Have been taking Prednisone for Poison Ivy and it has been one of the most miserable two weeks of my life. Constant urination, very moody, loss of athletic muscle coordination in particular to my golf game. I've gained 8 pounds in a week, can't stop eating. I would not reccomend this drug to anyone who has something as minor as Poison Ivy. Not worth the side effects for minor medical problems. I recommed seeking alternative medications and treatments.
