well, there are really three drugs that could help here - vancomycin, gentamycin, and tobramycin. vanc is the most brutal of the bunch. if vanc is chosen, it MUST be given IV b/c the actual vanc molecule is too large to be absorbed through the "gut", the large molecule is also the reason that vanc is incredibly painful during IV administration. have they actually cultured her puss to be sure that it is MRSA? if you are not satisfied with her treatment, i would have her moved. but do this understanding that at 100 years old, her body is not equipped any longer to take an extremely aggressive "cure". if it hasn't been done already, i would insist on an infectious disease specialist being called in. good luck and i hope your granny gets better.
