Medroxyprogesterone acetate works similar to the progesterone hormone naturally produced by the body. It helps in regulating the periods, stopping irregular bleeding and for controlling the withdrawal bleeding in case of amenorrhea (unusual stopping of menstrual periods). It is also used to prevent endometrial hyperplasia (thickening of the lining of the uterus) in women who are taking conjugated estrogens.

Take it strictly as advised by your doctor. The number of doses and the duration will depend on the medical problem you are being treated for. You can take it with or without food, preferably at the same time of each day to ensure consistent levels of medicine in your body.

Ideally, you should not miss any dose during any treatment. Missing a dose may increase the likelihood of breakthrough vaginal bleeding or spotting (blood stain). However, if you miss a dose, take it as soon as you remember. However, if it is almost time for the next dose, skip the missed dose and continue with the usual dosing schedule.

The common side effects of Medroxyprogesterone acetate include headache, nausea (feeling sick), weight gain, breast pain, and unusual vaginal bleeding or spotting. Do not worry, most of these symptoms are temporary. However, if they persist, check with your doctor as soon as possible.

No, Medroxyprogesterone acetate is not a contraceptive. You should use an effective form of birth control to prevent pregnancy. If you think you have become pregnant while using the medicine, tell your doctor right away to avoid any harm to the baby.
