I have a client diagnosed w/ giardia; baby is 4 wk. old. Her physician prescribed a 5 day course of Flagyl w/ bf hold for 1 wk. I told her of alternative single 2 gm dose & also furazolidone, mentioned in BF Ans. Book. Can't find the latter med. in 1995 ed. Meds. & Mothers' Milk. Any insight would be helpful. Thanks. Sara C.
