A few years ago I got a HORRIBLE case of poison ivy. So bad I went to the doctor for help. He gave me prednisone, a steroid, and my life has never been the same. I am now lactose intolerant, have a weight problem that is difficult at best and never-ending at worst. I developed stomach ulcers and have had a terrible time healthwise all the way around. I know it is because of the steroids. And though I did go to the doctor on my own, I wish I had been better informed of the side effects.
The prednisone also made me break out in a rash everywhere the poison ivy had missed. I was miserable for nearly two months and have a strong phobia of anything that is green and leafy even resembling poison ivy.
Editor’s note: the Wikipedia article on Prednisone lists quite a few major and minor side effects.
