Hello. I have been suffering with hypothyroidism type symptoms for ten years but never had a thyroid condition diagnosed officially. My blood tests always come back "normal" although at the lower end of the normal range. My latest results are: T3 = 4.0, TSH = 4.3, T4 = 13. I am so desperate that I am thinking of self medicating with Liothyronine 5mg a day and see what happens. I am also taking prescribed Venlafaxine 75mg and Ferris Fumerate 200mg a day. Would there be any adverse reactions with the Liothyronine? Grateful for your advice.
