A member asked:
Is it safe to take zithromax if you are allergic to penicillin?
A doctor has provided 1 answer
Yes: Zithromax (azithromycin) is an antibiotic in the class called macrolides---similar to Erythromycin and Clarithromycin (biaxin). Penicillin is in a completely different class so there is no cross reactivity.
