Important information

You should not use this medicine 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, Levaquin, 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.

Amoxicillin and clavulanate potassium can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

Amoxicillin and clavulanate potassium 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 amoxicillin and clavulanate potassium.
