Amoxicillin/clavulanic acid, also known as co-amoxiclav or amox-clav, sold under the brand name Augmentin, among others, is an antibiotic medication used for the treatment of a number of bacterial infections.[5] It is a combination consisting of amoxicillin, a β-lactam antibiotic, and potassium clavulanate, a β-lactamase inhibitor.[5] It is specifically used for otitis media, streptococcal pharyngitis, pneumonia, cellulitis, urinary tract infections, and animal bites.[5] It can be administered orally or intravenously.[2]

Common side effects include diarrhea, vomiting, and allergic reactions.[5] It also increases the risk of yeast infections, headaches, and blood clotting problems.[2][6] It is not recommended in people with a history of a penicillin allergy.[2] It is relatively safe for use during pregnancy.[5]

Amoxicillin/clavulanic acid was approved for medical use in the United States in 1984.[5] It is on the World Health Organization's List of Essential Medicines.[7][8] The World Health Organization classifies amoxicillin/clavulanic-acid as critically important for human medicine.[9] It is available as a generic medication.[5] In 2022, it was the 96th most commonly prescribed medication in the United States, with more than 6 million prescriptions.[10][11]
