Gvhd symptoms and conditions

I had a kidney transplant a year and half ago, and had to take Prednisone as one of my post-transplant med's. I was on it for about 2 months and I went through a lot of the same side effects mentioned by other people, increased appetite and weight gain in odd places, sleeplessness, and acne. Then recently I had an allergic reaction to an antibiotic and was again prescribed prednisone for three weeks, but this time the acne is so bad it looks like a rash, and it's all over my back, chest, neck especially, and on my face. I can deal with it because I realize it's what I need to do, and I am grateful that there is a drug that can treat the symptoms from the allergy, but I am wondering how long it will take for the acne to clear up once I finish the 3 weeks? Does anyone know how long it takes when you've been on it for that amount of time? Any thoughts would be helpful. Thanks.

I've been reading the past postings and so far have seen nothing about adrenal gland failure. My husband was on 60 mg a day since Nov. 05 (for GVHD) and they have been weening him off since. He was down to 5 mg and he just seemed to crash, no energy, panting when going upstairs, just plain tired. They tested his adrenal glands and I have read that prednisone can atrophy them so now they have upped the pred to 7.5mg which is what these glands put out usually.
Has anyone had this or know what drugs they use to kickstart the glands?
He also has the moon face, buffalo hump and budda belly but he exercises every day because of the osteo and muscle wasting.
