Was taking Levothyroxine 100 mcg for 10 years then started to get palpitations, missed beats and landed up in A&E with Atrial Fibrillation. Diagnosed with T4 toxicosis and taken off T4 for
short period where I immediately felt better. IBS I had had for years cleared up and I was less anxious. However my TSH
went up to 44!
Now seen by Endocrinologist who has prescribed 25mcg Levothyroxine and 10mcg T3 but still feel exhausted. Would I be better on NDT or does T3 take time to work?
