I have been on Predisone for a couple of years now. I am battling my weight, and I am really wanting to come off of it. My doctor said no again yesterday. I have a moon face, but the weight gain did not start coming on until 3 months into taking predisone. It can be every helpful, and I was better for sometime, but I have just gotten fat for the first time in my life. I am down to 5mg, but I am not seeing any weight decrease yet. There are special precautions for starting and stopping predisone. I had surgery last year, and I had to be injected with steriods ect before I was operated on.
