I am only 4 months in to my thyroid journey. i was diagnosed with a boarderline underactive thyroid in October and prescribed 50mg Actavis Levothyroxine. I felt awful, ended up having 6 weeks off work through tiredness, anxiety, headaches, aches and generally feeling down in the dumps. This leveled out after 12 weeks. I then went back for a check up and my consultant put me on to 75mg and again i felt fine. This was one tablet made by Teva. However, my prescription ended and i picked up my repreat from a different pharmacy and since i have been taken it i feel awful again and am back off work. This time i have 50mg of the Actavis Levothyroxine and 25mg Mercurypharma.
I have just spoken to the doctor and he said that he cant see why i would feel any different as its the exact same dose but I am wondering if it is where i have changed brand? Could this make a difference. From reading online Actavis performs better than Teva but im feeling so poop! Dont know what to do.
Any ideas greatfully reaceived and thank you so much for your help.
