Hi all, I've been lurking for a while and will do a more formal intro of myself in my next post but at the moment I need help: Mother bf 10 mo. old, has acute bronchitis/poss. pneumonia, allergic to penicillin MD has prescribed Biaxin and instructed mother to wean. Pharmacist told me this is also known as Clarithromicin and that it is not known whether there are any contraindications at this time. Does anyone have more info?
