Miralax and heart rhythm.. maybe TMI for some

Not sure if this goes in the other general health area but it does apply to afib. Had my ablation on Thursday. Last time I had no problems resuming my regular ..bathroom regime. This time not so much. I take benefiter Friday but that blew me up like a balloon and had weird rhythms. I was thinking of starting Miralax which I have taken in the past and works great but I recall an EP telling me at one time that this messes with electrolytes and so I don't want it to push me into a bad rhythm. I am already taking tons of Mg.. was thinking of taking some 'calm' but I already had 1000 mg of Mg today. (I usually take various kinds but I'm so tired I just grabbed the 500s which I think were oxide I have next to me.). I have an appt w. my GP tomorrow. If it weren't for the instructions of no baths for a week I'd take an epsom bath-- maybe I will do that with my feet.

So my main question here-- does Miralax mess with electrolytes? I am thinking of putting a packet in a very large glass of water and just sipping on it all day so it doesn't go in my system all at once. Open to any suggestions. I am not that uncomfortable because I haven't eaten much. (when I eat I have been having weird rhythms sometimes too.). But I do have to start eating a little more as well.

The ablation went well- they found two flutter areas and I think a touch up on the fib.

A single dose shouldn't do you any harm, but I doubt if sipping it all day will do much for you. Just take it per directions.

I take Miralax sometimes and have never noticed any effect on Afib. Perhaps your EP was concerned about Miralax causing diarrhea—which would mess with your electrolytes. Note: you don’t have to take the full dose of Miralax—there is no problem in taking a partial dose according to my gastroenterologist, if you want to be cautious.

thanks Carey and Daisy. Yea I read the packet and realized they don't want it in an all day bottle of water. It does give me a headache. I think I will go with half a dose all at once... I probably sipped a quarter of a dose. Last time I had zero issues. I wish I had written down what I ate! I"m up walking around and stuff but not my usual. And a ton of naps happening LOL!
