The following drugs can potentially interact with amoxicillin: chloramphenicol, erythromycin, tetracycline, aminoglycosides, cephalosporins and probenecid. Contact your veterinarian if your pet experiences any unusual reactions when different medications are given together. Allergic reactions to medications may occur.
