Amoxicillin is a penicillin-type antibiotic used to treat a wide range of bacterial infections, including respiratory tract infections, ear infections, urinary tract infections, and skin infections. It works by inhibiting bacterial cell wall formation, leading to the destruction of the bacteria. Amoxicillin is commonly prescribed in capsule form for its effectiveness and ease of use. To ensure the best results, it should be taken exactly as prescribed, and the full course should be completed even if symptoms improve early, to prevent antibiotic resistance.
