If people are allergic to amoxicillin can they take cephalexin?
Amoxicillin belongs to a group of antibiotics called Penicillins. If you are allergic to Penicillins then you are more likely to be allergic to a group of antibiotics called Cephalosporins of which Cephalexin is a member. Cephalexin should be avoided in a penicillin allergic patient.
Antibiotics such as clarithromycin, doxycycline and erthyromycin may be safe alternatives for you.
