Amoxicillin is a penicillin antibiotic that fights bacteria.

Amoxicillin is used to treat many different types of infectioncaused by bacteria, such as tonsillitis, bronchitis, pneumonia, gonorrhea, and infections of the ear, nose, throat, skin, or urinary tract.

Amoxicillin is also sometimes used together with another antibiotic called clarithromycin  to treat stomach ulcers caused by Helicobacter pylori infection. This combination is sometimes used with a stomach acid reducer called lansoprazole
