Actually the PDR says Percocet is "probably safe" to use during breastfeeding. If you still have concerns, talk to your pharmacist about it. Most pharmacists are quite happy to discuss your medications with you.
We have a great thread on Pregnancy, Motherhood and Chronic Pain in our forum. Several other mothers have shared what medications they took during pregnancy and breastfeeding. Feel free to join the discussion, share your concerns and ask questions. (Note: If you've never been to the forum before, you'll have to register separately from your registration here on ChronicPainConnection. You can, however, use the same e-mail address and password if you like to make it easier to remember.)
