DOSAGE AND ADMINISTRATION
The recommended dose of AROMASIN in early and advanced breast cancer is one 25 mg tablet once daily after a meal.
In postmenopausal women with early breast cancer who have been treated with 2–3 years of tamoxifen, treatment with AROMASIN should continue in the absence of recurrence or contralateral breast cancer until completion of five years of adjuvant endocrine therapy.
For patients with advanced breast cancer, treatment with AROMASIN should continue until tumor progression is evident.
For patients receiving AROMASIN with a potent CYP 3A4 inducer such as rifampicin or phenytoin, the recommended dose of AROMASIN is 50 mg once daily after a meal.
The safety of chronic dosing in patients with moderate or severe hepatic or renal impairment has not been studied. Based on experience with exemestane at repeated doses up to 200 mg daily that demonstrated a moderate increase in non-life threatening adverse events, dosage adjustment does not appear to be necessary (see CLINICAL PHARMACOLOGY, Special Populations and PRECAUTIONS).
