Brand name: Floxapen
Flucloxacillin is a narrow spectrum antibiotic used to treat infections caused by beta-lactamase-producing staphylococci. Unlike benzylpenicllin, it is effective in treating infections caused by penicillinase-resistant staphylococci.
It is most often used to treat otitis externa, impetigo, cellulitis, and osteomyelitis. Flucloxacillin is also indicated in the treatment of staphylococcal endocarditis.
Typically 250-500mg 4 times a day.
Flucloxacillin is well absorbed from the gut and should be taken at least 30 mins before food (unlike most other antibiotics).
