(sef' a klor)

WHY is this medicine prescribed?

Cefaclor is used to treat certain infections caused by bacteria, such as pneumonia and other lower respiratory tract (lung) infections; and infections of the skin, ears, throat, tonsils, and urinary tract. Cefaclor is in a class of medications called cephalosporin antibiotics. It works by stopping the growth of bacteria.

Antibiotics such as cefaclor 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?

Cefaclor comes as a capsule, an extended-release (long-acting) tablet, and a suspension (liquid) to take by mouth. The capsule and liquid are usually taken with or without food every 8 or 12 hours . The long-acting tablet is usually taken within 1 hour of eating a meal every 12 hours (twice a day) for 7 to 10 days . Take cefaclor at 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 cefaclor exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Shake the suspension well before each use to mix the medication evenly.

Swallow the long-acting tablets whole; do not split, chew, or crush them.

You should begin to feel better during the first few days of treatment with cefaclor. If your symptoms do not improve or get worse, call your doctor.

Take cefaclor until you finish the prescription, even if you feel better. If you stop taking cefaclor 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?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
