What is Augmentin?
Clavulanate potassium is a beta-lactamase inhibitor that helps prevent certain bacteria from becoming resistant to amoxicillin.
You should not use Augmentin if you have severe kidney disease, if you have had liver problems or jaundice while taking amoxicillin and clavulanate potassium, or if you are allergic to any penicillin or cephalosporin antibiotic, such as Amoxil, Ceftin, Cefzil, Moxatag, Omnicef, and others.
If you switch from one tablet form to another (regular, chewable, or extended-release tablet), take only the new tablet form and strength prescribed for you. Amoxicillin and clavulanate may not be as effective or could be harmful if you do not use the exact tablet form your doctor has prescribed.
Augmentin can make birth control pills less effective. Ask your doctor about using a non-hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while taking Augmentin.
Before taking this medicine

Do not crush or chew the extended-release tablet. Swallow the pill whole, or break the pill in half and take both halves one at a time. If you have trouble swallowing a whole or half pill, talk with your doctor about using another form of amoxicillin and clavulanate potassium.
The chewable tablet must be chewed before you swallow it.
Shake the liquid medicine well just before you measure a dose. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Augmentin will not treat a viral infection such as the flu or a common cold.
