This has come up in several past paper questions. For instance, Question 13 from the first paper of 2010 asks about antibiotic choices for MRSA.

Antibiotics for MRSA

You're not resistant to everything yet, you bastard.

A good article on the antibiotic management options for MRSA lists an entire arsenal of drugs which could be useful. Here they are, with links to articles about them.
