Is progesterone safe to use while I am nursing my baby?

Dr. Michael Roizen, MD
Internal Medicine
Progesterone can enter the breast milk while you are nursing your baby. However, the actual amount that enters the breast milk is very small, and would be unlikely to harm your nursing baby. The American Academy of Pediatrics rates progesterone as “compatible” with breastfeeding, suggesting that it should be safe to nurse while on progesterone. However, it’s best to talk to your doctor if you are nursing your baby and planning on taking progesterone. Together you will weigh the risks and the benefits and figure out the best plan of action for you and your baby.
Progesterone is excreted in the breast milk that you give your baby. However, after having a baby, the most common situation in which you would be on progesterone is if you have had a progesterone-containing intrauterine device (IUD) implanted for birth control. In this case, the amount of progesterone that your baby would be exposed to is so small that it would probably not cause any harm. The American Academy of Pediatrics considers progesterone “compatible” with breastfeeding, though you should still be careful while nursing. If you notice anything unusual about your baby and are wondering if it relates to the progesterone you are taking, talk with your baby's pediatrician.
