http://www.medications.com/effect/view/22356 I took prednisone for 6 days - weaned off. I took it for poison ivy. Ended up with a rash/hives worst than what the poison ivy did. I took this drug about 8 years ago with no ill effects. Now at 48, I am swollen and itchy ALL over my body. While on it, Sun, 22 Jul 2007 15:09:58 -0400 http://www.medications.com/effect/view/22356?item=841 I do not know how long the side effects will last. I would like to know what was your starting doseage and how were you tapered. Good Luck. http://www.medications.com/effect/view/22356?item=841 Fri, 18 Apr 2008 12:04:26 -0400 http://www.medications.com/effect/view/22356?item=7399 Prednisone for 6 days doesn't have to be weaned off.
