I was diagnosed with A-Fib in Oct. 2021 I was on Multaq from then to March 2022.
My cardiologist told me to stop it since I was asymptomatic,
I just stopped it and had no problems related to the drug.
As an aside I just a few weeks ago tried Multaq again.
I always had a low resting heart rate in the 50’s and for me normal and always felt good.
Multaq as with most anti arrhythmia drugs lower your heart rate,
Multaq, like you puts me in the 40’s and I do not feel good.
Multaq as with other anti arrhythmia drugs (unfortunately for me) do not seem to really help with the A-Fib.
Hope this helps.
