I'm 26 years old and broke out in a horrible rash back in June. It was basically all over my upper torso, arms and my legs. I went to see a dermatologist and got a high prescription of Prednisone (40mg/day). The rashes went away, but I had many side effects. I gained 10 pounds in a few months (and it's hard for me to gain weight due to my high metabolism), my cholesterol shot up from 170 to 219, I was having mood-swings and feeling depressed, I was having dizzy spells, and it seemed like I was eating everything in sight. Now that I am off Prednisone, my cholesterol is back to normal and am not feeling depressed or having mood-swings. I am still waiting and working on losing the extra weight which does not seem to go away, esp. around my stomach area. I still feel light-headed at times but it's bearable. I hope there is a better drug or solution out there in case of another break-out. I do not want to go through that again.
