Any clue as to why would you put nitro over a plugged milk duct? The only indications I know of for nitro is as a potent coronary vasodilator and antianginal. This isn't a benign drug. A topical application could cause serious side effects in the mother, such as tachycardia, syncope, collapse or postural hypotension, not to mention a pounding headache. Please enlighten and any other pharmacophobes on the list! Maurenne Griese, RNC, BSN, CCE, CBE Birth and Breastfeeding Resources http://www.childbirth.org/bbfr Manhattan, KS USA [log in to unmask]
