Amoxicillin

Table of Contents

Amoxicillin is a type of penicillin drug that fights off bacteria. Amoxicillin can be used to treat numerous types of infections that cause bacteria, such as tonsillitis, bronchitis, pneumonia, and infections in your ears, nose, throat, skin, or urinary tract.

There are many brands and forms of amoxicillin available. Sometimes amoxicillin can be used in conjunction with other antibiotics such as clarithromycin (Biaxin) to treat stomach ulcers that cause helicobacter pylori infection. This combination sometimes also works with a gastric acid reducer known as lansoprazole (Prevacid).

Consult a general practitioner or specialist doctor through Smarter Health if you have further questions.
