CombiPatch and Breastfeeding
It is generally recommended that breastfeeding women avoid using estrogen-containing medications (such as CombiPatch). The main concern with CombiPatch and breastfeeding is that the hormones in the medication can reduce the quality and production of breast milk. Therefore, before starting CombiPatch, breastfeeding women should talk to their healthcare providers about the potential risks.
CombiPatch® (estradiol/norethindrone patch) is a prescription medication typically used to treat menopause symptoms (although it is approved for various other uses as well). It contains both an estrogen (estradiol) and a progestin (norethindrone). Because it contains estrogen, CombiPatch is not recommended for breastfeeding women. Therefore, make sure to check with your healthcare provider before taking CombiPatch if you are breastfeeding (or planning to start).
Estradiol and norethindrone (the active ingredients of CombiPatch) pass through breast milk in humans. However, the hormones pass through breast milk in amounts that are probably too low to cause significant or long-lasting problems in breastfeeding infants.
Of greater concern, estrogen medications often decrease the production and quality of breast milk. It is for this reason that estrogen-containing medications (including CombiPatch) are usually not recommended for women who are breastfeeding.
You should talk with your healthcare provider about CombiPatch and breastfeeding. 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, you and your healthcare provider can make a shared decision about CombiPatch and breastfeeding that is right for you.
