Mellatonin and afib?

[Jlaine]

Does anyone really know if mellatonin can trigger afib?? When you google it I read conflicting views regarding it.

I doubt it could trigger AF but if you have AF or are taking any blood pressure meds,beta blockers or similar or are on anticoagulation then I suggest you avoid it.

Speaking only from personal experience, I take melatonin every night, and I have been in NSR for nearly three years. For me, melatonin is not a trigger.

I take melatonin each and every night ... zero issues from taking it ... in fact the one time that l was in the hospital for afib, they gave me melatonin for sleeping.

Originally I googled it and it had said it was fine. I went into another website that said if you have afib or other arythmias you shouldn't take it!?? Google is so contradictory it's frustrating. I have had some brief periods of shortness of breath in the past week after taking 2 mg of melatonin. Not sure if it's because of melatonin? It has been 3 mths since my ablation so this could still be due to that? Go figure? Thanks much for your comment!!

I have also read it is contraindicated if you are on blood thinners? Who isn't if you have afib!!lol. Very frustrating!!

Melatonin is a naturally made hormone that is regarded as an extremely effective anti-inflammatory substance, with a very favorable safety profile. ... The investigators project that patients who receive melatonin will have a significant decrease in the occurrence of atrial fibrillation after surgery.

Also read that melatonin enhances the effect of bloodthinners such as warfarin and placed? It suggest that it may also effect other blood thinners?? Who do we believe?

Many medications that we take in tandem need closer supervision or a dose adjustment but then each individual needs a separate assessment anyway maybe because of different weights etc.. Really you need to take the advice of your doctor as he knows your complete past history, diagnoses, prognosis and present treatments. If you are concerned please ask for a second opinion, you are entitled to one. If you experience unwanted side effects you should speak to your doctor immediately before taking the next dose. Doctor Google is amazing for general information and help sites are a Godsend but generally the advice is anecdotal and is often not backed up with solid, proven science so some care is needed not to get confused. My opinion is that Melatonin does not and will not trigger Afib.. At one point I was taking 35 different medications and it was unclear as to what was causing any particular reaction, if I had acted on all the advice I received and answers found on Google, I think I would be in a straight jacket ! I can sense that you are worried and feel for you, I wish you the very best, good luck.
