Another update:
It has been 16 days off the prednisone and I still have the puffy face and the hives have returned. The Dr. said they could not send me for allergy testing because the prednisone would interfere with the tests for a month or 2. Wow, I had no idea this stuff can stay in your system for such a long time and I only took it for 7 days, so my heart goes out to all of you who have been on this drug for months or years. I can't even imagine what you must be going through. I was put on this drug for hives, but some of you are on it for far more serious conditions so I have no idea if it would be wise or unwise to discontinue this drug for those of you in that situation. Talk with your doctors tell them you want off and to advise another alternative to at least try. I see that the prednisone is no cure for hives it just treats the symptoms and as soon as the prednisone was stopped the hives were still there. In my case the chance of this drug damaging my body for just a moments relief from hives was not worth it. How wonderful for those who are able to tolerate this drug but for most people it seems to have horrible effects on the body. May God help you all to make the right decisions.
