My rheumatologist referred me to an Endocrinologist because a synacthen test showed adrenal gland suppression. That sounded serious and really scared and depressed me, but at the same time I thought it would be good to see an expert who could sort me out. When I saw him 4 months later he said 'of course your adrenal glands have packed in because by taking 7.5 mgs of pred that is nearly twice as much as the body would normally make so there is no need for them to do anything'. He added words to the effect the glands may or may not start up again but there is no way of knowing until the dose is down to 5 mg or less. He muttered something about doctors who ought to know better than send along people like me and sent me on my way. Just thought I'd let people know.
