dextromethorphan for Cough: Works very quickly after taking it. However, supposed to last 12 hours and after about 5 hours I was coughing again and couldn't take anything due to the medicine still being in my system (12 hours wasn't over). I also had to go to the bathroom (upset stomach) after taking but I am not sure if there is a correlation. I do think it works much better than any other over the counter cough suppressant that I have tried with this cough, and this was a very terrible cough!
Delsym (dextromethorphan) for Cough: Works really well, like Tussinex without the codeine. Tastes better than other cough medicines too. Non drowsy, but also didn't make me jittery so I could take it and sleep. Closest thing to Tussinex over the counter.
Delsym (dextromethorphan) for Cough: I actually came on the site to see if severe diarrhea was a listed side effect. I have taken other products with the same active ingredients and not had this happen. Twice I have taken Delsym, which I buy for my kids, and had severe diarrhea. It must be an sweetener or thickener that they use. That being said, I haven't coughed in hours.

Delsym (dextromethorphan) for Cough: Although it did stop the coughing, I had a bad allergic reaction. My body started itching, my tongue and lips swelled. And when the itching stopped, things felt weird.
dextromethorphan for Cough: This medicine works for cough, but as the other reviewer said, it can have side effects like all medications. In my case, it makes me hyper. My 6 year old daughter had a bad dry cough and I had given this medicine to her. It turned her into "The Great Cornholio"! My child was talking so fast, I don't think she could even keep up with herself. Her Pediatrician was contacted, and they prescribed her a liquid that contained guafenesin and codeine. She is borderline ADD, and the Pediatricians office said that this medicine sometimes effects kids this way when they have ADD or Hyperactive. Anyway, my point is if you have any diagnosed condition, or suspect that you have a condition, look to see if OTC medicines will affect you in any different way.
