For Cough "I get bronchitis at least once or twice a year, and this is the only medicine to help my cough. My coughing keeps me up at night, my ribs hurt, and this medicine gives me some relief. I get no gas, nausea, or poops from it! Most medicines do cause those above symptoms listed, and with this, I have none."

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 "Did absolutely nothing to alleviate my cough. And now I am feeling slightly nauseated. I actually think my cough was better before taking it, as at least the hacking was removing phlegm. Now it's a useless dry cough that is just as painful to my poor abused ribs. Thankfully, I haven't noticed any warning signs of diarrhea. Hopefully, it'll stay that way. Overall, this product was an unsatisfying waste of my money and time."

For Cough "I started taking this medicine a week ago for a sinus infection-related cough. I noticed more anxiety and doing a lot of running to the bathroom. I thought it was from just being sick and taking an antibiotic. Tonight I took a dose, and within 30 minutes, I experienced extreme nausea. I found this site, and it all makes sense now! No more Delsym for me!"

For Cough "Delsym 12-hour cough medicine should be avoided at all costs. I wish I had never taken it. At first, it seemed to work, but then came the diarrhea, nausea, and dizziness. I had trouble sleeping while taking this product. After 2 doses, it triggered a histamine reaction as well. Before taking this product, my only ailment was a lingering cough from having a cold. After taking Delsym, I'm still dealing with the cough, but now I also have diarrhea, and all the symptoms that come with full-blown allergies. I can't wait until my body completely purges this horrible product from my system."

For Cough "I do not recommend the use of Delsym 12 Hour Cough Relief. It was recommended to me by a pharmacist to help with a COVID cough. I have high blood pressure, and according to the pharmacist, this would raise BP. At 11:00 pm (bedtime), I took the prescribed dosage. At 1:30 am, I awoke with severe nausea, stomach cramps, dizziness. A few minutes later, diarrhea with numerous trips throughout the night. I sipped on water and tried soda crackers to help with nausea. My blood pressure was 200/100. For 12 hours, I was extremely ill. The next day, I went to urgent care. The diagnosis was side effects from Delsym 12 Hour. I believe this drug should come with warnings of these side effects and be removed as an over-the-counter drug."

For Cough "I took it for nasal congestion because, for some reason, that’s what I thought it was for, and it was the orange syrup version. It cleared up my sinuses pretty much 100%, so I’m really impressed with it. I must be lucky because I ended up taking half the bottle (over a long period of time) and didn’t experience any nausea, whereas a lot of people say they were vomiting with only one dose (by the way, the amount I drank is safe because it was pure dxm HBr)."
