If you are taking Evamist and breastfeeding or plan to start breastfeeding, it is important to know that the estrogen in this medication does pass through breast milk in low amounts. These amounts are probably too low to cause significant problems in breastfed infants, but they may decrease the production and quality of breast milk. Before taking Evamist, breastfeeding women should ask their healthcare providers about the potential risks.
Can I Use Evamist While Breastfeeding?
Evamist® (estradiol transdermal spray) is a prescription hormone replacement medication used to treat menopause symptoms. It contains estradiol, which is an estrogen. As with all estrogen medications, Evamist is not recommended for women who are breastfeeding. Therefore, make sure to check with your healthcare provider before taking Evamist if you are breastfeeding (or planning to start).
Problems With Evamist and Breastfeeding
The estrogen hormone in Evamist is absorbed through the skin, enters the bloodstream, and passes through breast milk. However, it passes through breast milk in amounts that are probably too low to cause significant or long-lasting problems in nursing infants.
The real problem with Evamist and breastfeeding is that the estrogen hormones in Evamist may decrease the production and quality of breast milk. It is for this reason that estrogen-containing medications (including Evamist and many birth control pills) are not usually recommended for women who are breastfeeding.
Talking With Your Healthcare Provider About Evamist and Breastfeeding
You should talk with your healthcare provider about Evamist 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 Evamist and breastfeeding that is right for you.
