In my case, after a long down time that was turning into a depression episose, the doctor suggested I try it for awhile to preclude getting onto the heavier Prozaz. This has nothing to do with the thyroid question but it's been the only thing I've taken for depresstion (although mild) and it did help me. Who know, maybe the placebo affect. Mike
