How Flucloxacillin Works
Flucloxacillin is a penicillin-type antibiotic that kills bacteria by:
- Attacking bacterial cell walls
- Preventing bacteria from growing or multiplying
- Stopping the spread of the infection
This antibiotic is especially useful against bacteria that produce an enzyme called β-lactamase, which normally destroys many other penicillin medicines. Flucloxacillin resists this enzyme, making it more effective for tough infections.

- Infants and Children: Doses are usually taken four times a day (every 6 hours).
