WHY is this medicine prescribed?
The combination of amoxicillin and clavulanic acid is used to treat certain infections caused by bacteria, including infections of the ears, lungs, sinus, skin, and urinary tract. Amoxicillin is in a class of medications called penicillin-like antibiotics. It works by stopping the growth of bacteria. Clavulanic acid is in a class of medications called beta-lactamase inhibitors. It works by preventing bacteria from destroying amoxicillin.
Antibiotics will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
HOW should this medicine be used?
The combination of amoxicillin and clavulanic acid comes as a tablet, a chewable tablet, an extended-release (long-acting) tablet, and a suspension (liquid) to take by mouth. The tablets, chewable tablets, and suspension are usually taken at the start of a meal every 8 hours (three times a day) or every 12 hours (twice a day). The extended-release tablets are usually taken with a meal or snack every 12 hours (twice a day). To help you remember to take amoxicillin and clavulanate, take it around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take amoxicillin and clavulanic acid exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release tablets whole; do not chew or crush them.
Shake the liquid well before each use to mix the medication evenly.
The chewable tablets should be chewed thoroughly before they are swallowed. The other tablets should be taken with a full glass of water.
The 250 mg and 500 mg tablets of amoxicillin and clavulanic acid contain the same amount of clavulanic acid. Do not substitute two 250 mg tablets for one 500 mg tablet. The 250 mg regular tablet and the 250 mg chewable tablet contain different amounts of clavulanic acid. They also should not be substituted.
Take amoxicillin and clavulanic acid until you finish the prescription, even if you feel better. If you stop taking amoxicillin and clavulanic too soon, or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Are there OTHER USES for this medicine?
Amoxicillin and clavulanic acid also is used sometimes to treat certain sexually transmitted diseases (STD). Talk to your doctor about the possible risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

What should I know about STORAGE and DISPOSAL of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store the tablets at room temperature and away from excess heat and moisture (not in the bathroom). Keep liquid medication in the refrigerator, tightly closed, and dispose of any unused medication after 10 days. Do not freeze.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet.

See the FDA's Safe Disposal of Medicines website ( Web Site) for more information if you do not have access to a take-back program.
