I had a severe allergic reaction to a Sulfa drug that I was taking to prevent infection . I had a skin cancer removed from my nose. As a precaution I was given Sulfa. I became very ill. I ran a high fever ( 103) . The Doctor said it was not from the Sulfa drug. Advised to go to Primary Care Dr to check for a Virus ( flu) . I ended up in the Emergencey Room at the Hospital the same day . By then I had broken out in a red rash all over my body. They immediateky asked if I was on Sulfa drug. I was given a steroid shot for the rash & tylenol for fever ;also prescription for Methylpred. It worked great. Now, after 2 months, I believe I am having side effects from the Methylpred. The instructions were to stay out of the sun whild taking Methylpred and for a while after the 6 days. It has been 2 months . When I get in the sun I break out in a rash that feels, looks & acts like a sunburn. I even peeled. I am 78 yrs old. I do not normally take drugs, so I had no idea I would be allergic to anything. The Pharmacy Dr. does not believe this side effect could last 2 months. What do you think? Ed
