A member asked:
Does under active thyroid causes fast heart beats as well as feeling tired, there are many nodules on my thyroid and i take eurhyrox 100 that became50?

Overreplaced: Sounds like you were taking too high of a dose causing fast heart rate and fatigue. That's why your doctor lowered the dose from 100 to 50. If this was the case, you should be feeling better shortly.
