Prednisone
"Prednisone works well when it needs to, but the side effects are horrible. I'm only 16, had my first flare when I was 14. I ended up on prednisone for almost 6 months while trying to find a treatment that worked for me (Asacol, then Remicade, etc.) and it did keep my flare in check. While I was on it, I had a huge appetite and ended up gaining close to 20 pounds. My face also got swollen, and I grew hair in some gross places like the back of my neck. After I was off it I slowly returned to my normal weight and most of the side effects disappeared. The side effects are a bummer, but other than that it does it's job."
