Minus, 25mcg is insufficient to treat your thyroid as shown by the increase in your TSH. Your GP should increase your Levothyroxine. FT4 is in range but a bit low and the dose increase should improve your FT4.

FT3 is rarely tested unless TSH is suppressed <0.04.

Funny you should say that clutter on the results I.e tsh 6.2 abnormal top of the letter said expected results take no further action. I have just rang my drs surgery and asked for a Levo increase- he will ring me back wed.seems my Dr Is happy with my results- but I'm not as I still feel overly tired, low mood' pins and needles in fingers.


Minus, if your GP doesn't increase your meds please see another GP at the practice for a second opinion. TSH should be just above or below 1.0 when on meds. Scroll down to Guidelines and Treatment Options to read Dr. A. Toft's comments in Pulse Magazine

Email for a copy of the article if you want to show it to your GP.


I went to drs this morning, l asked to see different Dr and she didn't hesitate in putting me up to 50mg. She agreed that 25mg was too low and said I could go up much higher with Levo, regarding the tsh 6.2. Feel better and will def be changing GPS now.


Thank goodness, Minus. I think you will need more than 50mcg but incremental rises are usually 25mcg. Have another blood test in 8 weeks, remembering to have it early in the morning before you take your Levothyroxine.


Pins and needles in your fingers could be carpal tunnel, which often improves when you are properly medicated, or it could be B12 deficiency. Have you ever had B12, Vitamin D and Ferritin levels checked? Lots of us hypos are also low in these vitamins/minerals.
