Amoxicillin is a penicillin antibiotic that fights bacteria in the body. Clavulanate potassium is a beta-lactamase inhibitor that helps prevent certain bacteria from becoming resistant to amoxicillin. Amoxicillin and clavulanate potassium is a combination medicine used to treat many different infections caused by bacteria, such as sinusitis, pneumonia, ear infections, bronchitis, urinary tract infections, and infections of the skin. You should not use this medicine if you have severe kidney disease, if you have had liver problems or jaundice while taking amoxicillin and clavulanate potassium, or if you are allergic to any penicillin or cephalosporin antibiotic, such as Amoxil, Ceftin, Cefzil, Levaquin, Moxatag, Omnicef, and others. If you switch from one tablet form to another (regular, chewable, or extended-release tablet), take only the new tablet form and strength prescribed for you. Amoxicillin and clavulanate may not be as effective or could be harmful if you do not use the exact tablet form your doctor has prescribed. Amoxicillin and clavulanate potassium can pass into breast milk and may harm a nursing baby. This combination results in an antibiotic with an increased spectrum of action and restored efficacy against amoxicillin-resistant bacteria that produce β-lactamase. Possible side effects include diarrhea, vomiting, nausea, thrush, and skin rash. As with all antimicrobial agents, antibiotic-associated diarrhea due to Clostridium difficile infection—sometimes leading to pseudomembranous colitis—may occur during or after treatment with amoxicillin/clavulanic acid. Rarely, cholestatic jaundice (also referred to as cholestatic hepatitis, a form of liver toxicity) has been associated with amoxicillin/clavulanic acid. The reaction may occur up to several weeks after treatment has stopped, and usually takes weeks to resolve. It is more frequent in men, older people, and those who have taken long courses of treatment; the estimated overall incidence is one in 100,000 exposures. Amoxicillin/clavulanic acid is the International Nonproprietary Name (INN) and co-amoxiclav is the British Approved Name (BAN). Many branded products indicate their strengths as the quantity of amoxicillin.
