) administered orally to pregnant rats throughout organogenesis caused, in the absence of maternal toxicity, an increase in resorptions and an increased incidence of visceral and skeletal variations in the offspring at the highest dose tested. The higher no-effect dose for embryofetal developmental toxicity in rats (100 mg/kg/day) was associated with a plasma modafinil AUC less than that in humans at the recommended human dose (RHD) of modafinil tablets (200 mg/day). However, in a subsequent study of up to 480 mg/kg/day of modafinil, no adverse effects on embryofetal development were observed. Oral administration of armodafinil (60, 200, or 600 mg/kg/day) to pregnant rats throughout organogenesis resulted in increased incidences of fetal visceral and skeletal variations and decreased fetal body weight at the highest dose tested. The highest no-effect dose for embryofetal developmental toxicity in rats (200 mg/kg/day) was associated with a plasma armodafinil AUC less than that in humans at the RHD of modafinil tablets.
Modafinil administered orally to pregnant rabbits throughout organogenesis at doses of up to 100 mg/kg/day had no effect on embryofetal development; however, the doses used were too low to adequately assess the effects of modafinil on embryofetal development. In a subsequent developmental toxicity study evaluating doses of 45, 90, and 180 mg/kg/day in pregnant rabbits, the incidences of fetal structural alterations and embryofetal death were increased at the highest dose. The highest no-effect dose for developmental toxicity (100 mg/kg/day) was associated with a plasma modafinil AUC similar to that in humans at the RHD of modafinil tablets.
Modafinil administration to rats throughout gestation and lactation at oral doses of up to 200 mg/kg/day resulted in decreased viability in the offspring at doses greater than 20 mg/kg/day, a dose resulting in a plasma modafinil AUC less than that in humans at the RHD of modafinil tablets. No effects on postnatal developmental and neurobehavioral parameters were observed in surviving offspring.
8.3 Nursing Mothers
It is not known whether modafinil or its metabolites are excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when modafinil tablets are administered to a nursing woman.
8.4 Pediatric Use
Safety and effectiveness in pediatric patients have not been established. Modafinil tablets are not approved in this population for any indication.
Serious skin rashes, including erythema multiforme major (EMM) and Stevens- Johnson Syndrome (SJS) have been associated with modafinil use in pediatric patients [see Warnings and Precautions (5.1)].
In a controlled 6-week study, 165 pediatric patients (aged 5 to 17 years) with narcolepsy were treated with modafinil (n=123), or placebo (n=42). There were no statistically significant differences favoring modafinil over placebo in prolonging sleep latency as measured by MSLT, or in perceptions of sleepiness as determined by the clinical global impression-clinician scale (CGI-C).
In the controlled and open-label clinical studies, treatment emergent adverse reactions of the psychiatric and nervous system included Tourette’s syndrome, insomnia, hostility, increased cataplexy, increased hypnagogic hallucinations, and suicidal ideation. Transient leukopenia, which resolved without medical intervention, was also observed. In the controlled clinical study, 3 of 38 girls, ages 12 or older, treated with modafinil experienced dysmenorrhea compared to 0 of 10 girls who received placebo.
There were three 7 to 9 week, double-blind, placebo-controlled, parallel group studies in children and adolescents (aged 6 to 17 years) with Attention- Deficit Hyperactivity Disorder (ADHD). Two of the studies were flexible-dose studies (up to 425 mg/day), and the third was a fixed-dose study (340 mg/day for patients <30 kg and 425 mg/day for patients ≥30 kg). Although these studies showed statistically significant differences favoring modafinil over placebo in reducing ADHD symptoms as measured by the ADHD-RS (school version), there were 3 cases of serious rash including one case of possible SJS among 933 patients exposed to modafinil in this program. Modafinil is not approved for use in treating ADHD.
8.5 Geriatric Use
In clinical trials, experience in a limited number of modafinil-treated patients who were greater than 65 years of age showed an incidence of adverse reactions similar to other age groups. In elderly patients, elimination of modafinil and its metabolites may be reduced as a consequence of aging. Therefore, consideration should be given to the use of lower doses and close monitoring in this population [see Dosage and Administration (2.4) and Clinical Pharmacology (12.3)].
8.6 Hepatic Impairment
In patients with severe hepatic impairment, the dose of modafinil tablets should be reduced to one-half of that recommended for patients with normal hepatic function [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].
Pregnancy: Based on animal data, may cause fetal harm. (8.1)
OVERDOSAGE SECTION
10 OVERDOSAGE
In clinical trials, a total of 151 protocol-specified doses ranging from 1000 to 1600 mg/day (5 to 8 times the recommended daily dose of modafinil tablets) have been administered to 32 subjects, including 13 subjects who received doses of 1000 or 1200 mg/day for 7 to 21 consecutive days. In addition, several intentional acute overdoses occurred; the two largest being 4500 mg and 4000 mg taken by two subjects participating in foreign depression studies. None of these study subjects experienced any unexpected or life-threatening effects. Adverse reactions that were reported at these doses included excitation or agitation, insomnia, and slight or moderate elevations in hemodynamic parameters. Other observed high-dose effects in clinical studies have included anxiety, irritability, aggressiveness, confusion, nervousness, tremor, palpitations, sleep disturbances, nausea, diarrhea, and decreased prothrombin time.
