You may need to take a pregnancy test before using anastrozole, to make sure you are not pregnant.

You should not use this medication if you are allergic to anastrozole, if you are breast-feeding a baby, or if you have not yet completed menopause. Anastrozole is not for use in men or children.

Before using anastrozole, tell your doctor if you have heart disease, circulation problems, a history of stroke or blood clot, severe liver disease, high cholesterol, osteoporosis, or low bone mineral density.
