How Does It Work?
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.
