Cefaclor is good at treating many types of bacterial infections with fewer side effects. It’s a commonly used antibiotic in a surgical procedure as a preventive measure to avoid infection. It is suitable for adults, children, and even pregnant women. Cefaclor comes in a capsule form, extended-release tablet, and suspension to take orally. It belongs to the group of drugs known as cephalosporin, a second-generation antibiotic. Cefaclor is a broad-spectrum antibiotic that means it active against many types of bacteria. It has the same action as the penicillin antibiotic.

It prevents bacteria from replicating and spreading by disrupting the synthesis of the peptidoglycan layer of the bacterial cell wall. This impairs the bond that holds the wall together causing holes to appear.

Getting the Best Result from Cefaclor

  • Cefaclor is effective against many types of bacterial infections. However, this medicine will not work against flu, colds and other infection caused by viruses. Using antibiotics like Cefaclor when they are not needed may only make your body resistant to the bacteria and may increase your risk of getting an infection later.

  • Inform your doctor if you are taking any other medications including prescription and non-prescription drugs, vitamins, and herbal supplements.
  • Antibiotics like this can sometimes decrease the effectiveness of birth control pills.
