Medroxyprogesterone acetate (MPA), also known as depot medroxyprogesterone acetate (DMPA) in injectable form and sold under the brand name Depo-Provera among others, is a hormonal medication of the progestin type.[10][3] It is used as a method of birth control and as a part of menopausal hormone therapy.[10][3] It is also used to treat endometriosis, abnormal uterine bleeding, abnormal sexuality in males, and certain types of cancer.[10] The medication is available both alone and in combination with an estrogen.[12][13] It is taken by mouth, used under the tongue, or by injection into a muscle or fat.[10]

Common side effects include menstrual disturbances such as absence of periods, abdominal pain, and headaches.[10] More serious side effects include bone loss, blood clots, allergic reactions, and liver problems.[10] Use is not recommended during pregnancy as it may harm the baby.[10] MPA is an artificial progestogen, and as such activates the progesterone receptor, the biological target of progesterone.[3] It also has weak glucocorticoid activity and very weak androgenic activity but no other important hormonal activity.[3][14] Due to its progestogenic activity, MPA decreases the body's release of gonadotropins and can suppress sex hormone levels.[15] It works as a form of birth control by preventing ovulation.[10]

MPA was discovered in 1956 and was introduced for medical use in the United States in 1959.[16][17][10] It is on the World Health Organization's List of Essential Medicines.[18] The wholesale cost in the developing world is about US$0.60–1.60 per vial.[19] In the United Kingdom this dose costs the NHS about £6.[20] In the United States it costs less than $25 a dose as of 2015.[21] MPA is the most widely used progestin in menopausal hormone therapy and in progestogen-only birth control.[22][23] DMPA is approved for use as a form of long-acting birth control in more than 100 countries.[24][25] In 2017, it was the 222nd most commonly prescribed medication in the United States, with more than two million prescriptions.[26][27]
