Amoxicillin and clavulanate potassium can pass into breast milk and may affect the nursing baby. Tell your doctor if you are breast-feeding.

Do not give this medicine to a child without medical advice.

The liquid or chewable tablet may contain phenylalanine. Talk to your doctor before using these forms of this medicine if you have phenylketonuria (PKU).

How should I take amoxicillin and clavulanate potassium?

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Take the medicine every 12 hours, at the start of a meal to reduce stomach upset.

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.

Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Amoxicillin and clavulanate potassium will not treat a viral infection such as the flu or a common cold.

This medicine can cause unusual results with certain lab tests for glucose (sugar) in the urine. Tell any doctor who treats you that you are using amoxicillin and clavulanate potassium.

Overdose can cause nausea, vomiting, stomach pain, diarrhea, skin rash, drowsiness, hyperactivity, and decreased urination.

What should I avoid while taking amoxicillin and clavulanate potassium?

Avoid taking this medicine together with or just after eating a high-fat meal. This will make it harder for your body to absorb the medication.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.
