- Dosage
- **Recommended Dosage:**
_**Non-small cell lung cancer (NSCLC)**_
_Monotherapy_
The recommended dose of gemcitabine is 1,000 mg/m2, given by 30-minute intravenous infusion. This should be repeated once weekly for 3 weeks, followed by a 1-week rest period. This 4-week cycle is then repeated. Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient.
_Combination use_
Gemcitabine in combination with cisplatin has been investigated using two dosing regimen. One regimen used a 3-week schedule and the other used a 4-week schedule.
The 3-week schedule used gemcitabine 1,250 mg/m2, given by 30-minute intravenous infusion, on days 1 and 8 of each 21-day cycle. Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient.
The 4-week schedule used gemcitabine 1,000 mg/m2, given by 30-minute intravenous infusion, on days 1, 8, and 15 of each 28-day cycle. Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient.
Cisplatin has been used at doses between 75–100 mg/m2 once every 3 or 4 weeks.
_**Pancreatic cancer**_
_Monotherapy_
The recommended dose of gemcitabine is 1,000 mg/m2, given by 30-minute intravenous infusion. This should be repeated once weekly for up to 7 weeks, followed by a week of rest. Subsequent cycles should consist of injections once weekly for 3 consecutive weeks out of every 4 weeks. Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient.
_**Bladder cancer**_
_Combination use_
The recommended dose for gemcitabine is 1,000 mg/m2, given by 30-minute infusion. The dose should be given on days 1, 8, and 15 of each 28-day cycle in combination with cisplatin. Cisplatin is given at a recommended dose of 70 mg/m2 on day 1 following gemcitabine or day 2 of each 28-day cycle. This 4-week cycle is then repeated. Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient. More myelosuppression when cisplatin was used in doses of 100 mg/m2.
_**Breast cancer**_
_Combination use_
Gemcitabine in combination with paclitaxel is recommended using paclitaxel 175 mg/m2 administered on day 1 over approximately 3 hours as an intravenous infusion, followed by gemcitabine 1,250 mg/m2 as a 30-minute intravenous infusion on days 1 and 8 of each 21-day cycle. Dose reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient.
_**Monitoring for toxicity and dose modification due to toxicity**_
_Dose modification due to nonhematological toxicity_
Periodic physical examination and checks of renal and hepatic function should be made to detect nonhematological toxicity. Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient. In general, for severe (grade 3 or 4) nonhematological toxicity, except nausea/vomiting, therapy with gemcitabine should be withheld or decreased depending on the judgement of the treating physician. Doses should be withheld until toxicity has resolved in the opinion of the physician.
For cisplatin and paclitaxel dosage adjustment in combination therapy, please refer to the corresponding manufacturers’ prescribing information.
_Dose modification due to hematological toxicity_
Initiation of a cycle
For all indications, the patient must be monitored before each dose for platelet and granulocyte counts. Patients should have an absolute granulocyte count of at least 1,500 (x 106/l) and platelet count of 100,000 (x 106/l) prior to the initiation of a cycle.
Within a cycle
Dose modifications of gemcitabine within a cycle should be performed according to the following tables:
Dose modifications due to hematological toxicity in subsequent cycles, for all indications
The gemcitabine dose should be reduced to 75% of the original cycle initiation dose, in the case of the following hematological toxicities:
- Absolute granulocyte count <500 x 106/l for more than 5 days.
- Absolute granulocyte count <100 x 106/l for more than 3 days.
- Febrile neutropenia.
- Platelets <25,000 x 106/l.
- Cycle delay of more than 1 week due to toxicity.
_**Special populations**_
_Patients with renal or hepatic impairment_
Gemcitabine should be used with caution in patients with hepatic or renal impairment as there is insufficient information to allow for clear dose recommendations for this patient populations (see **Warnings and Precautions** and **Pharmacokinetics** – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). Dose reduction is recommended in patients with elevated serum bilirubin concentration because such patients are at increased risk of toxicity. The toxicity was mostly related to the liver. Patients with elevated serum creatinine concentration appeared to experience increased sensitivity to gemcitabine.
_Elderly population (>65 years)_
Gemcitabine has been well tolerated in patients over the age of 65. There is no evidence to suggest that dose adjustments, other than those already recommended for all patients, are necessary in elderly, although gemcitabine clearance and half-life are affected by age (see **Pharmacokinetics** – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_).
_Pediatric population (<18 years)_
Gemcitabine is not recommended for use in children under 18 years of age due to insufficient data on safety and efficacy.
_**Method of administration**_
Gemcitabine is tolerated well during infusion and may be administered ambulant. If extravasation occurs, generally the infusion must be stopped immediately and started again in another blood vessel. The patient should be monitored carefully after the administration.

- Indication Info
- **Indications:**
_**Non-small cell lung cancer (NSCLC)**_
