It's a double edged sword- if you've never taken pred before, you will LOVE it. It will put you into remission quickly, you'll feel great. You won't sleep much though! It's when you stay on it for long, or can't come off without flaring, then it starts to get nasty. Yes, the side effects are not so good- moon face, buffalo hump, acne, insomnia, thrush.... The worst one for me was thrush, I got it every time right off the bat. But it's easy to treat with an oral solution. The other side effects I also got, but not until I started to come off prednisone. My first course was a magic bullet, I loved it. My third & last course sucked big time- it didn't do anything for my
UC & I got all the horrible side effects.
