Can anyone advise? My doctor has prescribed both hydrocortisone (cos my adrenals are knackered) and Erfa Thyroid together and has instructed me to take them together from day 1. I have so far not taken ANY meds. I would have thought it would be better to start the hydrocortisone BEFORE starting the Thyroid, particularly as the doctor said he thinks my main problem is adrenals not thyroid. I so want to do this right; I can't ask my doctor as he is over 300 miles away and will only communicate (not very well) by email - he will also I am sure only repeat what he said before. Also, if I feel better once on the cortisone, is there a need to take Thyroid too, as surely once the adrenals work then the thyroid will follow?
