Provera and Breastfeeding

Studies on Provera (medroxyprogesterone) and breastfeeding have shown that the hormone in this medication does pass through breast milk in low amounts. These small amounts are not thought to harm the nursing infant and will not affect the production or quality of breast milk. However, you should not breastfeed while using Provera in combination with an estrogen.

Can Breastfeeding Women Take Provera?

Provera® (medroxyprogesterone acetate) is a prescription medicine that contains medroxyprogesterone, a synthetic (manufactured) form of the female hormone progesterone. Provera passes through breast milk. Thus, the manufacturer recommends that women not use this drug while breastfeeding. However, many experts consider it safe for use in women who are nursing.

More Information on Provera and Breastfeeding

As mentioned, the hormone in Provera is known to pass through breast milk in small amounts. However, studies indicate that using the medicine while breastfeeding will not harm the nursing infant. In addition, unlike estrogen hormones, Provera will not affect the production or quality of breast milk. This is one of the reasons why progestin-only birth control is the preferred hormonal birth control option for women who are nursing.
Because estrogen affects breast milk supply, estrogen-containing medicines are not recommended for women who are breastfeeding. Therefore, you should not use Provera in combination with an estrogen if you are nursing.

Talking With Your Healthcare Provider

You should discuss breastfeeding and Provera use with your healthcare provider. Each woman's situation is different, and you and your healthcare provider understand your situation best. After considering what you want and expect, as well as your current health situation, the two of you can make a shared decision that is right for you.
