Hi, my doc put me on Levothyroxine 75 mcg 1 1/2 months ago and I have had 2 episodes of A-Fib lasting at least 8 hrs. each time since then. Can this drug cause,or contribute to this happening? T.K.
I realize this answer is very, very late but may help someone in future.
Yes, levothyroxine can cause arrhythmias, palpitations. I hope the atrial fibrillaton episodes have resolved for you.
Cardiovascular side effects include: palpitations, tachycardia, arrhythmias, increased pulse and blood pressure, heart failure, angina, myocardial infarction, cardiac arrest.
