Amoxicillin is a penicillin-type antibiotic. Doctors prescribe it for many common bacterial infections. It does not work against viruses, so it will not help colds or flu.
What Is Amoxicillin Used For?
- Ear, nose, and throat infections
- Chest infections such as pneumonia and bronchitis
- Urinary tract infections
- Skin infections
- Dental infections
- Helicobacter pylori infection, together with other medicines
How Does Amoxicillin Work?
Amoxicillin stops bacteria from building their cell walls. The bacteria weaken and die, and your immune system clears the infection.
