For Cough "I have taken Delsym ever since I was young (for colds). I have asthma, so a cold isn’t just a cold for me, but every time I have taken it has resulted in nausea, vomiting, extreme dizziness, fast heartbeat, and shakiness for about 2 days. I later learned that the ingredient called dextromethorphan was causing this. Anytime I take anything with this, it happens. Idk if I’m sensitive to it or allergic."

For Cough "I just took 10 ml Delsym for my chest and dry cough, adult strength. And 10-15 minutes after taking it, my heart started racing, and it scared me. I called the pharmacist about the heart pounding, and she stated that was a side effect. Here I am, feeling like I ran a mile and back, lying in my bed. I am not happy with this, even though I'm not coughing. I would caution anyone who takes this medication to be careful. I don't know how long it will be before it wears off, but I'm ready to feel relaxed again. Ugh, December 20, 2020"
