You need higher FT4 to raise FT3. It is low FT3 which causes hypothyroid symptoms. Ask your GP to raise dose. The goal of Levothyroxine is to restore the patient to euthyroid status. For most patients that will be when TSH is 1.0 or lower with FT4 in the upper range. FT4 needs to be in the upper range in order that sufficient T3 is converted.

You don't need to reduce your Levothyroxine dose because FT4 is low. I would start with a quarter tablet of 25mcg T3 (6.25mcg) to see how well you tolerate it. You can take it with your Levothyroxine. If all feels well you can increase to 2 x 6.25mcg doses. The second dose can be taken at bedtime. Hold at 12.5mcg for 6-8 weeks and have a thyroid test including FT3 before increasing further.
Adding T3 will suppress your TSH which many GPs consider is a sign of over medication and you may have battles about reducing dose.
Thanks for the advice...do you think my weight will go down once I am on t3...I am 4 stones overweight and have high blood pressure sleep apnea etc all probably caused by weight gain?
