Amoxicillin + Clavulanate is a combination antibiotic used to treat a wide range of bacterial infections. It contains:Amoxicillin, a penicillin-type antibiotic that kills bacteria, andClavulanate potassium (clavulanic acid), a beta-lactamase inhibitor that helps prevent certain bacteria from becoming resistant to amoxicillin.This combination enhances the effectiveness of amoxicillin against bacteria that produce beta-lactamase enzymes. It's commonly used for infections such as sinusitis, pneumonia, urinary tract infections, and skin infections.
