I "stumbled on" the thread below about "suspect" batches of Liothyronine/T3, specifically 81171 and 81377.
Having been on 200mcg T4 for over twelve years, my endo agreed to a six month trial of 100mcg Levothyroxine plus 40mcg Liothyronine (the T3 to be taken twice daily, once with the T4) three weeks ago. I took the first morning dose of 100mcg T4 and one 20mcg dose of T3 without any adverse symptoms, but about two hours after I took the evening T3 dose I started experiencing symptoms in my abdomen, arms and legs - I can only say that I "felt" the T3 working as if it was coursing through my body. No palpitations though - my heart rate stayed steadyish at 60 and temperature around 96-97F. It wore off about three hours later. I tried this regime for two more days, then changed the timing and dose of the T3 to 10mcg three times a day with the intention of slowly increasing to the full 40mcg.
Now, the batch number I have is 81171 and if these pills are not up to strength in some way, what am I to make of their apparent effect on me and do I continue with the batch I have, which was provided by the hospital pharmacy (Co-op)? I can't really do a yellow card, 'cos I've got nothing to compare them with.
Would be very grateful for any advice please.
