Multaq questions

Posted by alan56 @alan56, May 5 9:01am

I am 56 years old. I was diagnosed with Atrial Flutter early January 2024. Successful cardioversion(cv) in February. Prescribed Multaq (400mg twice a day) after cardioversion(cv). Was on Diltiazem and Pradaxa prior to cv. No longer on diltiazem or blood thinners. I use an Apple watch every day. My resting rate for the last month was 42-49 bpm. I have had no recurrence of the flutter since cv, but the low rate concerns me and I want to stop taking the Multaq. I do exercise regularly and my blood pressure runs about 135/70. I don't have any recognizable symptoms from taking Multaq except the low heart rate. I'm really interested to know if anyone had similar response to this drug? I have an upcoming appointment with the Cardiologist and want to discuss coming off or discontinuing Multaq. Any advice would be greatly appreciated.

From the foregoing, it appears that one of the possible side-effects is bradycardia. Technically, HR less than 50 is considered to be in the range of bradycardia, and you're there. However, this is judged on a case basis. If you're an athletic person and have a history of low resting pulse, then maybe there's nothing to change and you might be better off sticking with the Multaq? This is something to run past the prescribing authority.

Thank you for your response. The hardest part for me is not knowing what my resting HR was before the flutter. I look at the side effects of the drug and shudder. Thanks again!

Remember, though, that these side effects are only those most frequently reported, and the insurers and practitioners all want to avoid lawsuits...so full disclosure. Drugs in widespread use, as Multaq is, are usually well and universally tolerated. Not always, not by everyone, and we're all individual cases who basically have to try it on for size to see what fits. Doctors have little option but to encourage you to see what works, at what dosage, and for how long it works trouble-free since sometimes a cumulative bio-availability in your system brings on unwanted side effects. The doctors do take into account your history, genetics if that info is available (some genes make some drugs intolerable due to metabolic differences), and the stage of your condition, not to mention other drugs you're taking that might interact with the new proposed drug adversely.
