Flucloxacillin Capsules contain flucloxacillin, a penicillin-type antibiotic used to treat bacterial infections, including impetigo — a contagious skin condition that causes red sores or blisters. It works by stopping bacteria from building their cell walls, which kills the bacteria and clears the infection. Flucloxacillin is effective against Staphylococcus aureus, a common cause of impetigo.

The medication is usually taken on an empty stomach, either one hour before or two hours after food, to ensure better absorption. It’s important to complete the full prescribed course, even if symptoms improve early, to prevent the infection from returning or becoming resistant to treatment.
