For a local skin MRSA infection, draining the skin sore is often the only treatment needed. However. for more serious
MRSA infections,
antibiotics that may still work include vancomycin, trimethoprim-sulfamethoxazole, linezolid, tetracycline, or clindamycin. In your case, if a culture and sensitivity test was done and it showed it is sensitive to a particular antibiotic, this may treat the infection.
