I would appreciate any assistance to understand the below statement. Does it mean if you have Adrenal insuffiency, you should not be treated with levothyroxine. What if you have to take levothyroxine because you have had a thyroidectomy 17 years ago and you can't live without a medicine?
Levothyroxine is contraindicated in patients with uncorrected adrenal insufficiency since thyroid hormones may precipitate an acute adrenal crisis by increasing the metabolic clearance of glucocorticoids [a too-rapid withdrawal of cortisol]. Patients known to suffer from adrenal insufficiency should therefore be treated with replacement glucocorticoids before starting any Levothyroxine sodium treatment. Failure to do so may precipitate an acute adrenal crisis when thyroid hormone therapy is initiated.
