Fluoxymesterone

Why this is used

Fluoxymesterone, an androgenic hormone, is similar to the male hormone testosterone. It is prescribed for males when this hormone is absent or low or to treat delayed onset of puberty in males. It is also used in females with certain kinds of breast cancer. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How to take it

Fluoxymesterone comes as a tablet to take by mouth. It usually is taken once a day or three or four times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take fluoxymesterone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Continue to take fluoxymesterone even if you feel well. Do not stop taking fluoxymesterone without talking to your doctor.
