Hi, I was bumped up from 50 mcg of levo to 75 mcg, I took that dose for six weeks and had my tsh come down to 2.5 so my doctor decided to keep me at that dose for the next 3 months. So a week ago I tested for my tsh and it was now at 15!!! I don’t understand I been taking my medication everyday on and empty stomach 1 hour before any meal and 4. Before any vitamins... why did my tsh went back up again?? I’m now being prescribed 88 mcg I hope this brings it back down.
