I have been on Diovan for a couple of months. I am allergic to sulfa drugs and for the past 4 days have been experiencing tremendous itching on my upper back, face, arms and now it is spreading on to my legs. My chart at the doctors office says what I am allergic to and I have told my doctor several times but she told me Diovan did not contain sulfa and if it did it had very little and would not effect me. I am off dairy products and I don't know what is causing this terrible itching but I cant stand it any longer. I think I will discontinue this med for a while to see if my rash goes away and the itching stops. It is unbearable.
