I have been prescribed erythromycin for a dodgy tooth, forgot to mention to the dentist that I'm BF although I'm not sure he'd have been an expert on it anyway. I have googled and checked Kellymom and the consensus seems to be that it's fine to take while BF. But when I went to Boots to get it, the leaflet in the box said it wasn't suitable to take while BF. Can anyone advise who's right?
