Multaq and kidney/liver problems?

I have been on Multaq for about two years since my ablation at Duke that was not quite successful. I have not had obvious side effects but my creatine level today was 1.2. My EP is monitoring kidney functioning and liver functioning and my BUN slightly elevated too. I just sent Dr. Bahnson a note about my internal medicine doctor's lab work today.

Does anyone know of folks having serious liver and kidney conditions (or other serious side effects) arising from Multaq? It is supposed to be the mildest and perhaps safest but... I have been dehydrated because I play tennis 4 times a week in Durham, NC and it has been HOT. Taking electrolytes, 1000 mg magnesium (the good kind!), potassium, etc. but I had played today for two hours prior to the lab work. Hoping that is the case!

I don't know of anyone who has experienced such symptoms, but apparently it is possible according to drugs.com, which I consider to be a reliable source. Here is the report, but I would caution you about over-interpreting it. I think your dehydration almost certainly explains the issue.

I had abnormal kidney and liver numbers while taking Multaq. Both my primary care and Natale’s lab brought this to my attention. They resolved after stopping Multaq.

My liver function tests were off the charts just a few days after staring Multaq - no other symptoms that I can recall. Needless to say I stopped immediately. Same tests were normal a few days later.

Thanks all for responding. I am getting another lab in a week and not after tennis in 90 plus degrees. Haven't heard from my EP yet with the holiday weekend but sounds like monitoring, which he has been doing is very wise. Rather scary to learn two of you actually did have serious enough liver and/or kidney effects to stop this medication. Perhaps Dofetilide would actually be safer. Or a second ablation....

Hi , I was just prescribed Multaq. I will definitely keep an eye out for my labs. Do you mind sharing what magnesium you are taking . Thank you .
