Hi all, I had GPA for 11 years now and have been on Mycophenolate and 5mg of Prednisolone for some years now. At clinic yesterday they want to stop my Prednisolone . I am to have a blood test to see if my body is producing its own. If so it will just be stopped without reducing it. If not then they will put me on hydrocortisone which they say has less side effects. Has anyone had this happen to them? Reading the side effects of hydrocortisone they seem very similar.
