DOSING: The recommended dose of anastrozole is one tablet (1 mg) by mouth once daily.

DRUG INTERACTIONS: Anastrozole should not be used with tamoxifen because tamoxifen can reduce anastrozole levels in the body and decrease its therapeutic effects.

Estrogens decrease the effect of anastrozole by increasing estrogen levels in the body.

PREGNANCY: Anastrozole is not recommended for pregnant mothers under any circumstances. Anastrozole may cause fetal harm and terminate pregnancy.

NURSING MOTHERS: It is not known whether anastrozole enters breast milk. It should not be administered to nursing mothers to avoid any harm to the newborn.
