I have just had my thyroid function results back today and my GP is concerned because my TSH is outside of the reference range, although my FT4 has not really changed since starting on Levothyroxine in March. My private endocrinologist thinks it is fine, and has asked if I wanted a trial of combining Levothyroxine with Liothyronine. I wonder if anyone has any experience of this, and was it helpful?
Thyroid Function Tests
17/3/16 TSH 4.01 FT4 13.3 - before medication
8/7/16 TSH 0.90 FT4 13.6 - on 50mcg Levo
4/10/16 TSH 0.86 FT4 14.1 - on 75 mcg Levo
20/1/17 TSH 0.09 FT4 14.4 - on 100mcg Levo
The Reference ranges are TSH (0.27-4.2) FT4 (10-21)
If anything I was thinking I might need another increase in Levothyroxine as I still have many original symptoms.
