Hi, I just applied topicort (0.05%) to a poison oak rash on my arms. How long until I can safely breastfeed my baby?

Stays on skin: You can breastfeed your baby right away as long as your rash does not come in contact with the baby. The poison oak toxin sticks tenaciously to your skin, and the most important thing is to remove it so you don't spread the rash by direct contact with your baby. Scrub your affected skin with "Tecnu" or other soap designed to remove poison oak from your skin. Don't let the rash touch the baby. ...Read more