From postmarketing experience, there have been reports of fatal overdoses involving modafinil alone or in combination with other drugs. Symptoms most often accompanying modafinil tablets overdose, alone or in combination with other drugs have included insomnia; central nervous system symptoms such as restlessness, disorientation, confusion, agitation, anxiety, excitation, and hallucination; digestive changes such as nausea and diarrhea; and cardiovascular changes such as tachycardia, bradycardia, hypertension, and chest pain.
Cases of accidental ingestion/overdose have been reported in children as young as 11 months of age. The highest reported accidental ingestion on a mg/kg basis occurred in a three-year-old boy who ingested 800 to 1000 mg (50 to 63 mg/kg) of modafinil tablets. The child remained stable. The symptoms associated with overdose in children were similar to those observed in adults.
No specific antidote exists for the toxic effects of a modafinil tablets overdose. Such overdoses should be managed with primarily supportive care, including cardiovascular monitoring.

Medication Guide available at www1.apotex.com/products/us
Read this Medication Guide before you start taking modafinil tablets and each time you get a refill. There may be new information. This information does not take the place of talking with your doctor about your medical condition or treatment.
What is the most important information I should know about modafinil tablets?
Modafinil tablets may cause serious side effects including a serious rash or a serious allergic reaction that may affect parts of your body such as your liver or blood cells. Any of these may need to be treated in a hospital and may be life-threatening.
Stop taking modafinil tablets and call your doctor right away or get emergency help if you have any of these symptoms:
- skin rash, hives, sores in your mouth, or your skin blisters and peels
- swelling of your face, eyes, lips, tongue, or throat
- trouble swallowing or breathing
- fever, shortness of breath, swelling of the legs, yellowing of the skin or whites of the eyes, or dark urine.
If you have a severe rash with modafinil tablets, stopping the medicine may not keep the rash from becoming life-threatening or causing you to be permanently disabled or disfigured.
Modafinil tablets are not approved for use in children for any medical
condition.
It is not known if modafinil tablets are safe or effective in children under
17 years of age.
What are modafinil tablets?
Modafinil tablets are a prescription medicine used to improve wakefulness in adults who are very sleepy due to one of the following diagnosed sleep disorders:
- narcolepsy
- obstructive sleep apnea (OSA). Modafinil tablets are used to treat excessive sleepiness, but not the obstruction or medical condition that is causing OSA. You should talk with your doctor about treatments for OSA before you start taking modafinil tablets and during treatment with modafinil tablets. Modafinil tablets do not take the place of treatments that your doctor has prescribed for OSA. It is important that you continue to use these treatments as prescribed by your doctor.
- shift work disorder (SWD)
Modafinil tablets will not cure these sleep disorders. Modafinil tablets may help the sleepiness caused by these conditions, but it may not stop all your sleepiness. Modafinil tablets do not take the place of getting enough sleep. Follow your doctor’s advice about good sleep habits and using other treatments.
Modafinil is a federally controlled substance (C-IV) because it can be abused or lead to dependence. Keep modafinil tablets in a safe place to prevent misuse and abuse. Selling or giving away modafinil tablets may harm others, and is against the law. Tell your doctor if you have ever abused or been dependent on alcohol, prescription medicines or street drugs. |
Who should not take modafinil tablets?
Do not take modafinil tablets if you:
- are allergic or developed a rash to modafinil or armodafinil (NUVIGIL® ) or any of the ingredients in modafinil tablets. See the end of this Medication Guide for a complete list of ingredients in modafinil tablets.
What should I tell my doctor before taking modafinil tablets?

**Tell your doctor about all the medicines you take,**including prescription and over-the-counter medicines, vitamins, and herbal supplements. Modafinil tablets and many other medicines can interact with each other, sometimes causing side effects. Modafinil tablets may affect the way other medicines work, and other medicines may affect how modafinil tablets works. Your dose of modafinil tablets or certain other medicines may need to be changed.
Especially, tell your doctor if you use or take:
- a hormonal birth control method, such as birth control pills, shots, implants, patches, vaginal rings, and intrauterine devices (IUDs). Hormonal birth control methods may not work while you take modafinil tablets. Women who use one of these methods of birth control may have a higher chance for getting pregnant while taking modafinil tablets, and for one month after stopping modafinil tablets. Talk to your doctor about birth control choices that are right for you while taking modafinil tablets.
Know the medicines you take. Keep a list of them and show it to your doctor and pharmacist when you get a new medicine. Your doctor or pharmacist will tell you if it is safe to take modafinil tablets and other medicines together. Do not start any new medicines with modafinil tablets unless your doctor has told you it is okay.
