Key takeaways
Augmentin (amoxicillin/clavulanate) and cephalexin are both antibiotics used to treat bacterial infections, but they belong to different classes. Augmentin is a combination of a penicillin antibiotic and a beta-lactamase inhibitor, which helps it fight bacteria that might be resistant to amoxicillin alone. Cephalexin, on the other hand, is a cephalosporin antibiotic that works by preventing bacteria from forming a protective covering. Augmentin is typically taken two to three times a day, while cephalexin is taken two to four times a day. Both medications are available in generic forms and can be used in adults and children. Common side effects for both include diarrhea, nausea, and rash, but Augmentin can also cause liver problems and is not recommended for those with a severe penicillin allergy. Cephalexin might be a better option if you have a mild penicillin allergy, but it can increase the risk of seizures and bleeding, especially in people with kidney problems.
