Amoxicillin (Amoxil®) is a prescription antibiotic approved to treat a variety of different infections. Although it is often used by itself, amoxicillin can also be combined with other antibiotics to treat certain infections.
Amoxicillin belongs to a group of medications known as aminopenicillins, which is part of a larger group of medications known as beta-lactam antibiotics (named after the ring-like "lactam" structure of these antibiotics). It works by stopping bacteria from making cell walls, which eventually causes the bacteria to die.
There are many different forms and strengths available for amoxicillin: tablets, chewable tablets, pediatric drops, oral suspension (liquid), and capsules. For most conditions, amoxicillin is usually taken by mouth two or three times a day (except for gonorrhea, which is treated with a single, one-time dose). It is important to finish your entire prescription, even if you start feeling better, to ensure that the infection is completely treated.
