Regulatory Context

The U.S. Food and Drug Administration (FDA) initially approved Depo-Provera in 1992 for use as a contraceptive injection. In 2017, the FDA updated the label to reflect new safety data and potential risks. Health care providers should carefully consider the benefits and risks of Depo-Provera for each individual patient before prescribing.
