Amoxicillin-clavulanate is a combination antibiotic used to treat various bacterial infections. It contains amoxicillin, which is a penicillin-type antibiotic that fights bacteria, and clavulanate, which helps prevent bacteria from becoming resistant to amoxicillin. This combination makes it effective against a wider range of bacteria. Commonly prescribed for conditions like sinus infections, pneumonia, and urinary tract infections, amoxicillin-clavulanate is available in various forms, including tablets and liquid. It is important to take the medication as directed by a healthcare provider to ensure its effectiveness and reduce the risk of antibiotic resistance.
