Cephalexin is an antibiotic in a class of drugs called cephalosporins. Cephalosporins (sef-a-loe-SPOR-ins) are used in the treatment of infections caused by bacteria. They work by killing bacteria or preventing their growth. It works by interfering with the bacteria's cell wall formation. This weakens the cell wall, causing it to rupture, and kills the bacteria. Take all of the cephalexin that has been prescribed for you even if you begin to feel better. Your symptoms may start to improve before the infection is completely treated. Tell your doctor if you have ever had any unusual or allergic reaction to any of the cephalosporins, penicillins, penicillin-like medicines, or penicillamine. Tell your doctor or pharmacist if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement.
