Can you get to a MDA clinic near you...correct me if I am wrong but I think they are free. Or go to the emergency room. Your genius of a neuro I hope at least did liver function blood test and the blood test to check if you can take Imuran. I forget the name of the test but it should be done prior to starting Imuran. Again, you sound sick and if you can't swallow go to the emergency room.

TPMT is the name of the blood test.
