Amoxicillin

Trade Names: Amoxil, Polymox, Trimox, Wymox

Type of Drug: Amoxicillin is an antibiotic that belongs to the class of drugs called penicillins. Amoxicillin is used to treat gram-negative and some gram-positive bacteria. It is used to treat infections in the lungs, throat, sinuses, kidneys, bladder, and skin.

How Drug Works: Amoxicillin stops bacteria from making their protein cell wall, so the bacteria die. Penicillins can do this because they contain a special beta-lactam ring.

How Drug Is Given: Amoxicillin is a capsule taken by mouth 1 to 4 times a day. Take on an empty stomach, either 1 hour before or 2 hours after eating. The dose and frequency depend on the infection being treated. Keep the medicine in a tightly closed container and out of the reach of children and pets.
