Have been on T4/T3 combo since March. Worked up gradually to 100mcg levo with 20mcg T3. Was fine for about a month then hypo symptoms reappeared so I upped the T3 by just 5. The next day I had massive palpitations and my knee jerk reaction was to decrease the levo. these blood results were from tests while taking 50 T4 and 20 T3
T4 14 (7.8 - 21)
T3 8.9 (? - 6)
I am now taking beta blockers to calm my heart down. I hold my hands up to messing with the dosage too quickly. My consultant wants me to get back to 100 + 20 where I felt well and doesnt seem concerned that the T3 is a little over range. Does anyone think the uncomfortable heart problems are thyroid based? This happened once before when massively overdosed with levo.
