Uses of Medroxyprogesterone
Medroxyprogesterone is used to treat abnormal menstruation (periods) or irregular vaginal bleeding. Medroxyprogesterone is also used to bring on a normal menstrual cycle in women who menstruate normally in the past but have not menstruated for at least 6 months and who are not pregnant or undergoing menopause (change of life). Medroxyprogesterone is also used to prevent overgrowth of the lining of the uterus (womb) and may decrease the risk of cancer of the uterus in patients who are taking estrogen. Medroxyprogesterone is in a class of medications called progestins. It works by stopping the growth of the lining of the uterus and by causing the uterus to produce certain hormones.

Dosage
Medroxyprogesterone comes as a tablet to take by mouth. It is usually taken once a day on certain days of a regular monthly cycle. To help you remember to take medroxyprogesterone, take it at around the same time every day on the days you are scheduled to take it. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take medroxyprogesterone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Medroxyprogesterone may control your condition but will not cure it. Continue to take medroxyprogesterone according to your monthly schedule even if you feel well. Do not stop taking medroxyprogesterone without talking to your doctor.
