Delsym (dextromethorphan) "Horrendous. Delsym did not stop my cough. I woke up at 4 AM (I had taken the afternoon before at 4:30 pM) with serious diarrhea and vomiting. The cramps that followed are unlike anything I’ve ever felt before, absolutely horrific. This medicine needs to be taken off the market. It’s been over three hours and the cramping has worsened - I didn’t think it was possible - and I’m basically writhing on my floor. DO NOT RISK THIS!!!"

Delsym (dextromethorphan) "It's does stop the coughing but the SEVERE CRAMPING, diarrhea, and dizziness are not worth it! I was 2 days in before I realized that those symptoms weren't part of my flu.... It was the Delsym! BEWARE!!!"

Delsym (dextromethorphan) "I had a dry cough and asked a pharmacist what would be the best to take. He suggested this Delsym ,so I bought it. Less then an hour later a wave of dizziness hit me. I was not sure what was going on . Then, I began to feel like I was going to vomit. I threw up from 7 pm until 8am. I had extreme anxiety, shook, my stomach cramped and gurgled . At one point I thought I was having a toxic reaction . This is hour 16 and I am still shaking, my pupils are still dilated, and Im utterly exhausted. Im not sure how its even legal to sell this OTC."

Delsym (dextromethorphan) "I'm sick and have a constant barking cough that's mostly unproductive. I read reviews on amazon to find a good OTC cough suppressant. Delsym had rave reviews. I had hubby pick up the orange. I can say that my coughing has stopped. Delsym absolutely stops the coughing. It's quite wonderful. What's not wonderful are the three bouts of explosive diarrhea I have had since taking it three hours ago. There's more to come as my stomach is still gurgling. This is the really bad stuff. Thank goodness it stops the coughing because if I coughed right now, I'd have diarrhea all over the bed. The medicine DOES stop the coughing, but it's not worth this kind of diarrhea."

Delsym (dextromethorphan) "Stopped my cough and I was able to sleep. But I was awakened a couple of times during the night with a severe diarrhea accident. I don't think I'll take again for that reason. The diarrhea past in about 12 hours."

Delsym 12 Hour Cough Relief (dextromethorphan) "I had a very dry cough & onset of dry, wheezing chest congestion. I took a capful and the cough stopped within minutes, the congestion loosened in the nose & lungs over the next 2-3 hrs. I was able to sleep and am no longer constipated. 9/10 Stars"

Delsym (dextromethorphan) "I had purchased Delsym nighttime night strength for a cold the first night it worked great the second night I got the worst pain in my upper abs, than came nausea , followed by actually throwing up and a small bout of diarrhea. I am not sure if it was the lack of food contents in my stomach or what but it was a horrible experience"

Delsym (dextromethorphan) "Took this tonight as I've been sick for 3 days with a cold/cough. I expected it to make me drowsy but it made me restless and completely unable to sleep. I came here looking to see if anyone else had that reaction. I don't think it helped me cough at all either. Now I will probably feel worse tomorrow seeing as how I didn't really get any sleep tonight."

Delsym (dextromethorphan) "I am currently taking delsym for a nasty cough and upper respiratory infection. I took the recommended dosage of 10 ml every twelve hours. After the first dose I became worse. My cough had gotten 10x worse I had severe chills bad body aches and severe dizziness to the point of not being able to sit up right. I would have gone to the hospital but didn't have a ride. I can't sleep because of the cough. I took a half dose compared to the recommended dosage (5 ml) and am having the same symptoms. Freezing, worse cough, and dizziness. I do not recommend whatsoever and will likely be going to the hospital this evening due to not being able to breathe."

Delsym (dextromethorphan) "It definitely helps my cough. But it makes me so dizzy, I feel like my surroundings are going by at 100mph when I walk. I would NOT drive after taking it. I also feel a little "out of it", but that could just be having a sinus infection. I didn't have a problem with diarrhea like some people have mentioned."

Delsym (dextromethorphan) "I took this late at night expecting it to work and I should have read the reviews first it didn't stop my cough at all and I think made it worse I ended up just sucking on a cough drop which worked better than this. It is now 5:30am and my stomach feels twisted like I'm going to vomit but I don't have anything to vomit because I haven't eaten anything and it has to be the cough syrup because I have had the cough drops before. I'm never going to use this medicine again."

