Faslodex Dosage/Direction for Use

Adult females (including Elderly): The recommended dose is 500 mg at intervals of one month, with an additional 500 mg dose given two weeks after the initial dose.
Special populations: Renal impairment: No dose adjustments are recommended for patients with mild to moderate renal impairment (creatinine clearance ≥30 ml/min). Safety and efficacy have not been evaluated in patients with severe renal impairment (creatinine clearance <30 ml/min), and, therefore, caution is recommended in these patients (see Precautions).
Hepatic impairment: No dose adjustments are recommended for patients with mild to moderate hepatic impairment. However, as fulvestrant exposure may be increased, Faslodex should be used with caution in these patients. There are no data in patients with severe hepatic impairment (see Pharmacology: Pharmacokinetics under Actions, Contraindications and Precautions).
Paediatric population: The safety and efficacy of Faslodex in children from birth to 18 years of age have not been established. Currently available data are described in Pharmacology: Pharmacodynamics and Pharmacokinetics under Actions, but no recommendation on a posology can be made.
Method of administration: Faslodex should be administered as two consecutive 5 ml injections by slow intramuscular injection (1-2 minutes/injection), one in each buttock (gluteal area).
Caution should be taken if injecting Faslodex at the dorsogluteal site due to the proximity of the underlying sciatic nerve.
