It's only necesssary to reduce Levothyroxine before adding T3 when you are optimally medicated on Levothyroxine. Your last blood results are not optimal and you were undermedicated.
TSH 5·76 mu/L. ( 0·35. -5·5 )
T4 15pmol/L. ( 9 - 23 )
T3. 4· 1 pmol/L ( 3·5 - 6·5 )
You might want to acclimate to T3 by starting on 10mcg daily for a week. If you don't have symptoms of overmedication ie jitters, palpitations, anxiety, loose bowels etc. increase to 20mcg.
It's usual to notice slightly increased heart rate, raised pulse and perhaps slight palpitations an hour or so after ingesting T3 but they should all calm down within another hour. If they don't, skip the next dose until you have settled. T3 is out of the serum in 6 hours so any side effects won't go on for long.
