I have to say I am a bit worried about this discussion - and hold myself partly responsible. What I should have suggested in the first place is that if you (anyone!) has an enquiry they should ring Rodney Whyte at the Monash medical centre Ph 9594 2361. However I thought enough information had been presented to demonstrate that it was safe in breastfeeding. Actually almost all medications are. I am just concerned that some would be so worried they might believe that formula was preferable to her own milk. The lactmed info is also very good and from a reputable source. Hope that tooth is better
