Makena and Breastfeeding
Although Makena (hydroxyprogesterone caproate) probably passes through breast milk, it is unlikely that it would be recommended for a breastfeeding woman. In most cases, the drug is stopped by week 37 of pregnancy. If you are breastfeeding and considering Makena, consult your healthcare provider about the potential benefits and risks.
Makena™ (hydroxyprogesterone caproate) is an injectable medication used during pregnancy to help prevent repeat preterm births (early deliveries). This medication probably passes through breast milk. It would be unusual for a woman to take Makena while breastfeeding.
Makena is a progestin hormone, and progestins are known to pass through breast milk in small amounts. However, this is not usually considered a problem; in fact, the type of birth control pills usually recommended for breastfeeding women (progestin-only pills or "mini-pills") contain progestins.
Typically, a breastfeeding woman wouldn't be using Makena in the first place. The drug should be stopped either by 37 weeks of pregnancy or by delivery, whichever comes first. However, it is conceivable that a woman who is still breastfeeding an older child might need to use Makena while both pregnant and breastfeeding. Since many healthcare providers recommend that women with a history of preterm labor avoid breastfeeding while pregnant, breastfeeding while taking Makena is expected to be rare.
You should discuss breastfeeding and Makena 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.
