Amoxicillin is an antibiotic in a group of drugs called penicillins. Amoxicillin fights bacteria in the body. Clavulanate potassium is a form of clavulanic acid. It is used to overcome resistance in bacteria that secrete beta-lactamase, thereby counteracting possible bacterial resistance to the amoxicillin. The combination of amoxicillin and clavulanate potassium is used to treat many different infections caused by bacteria, such as sinusitis, pneumonia, ear infections, bronchitis, urinary tract infections, and infections of the skin. Amoxicillin and clavulanate potassium may also be used for purposes not listed in this medication guide.
Augmentin is an antibiotic used in the treatment of various bacterial infections. It works by fighting bacteria, including bacteria that penicillin can't fight.
