Sulfa drugs: Mrsa means methicillin resistant staph. Aureus. Many infectious disease specialists become very concerned about this. The bacterium simply is resistant to this particular antibiotic. In my experience most of these organisms are sensitive to sulfa drugs. Incidentally, vancomycin is not given by mouth. I do not think it is dangerous. Get a culture and sensitivity and be placed on correct drug.

See below: If you have an MRSA sinusitis you are correct that oral vancomycin is not absorbed and would be totally inappropriate treatment. Oral Minocycline or septra (sulfamethoxazole and trimethoprim) which achieve good levels in sinus and nasal secretions and which are effective for 90% or so of MRSA strains would be my recommendation. I would also use Bactroban Nasal ointment for decolonization.
