Sulfates not sulfa: Polytrim (polymyxin b and trimethoprim) contains sulfates. A patient history of allergic reaction to sulfa drugs should not exclude polytrim (polymyxin b and trimethoprim) as a treatment. There seems to be no correlation between trimethoprim sulfate and sulfa sensitivity. However, one can be allergic to anything. Check with your treating doctor.
