What about a swollen tongue as a result of predisone... 4 x daily for five days?

Call your doctor and report this asap. Prednisone is a steroid and should NOT be stopped suddenly unless the doctor tells you to. You should let the doctor know you have had symptoms of a reaction and let the doctor tell you what to do. If your tongue swells anymore, or you are having trouble breathing, go to THE ER.

You probably are having an allergic reaction. You should call your doctor.
I was given predisone for posion ivy break out a few years ago. I don't feel like it really helped at all, but then again I wasn't prescribed to take it 4x a day. For me, I think the sores pretty much cleared up on their own with the help of some hydrocortisone ointment for the itching.

Signs of an allergic reaction, including unexplained rash, hives, itching, and unexplained swelling. are some of the side effects of taking Prednisone, if the become too bothersome, please seek medical advice from the doc who prescribed the med, take care & be well!
