my daughter was on hydrocortisone since birth, the dose changed as she grew which often change from 1/2,1/2,1/2 then to 3/4,1/2,3/4 after a year they could not get her levels right so have now changed her to prednisolone 2tabs (1mg per tab) am and 3tabs pm the trouble is she complains alot about headaches lately so I will mention this when we next go to the hosptial. she was on hydrocortisone for 8 years.
