What is depot medroxyprogesterone acetate?
Depot medroxyprogesterone acetate is the injectable (given by shot) form of a lab-made hormone called medroxyprogesterone acetate. It has been used to prevent pregnancy (as birth control). Depot medroxyprogesterone acetate can also be used to treat some problems linked to a person’s period (menstrual disorders) and, at high doses, can be used to treat certain types of cancer. This fact sheet will cover the use of the depot medroxyprogesterone acetate shot for birth control. Depot medroxyprogesterone acetate is not the same as oral birth control pills (pills taken by mouth), which contain other hormones. Depot medroxyprogesterone acetate is sold under the brand name Depo Provera®.

Breastfeeding while taking depot medroxyprogesterone acetate:
Depot medroxyprogesterone acetate gets into breast milk in small amounts and is not expected to negatively affect a child’s long-term growth and development. According to the World Health Organization (WHO), use of depot medroxyprogesterone while breastfeeding is usually not recommended less than 6 weeks after the baby’s birth. But the benefit of using the medication and breastfeeding your baby may outweigh possible risks. Your healthcare providers can talk with you about using depot medroxyprogesterone acetate and what medication is best for you. Be sure to talk to your healthcare provider about all your breastfeeding questions.
If a male takes depot medroxyprogesterone acetate, could it affect fertility or increase the chance of birth defects?
Studies have not been done to see if depot medroxyprogesterone acetate could affect male fertility (ability to get partner pregnant) or increase the chance of birth defects above the background risk. In general, exposures that fathers or sperm donors have are unlikely to increase risks to a pregnancy.
