Amoxicillin is a type of antibiotic that belongs to the penicillin family. It is commonly used to treat various bacterial infections, including those affecting the ears, throat, and urinary tract. Amoxicillin works by stopping the growth of bacteria, helping the body to fight off infections more effectively. This medication is usually taken by mouth in the form of capsules, tablets, or liquid. It is important to complete the full course of amoxicillin as prescribed by a healthcare provider, even if symptoms improve, to ensure that the infection is fully cleared and to prevent antibiotic resistance.
