Question: are erythromycin and amoxicillin the same?
Answer: Erythromycin is a macrolide antibacterial with a spectrum similar, however not identical to penicillin. Erythromycin is therefore commonly used in penicillin-allergic patients. Co-amoxiclav (brand name Augmentin) is a combination of amoxicillin, broad-spectrum penicillin and clavulanic acid, a beta lactamase inhibitor.
