It is a mixture of dex and something else. If you want to e mail me privately, I will try to find out the mixture from the dr. He is totally in control and he is 5 and his bone age is 5. I think that he has a little belly, but he doesn’t have a puffy face or anything. If you e mail me, I will send you a picture and you can judge for yourself. Good luck. We gave him straight dexamethasone once and he was way out of wack.Christine
