Augmentin XR : Uses, Side Effects, Interactions & More
Why is this medication prescribed?
Augmentin XR (Amoxicillin and Clavulanic Acid) is used to treat certain infections caused by bacteria, including infections of the ears, lungs, sinuses, skin, and urinary tract. Amoxicillin is in a class of drugs called penicillin-like antibiotics. It works by stopping the growth of bacteria. Clavulanic acid belongs to a class of medications called beta-lactamase inhibitors. It works by preventing bacteria from destroying amoxicillin.
Antibiotics do not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases the risk of getting an infection later that resists antibiotic treatment.
How should this medicine be used?
Augmentin XR (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 beginning 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 remind you to take Augmentin XR, take them around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any parts you don’t understand. Take Augmentin XR exactly as directed. Do not take more or less, 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 medicine evenly.
The chewable tablets should be chewed completely before swallowing. The other tablets should be taken with a full glass of water.
Augmentin XR 250 mg and 500 mg tablets contain the same amount of clavulanic acid. Do not substitute two 250 mg tablets for one 500 mg. The 250 mg regular tablet and the 250 mg chewable tablet contain different amounts of clavulanic acid. Nor should they be replaced.
Take Augmentin XR until the prescription is finished, even if you feel better. If you stop taking Augmentin XR too soon, or miss doses, your infection may not be fully treated and the bacteria may become resistant to the antibiotics.

Augmentin XR are also sometimes used to treat certain sexually transmitted diseases (STDs). Talk to your doctor about the possible risks of using this drug for your condition.
