Macrolides.
Zithromax and Biaxin are both macrolide antibiotics. They belong to the same family (Macrolide antibiotics) Often if a patient experiences an allergic reaction to one member of an antibiotic family it is likely they could be allergic to an other member.

Every time I get sinus infection...doc prescribes Z-PAK...even tho it is clearly marked on my chart of my allergy.
