Dextromethorphan 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!"

Dextromethorphan for Cough "Took Robitussin DM cough and chest congestion DM for a persistent cough. Took 2 doses, and my stomach is twisted, and I have bad diarrhea. Took my cough down, but I'm so sick to my stomach. Need to stop taking it to go back to work tomorrow."

Dextromethorphan for Cough "On the wee early hours of Sept. 12, 2020, I ended up in the ER after taking the recommended dose for an adult (10 ml) of Delsym. This cough syrup made me violently sick and caused me to pass out. Long story short, I ended up with right side facial fractures and right shoulder area pain. I've never in my entire life ever had a drug reaction until this. It caused me nausea for 2 days that followed, weakness, and confusion. I can't believe this product is allowed to be purchased OTC. It is toxic and should have a warning label on it. I hope others don't go through what I did."

For Cough "They should make a combination product with Imodium. I greatly reduced the cough but gave me the worst explosive diarrhea for hours. I just gave in and took Imodium and am finally feeling remotely normal. Just in time for the cough to return. Sheesh."

Dextromethorphan for Cough "Took this for cough last night and made my stomach hurt almost instantly, then woke up to horrible loose stools and stomach cramps. It has been 24 hours, and I am still in pain. It may have helped the cough slightly, but this is way worse!"

Dextromethorphan for Cough "My six-year-old daughter is an asthmatic, and the coughing she does while having a cold or flu tends to trigger it. I wanted to try a cough medicine just for bedtime to help her sleep comfortably without coughing spells. Sure enough, Delsym did the trick! I had tried Mucinex and several others for children, but felt they only made it worse. Within 35 minutes, the coughing had stopped. I give Delsym an 8 out of 10 because it doesn't last the full 12 hours, but close to it. My daughter had no side effects as far as bowel movements, gas, or hives. Just a cured cough."

Dextromethorphan for Cough "Paid $10.00 for a 3 oz bottle. Took as directed and did not stop coughing. Only upset my stomach. Called the company and they would not stand behind their product. No return policy for the unused portion."

For Cough "Took my first dose last night before bed since I have been having a nagging cough from allergies. Helped suppress the cough a little (not completely), but I was up on and off all night with anxiety, nausea, night sweats, and of course, coughing. It is now 2 pm the following day, and I have been extremely dizzy all day and have been having very gassy diarrhea and stomach cramps. I have been stuck at home all day feeling bad. Will never use this medication again. I prefer coughing over vertigo and diarrhea."

Dextromethorphan 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 "This worked great for my husband until he gave me his cold. I used this medicine and was somewhat relieved but had extremely uncomfortable gas and diarrhea. I thought I had a worse strain of virus and took the medicine again the next day. Within 45 minutes, my stomach problems that had quit the night before returned with a vengeance. Dextromethorphan was the only ingredient I haven't used before without this reaction. Unless it's a new red dye allergy, I'm never taking anything with this ingredient again."

Dextromethorphan for Cough "I used this because I had a terrible cough, so I took it before bed. I was up all night, nauseous and feeling terrible. Then I threw up from this medicine. I don’t recommend this, it shouldn’t be sold if all it’s going to do is make you throw up."

For Cough "My husband had a nasty cough for days that wouldn't go away and kept him up all night. He tried a couple of different over-the-counter medicines, but his cough increasingly got worse. Someone recommended Delsym, which he tried, and FINALLY he got the best night's sleep...not one coughing episode all night!! I would truly recommend it to anyone who's sleep-deprived with a nasty cough and a worried spouse."

For Cough "Took Robitussin syrup right before bed and woke up at 4 am and found out I’d pooped the bed, and it was watery. Probably the most disgusting experience of my life. Would not recommend. Dextromethorphan definitely caused me diarrhea."

Dextromethorphan for Cough "I took this medicine for a cough so I could sleep well before a final exam. I'm now up at 3 a.m. with diarrhea, intense stomach cramps, and I'm so dizzy I can't walk. It's also impossible to sleep because of how panicked it's making me feel. I made myself worse by taking this. Beware."

For Cough "I am currently trying to get over a very nasty cold. I couldn't handle the coughing anymore, so I bought Delsym. I took it before, years ago, with no problems. It made the cough worse before it started to help. It made me drowsy. I napped and was cough-free during that time. Maybe 3 hours. Then I woke up not feeling 'right.' I started to feel hot and had some stomach cramping. I got up to go pee, and all of a sudden, it's like I lost all control of my body. I started sweating uncontrollably and started falling and passing out repeatedly. My muscles tensed up, and I couldn't move. I finally came to long enough to stand up and immediately got horrible diarrhea. I still feel totally out of it. Make sure you have someone to monitor you if you take it."

