I always use products with dextromethorphan when I have a cold and I've had no AFIB issues. Everyone may have different triggers but this is not one of mine.

I take only an antihistamine that has loratadine, I buy the Kroger brand non drowsy, Anything with pseudoephedrine or dextromethorphan makes me very jumpy and causes palips for me. I also use Eucalyptus oil in a vaporizer. It does help...... Sorry you are feeling so bad

thanks guys.

Yes I also use Loratidine as an antihistimine, which if fine and dr. approved. I thought that dextromethorphan was a cough suppressant. which is what I want. Pseudophed etc. are stimulants; I can't have that
!

FYI check out the first line, I would ask my doc for something......... Hope you feel better soon!

Dextromethorphan side effects

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Stop using dextromethorphan and call your doctor at once if you have any of these serious side effects:

severe dizziness, anxiety, restless feeling, or nervousness;
confusion, hallucinations; or
slow, shallow breathing.
Less serious side effects are more likely, such as stomach upse

Friends, hear my tale of woe. I brought this drug to my doctor and asked if it was o.k. (brand new g.p. for me). He said it was fine for my condition. I have pneumonia right now, but just started a round of penicillin. I had an accelerated heart rate several nights earlier but atenolol brought it down and I was running smooth and pretty. My fever breaking further helped. I could see the finish line! then, Wham! within a minute of taking this drug, I went into afib, pretty bad. This time, the atenolol hasn't stopped the irregular beats, so far. I'm probably headed for a cardioversion later today.

I read Daisy's comments AFTER taking this horrible drug. It's so obvious. Had I read these comments first I never would have taken the drug, even with a g.p.'s blessings.

p.s. dextromethorphan is a cough suppressant, not a decongestant. I can't fin a way to edit my topic line however.
