Yes, it is generally safe to breastfeed while on Humira. However, as with any medication, there are potential risks associated with taking it while breastfeeding. Specifically for Humira (adalimumab), the American College of Obstetricians and Gynecologists (ACOG) states that “the minimal systemic absorption of adalimumab is unlikely to pose a risk” when used during breastfeeding. Therefore, they recommend discussing the benefits and risks with your doctor before deciding whether or not to take this medication while nursing.
