Did anyone have vertigo from taking naturthroid 65 mg . My doctor recently switched me but just before my period I got extreme vertigo that lasted about a week after stopping Naturthroid. I've been reading a lot about how low iron or cortisol could cause this but currently my feeritin is 116 and my cortisol is am is12.4 and pm is 8.2. My doc has lowered naturthroid to 45 mg but my gp thinks I should go back to 75 mcg levothyroxine. My labs (before Naturthroid) is tsh 3.14, T4 fre 1.38, reverse t3 18.5 and free t3 2.8. Any insight would be much appreciated. By the way I did often get light headed before my period on levo also.
Thanks so much,
