Amoxicillin is used to treat a wide variety of bacterial
infections. This medication is a penicillin-type antibiotic. It works by

This antibiotic treats only bacterial infections. It
will not work for viral infections (such as common cold, flu). Using any
antibiotic when it is not needed can cause it to not work for future
infections.
Amoxicillin is also used with other medications to treat
stomach/intestinal ulcers caused by the bacteria H. pylori and to prevent
the ulcers from returning.
