Can Prednisone Casuse Low TSH Results?

11/15/2006

Question:

I have been on prednisone for many years for treatment of lupus. This month my TSH turned out to be 0.197. Doctor says I have hyperthryroid. Could it be from prednisone or not?

Answer:

High doses of prednisone can decrease TSH levels at first, but eventually the body escapes from this effect and TSH levels return to normal. I suspect that your low TSH is not from your prednisone.