Dextromethorphan for Cough "I took Delsym once and didn't help cough, decided to try a second dose more than 12 hours later, still no help, but now have explosive diarrhea. (Not ideal when you have a bad cough!) Would not recommend."

Dextromethorphan for Cough "It's been years since I've taken any Robitussin. I should have stayed with just the Tussin. This was Robitussin DM nighttime, but has the same active ingredient of dextromethorphan. I did not have much in my stomach, so that may have been the problem. But it's been 24 hours, and I still have diarrhea, but it was worst while sleeping and waking up after it was too late... FOUR times. That has never happened to me in my life. The cough syrup was the only new thing. I've been dehydrated all day, drinking Pedialyte, and rice and bananas. At least I'm making it to the bathroom. Never again! Ugh! Remember, your small intestines are 22 ft long, so it could take 2 days to get out of your system! Not ever taking the chance again."

Dextromethorphan for Cough "Took Delsym for the first time on 02/19. I felt high, family said I was childlike. No memory. Wasn't sure what caused it. The second time I took it was 09/19. After taking it, my family said I was acting really weird. No memory of it, but I acted drunk, and my daughter took a video to show me. I was crying because my vision was blurred and also not being able to get orange juice out of the cup. I was saying I want my mom and making things out of toilet paper. They said it was pitiful. Talking like a kid, my balance was off, kept feeling like liquid was coming out of my ear. Horrible head and muscle aches. I didn't get diarrhea like others but got dehydrated. Had sleep where you wake up thinking it had been hours but also had vivid dreams. Slept 12 hours. Didn't take the cough away. My head felt like someone was squeezing it and trying to pop my eyes out. Felt like I had been drinking last night, and I don't drink at all. I know it was the Delsym, and looking up the side effects, I fall under the overdose category. I didn't take the full dose."

Dextromethorphan for Cough "I was sleeping in the recliner and coughing no matter what I tried. This worked very well. I think it might be the best 12 hours of relief I have had from coughing. Slight diarrhea but so worth the cough relief. I would take this again when that sick with a cough."

For Cough "Worthless: I haven't had the side effects listed, but neither have I come close to stop coughing. Gargling with Listerine and letting the fumes coat my throat is just as effective, and a lot cheaper, and without fear of side effects."

Dextromethorphan "My son had chronic ear infections when he was little and continues to have them every time he gets a cold. He is now 30 years old and continues to use Delsym 12 Hour Cough Syrup to avoid an ear infection. He takes a dose at night and a dose in the morning at onset of a cold. As the cold begins to subside, he stops the dose in the morning and just takes it at night until the cold is completely gone. I've told a lot of people about it, and only one person has told me that it didn't work. I have taken Delsym myself, and neither of us have experienced feeling drugged or have had the explosive diarrhea that others on these reviews have spoken of. Everyone is different as to what they can tolerate. It thins the mucus so it can drain properly and not cause the infection. I'm no doctor but just figured it out on my own years ago when I was told that it thins the mucus. I had him try it, and he has been avoiding ear infections ever since. Beats antibiotics and surgeries."

Dextromethorphan for Cough "I had a very bad cold to the point of settling in my chest. I took Delsym 12 hour to help. I couldn't believe it really worked to keep my cough at bay, but I started to have severe side effects from it. I had dizziness like I was going to blackout, heart palpitations, SOB (shortness of breath), diarrhea, and vomiting at the same time (sitting on the toilet and holding a bucket at the same time wanting to pass out from the dehydration). Never again, I'll stick with Creomulsion."

Dextromethorphan for Cough "I took it for a constant, deep barking cough. I worked quickly and well, calming my cough and allowing me to get sleep. However, it makes me incredibly drowsy - way worse than Unisom. There was also a bit of dizziness. I did not have any gastrointestinal side effects. I will use it again but only at night since it knocks me out."

Dextromethorphan for Cough "Developed a cold that just wouldn't go away and that turned into a cough. Took Vicks, Mucinex, NyQuil, but nothing controlled the cough well. Decided to try Delsym, and while it did control the cough much better than the others, I woke up in the early hours of the morning with extreme diarrhea, awful, awful cramping, and sweating to death. I literally sat on the toilet for an hour dry heaving because the pain was so bad. It was terrible. For the next 24 hours, my stomach just hurt trying to recover. I only thought I had gotten minor food poisoning, but this morning when I had just liquid bowel movements again, I decided to search reviews since that's the only thing that has changed. I am definitely going to stop taking."

Dextromethorphan for Cough "I rarely get sick, so I have very little experience with medicine. Took Delsym as directed for cough associated with a cold. Absolutely no effect whatsoever. I’m going back to tried-and-true Robitussin, despite the taste, because it ALWAYS works."
