Flucloxacillin ( INN) or floxacillin ( USAN) is a narrow-spectrum beta-lactam antibiotic of the penicillin class. It is used to treat infections caused by susceptible Gram-positive bacteria. Unlike other penicillins, flucloxacillin has activity against beta-lactamase-producing organisms such as Staphylococcus aureus as it is beta-lactamase stable. However, it is ineffective against methicillin-resistant Staphylococcus aureus (MRSA). It is very similar to dicloxacillin; they are considered interchangeable. While no longer used in the United States, Flucloxacillin is supplied under a variety of trade names in other countries, including Floxapen ( Beecham, now GSK), Flopen ( CSL), Staphylex ( Alphapharm), Softapen (Rephco Pharmaceuticals Limited), Flubex (Beximco Pharmaceuticals Ltd, Bangladesh), and Flupen (for state use only in South Africa).
