what family does doxycycline belong to
Penicillin allergy is an overreaction by your immune system to penicillin and other antibiotics in the beta-lactam family and closely related antibiotics. Doxycycline belongs to a class of drugs called Tetracyclines. Tetracyclines are unrelated to penicillins and therefore safe to take in hypersensitive patients. Other unrelated antibiotics include quinolones (e.g. ciprofloxacin), macrolides (e.g. clarithromycin), aminoglycosides (e.g. gentamicin) and glycopeptides (e.g. vancomycin).
