Flucloxacillin is a beta-lactam penicillin, active against beta-lactamase producers like S. aureus. It's chosen against Gram-positive bacteria, to counter those that procuce b-lactmase (which attacks pennicillin), and for infections that resist pennicillin. That said, unless you know that your infection requires these features, I'd not start with this med. Ask your doc. If your infection isn't a Gram-positive bacteria, this won't work at all.
