My drugs that I worry may interact with azithromycin are: Metoprolol, Isosorbide, and Hz Tc. My former PA would never prescribe the z-pack, but a new doctor says it shouldn't bother me. I have a dental infection and this doctor wants me to stay on antibiotics until my dental surgery in a couple weeks. Please if you know please tell me asap. I have already put off taking this prescription for a week now. Thanks...
