Lawrence's book indicates that can nurse with syphillis once mom is aeuqately treated. She is a little uncler as to what adequately is. I once saw another reference that said after 24 hours of PCN. So, if mom want to be ery caustious she could wait till 10 day course of PCN but I would probably nurse after 24 hours esp if baby is also being treated. -- **************************************************** * Deena Zimmerman MD MPH * * Department of Pediatrics * * UMDNJ-Robert Wood Johnson Medical School * * 1 RWJ Place * * New Brunswick, NJ 08903 * * * * phone (908) 235-7248 * * fax (908) 235-7345 * * email [log in to unmask] (internet) * ****************************************************
