    HOW should this medicine be used?

    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.

    Fluoxymesterone may cause an upset stomach. Take fluoxymesterone with food or milk.

    What should I do IF I FORGET to take a dose?

    Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
    Call your doctor for directions if you miss more than one dose.
