Hi, I went to collect my prescription for my Levothyroxine and when I looked at the script the GP has increased the dose from 125mcg to 150mcg. I have no idea why and my TSH is normal with my 2 thyroid hormones and thyroid antibodies high! I mentioned the changed dose to the practice's receptionist who asked me if the GP had spoken to me about changing my dose and I said no. I find this most odd, why would the GP suddenly change my dose when she has said I am on the correct dose? And why change it just before my thyroid blood test is due?
