How it works
Medroxyprogesterone belongs to a class of drugs called progestins. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.
Medroxyprogesterone is a form of progesterone, a hormone your body makes. Medroxyprogesterone can help regulate other hormones in your body. This drug works in different ways, depending on why your doctor is giving it to you.
