My rheumatologist has me taking both bactrim and methotrexate. These drugs are listed as having potentially fatal interactions. I've mentioned this several times to my rheumatologist but he just smiles and says "that's not a problem."

I stopped taking the Bactrim and am not having the "mock heart attacks" I was having... shortness of breath, massive chest pain etc.

Just wondering if anyone else is on this combination of meds and whether it is working.