Delsym (dextromethorphan) "Do not take this!!! I started taking this during the tail end of my flu because my symptoms were mainly just coughing with phlegm. It gave me nausea which I thought attributed to the flu but after taking it a couple more times I noticed I was extremely nervous with anxiety. I stopped taking it for 2 days then took it again to see if it really was Delsym causing me severe anxiety. I became super anxious right after 1 hour taking it and it took about a day and a half to wear off and I only took the regular delsym and not the 12 hour one. Please be aware!!! It did suppress my cough and thinned my mucus but I'd rather deal with the coughing and mucus than the severe nervousness I dealt with."

Delsym (dextromethorphan) "I have a hard time believing that there are so many people that are claiming diarrhea. I had no such experience. It also calmes my cough. I have IBS, which affects the bowels very easily. I have also known other people that have used Delsym and nobody has had this happen to them. It tastes better and really works. I have to say I suspect 1 or 2 people that had a bad experience have written multiple times too warn others. I hope people are going to more than one site to get reviews."

Delsym (dextromethorphan) "This is the most useless medicine I've ever taken! I have the flu so I have all the symptoms... fever, chills, aches, and congestion. I took delsym to ease the coughing and instead of doing anything, all it did was give me diarrhea and I was still coughing to the point of gagging. Thanks for adding to my problems delsym!"

Buckleys Mixture (dextromethorphan) "I have a cold. At 2am I had a persistent non productive cough. I found Buckleys Mixture in the medicine cabinet. I swallowed a teaspoonful of the Mixture and went back to bed. Next thing I knew, I was waking up at 7am. This Mixture stopped my coughing."

Delsym (dextromethorphan) "Took 5 hours ago. Still coughing. Now I am pooping as well. Came to read reviews because I don't think I could have eaten anything else to cause diarrhea. I'm hoping I don't have 8 hours of stomach issues but it's not looking good. Maybe it doesn't happen to everyone but user beware!"

Delsym 12 Hour Cough Relief (dextromethorphan) "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 0 gas, nausea, or poops from it!!! Most medicines do cause those above symptoms listed, and with this, I have none."

Delsym (dextromethorphan) "Learned the hard way that this stuff causes explosive diarrhea. I wouldn't take this if you have any plans for the rest of the day. Honestly not sure if it really even helped with my cough or if I was just getting better with time. Wish I looked into it more earlier on instead of waiting. It feels like they have added the active ingredient for miralax in a drug designed for already sick people?"

Delsym (dextromethorphan) "This cough syrup should be advertised as a colon cleanse. Fast acting! Holy moly. Within 10 minutes the diarrhea hit me like a freight train. I didn't know I had all that in me. The diarrhea was a great distraction from my sore throat. I didn't think the diarrhea was from the Delsum at first. I put two and two together when every 12 hours I took a dose it was followed by the violent emptying of my being. I did feel immediately better after the trips to the bathroom."

After the nauseousness passed, I was straight tripping. I can’t believe this stuff is legal. Don’t take it unless you gave absolutely no other choice whatsoever."

Delsym (dextromethorphan) "I have to admit that this is one of the most effective cough suppressants I've ever taken. Unfortunately, I seem to experience side effects from it, thankfully not rampant diarrhea like many people seems to be experiencing, but I still can't take it anymore. Delsym has a commonly reported side effect of dizziness, but what I experience feels more like dizziness meets an acid trip. It's extremely unsettling and didn't happen the first time I took it; more like the 10th. But it happens every time I take it now. Bummer"

Delsym (dextromethorphan) "I had a long term chronic cough a few years back & was buying everything on the shelf, nothing worked. My hubby asked the Pharmacist what he would recommend & he said Delsym the orange stuff, thought it was expensive but bought it. I immediately stopped coughing. Well here I am coughing again for a long time & finally broke down & bought some, no more cough with one dose & may take a dose today. Thanks for this great product."

"DIARRHEA. Remember that word, because if you take this stuff, you will be suddenly awaken during the middle of the night and forced to wreak havoc on your toilet bowl. I just blew up my toilet 45 min ago and am getting ready to pay it another visit as I write this. If you are reading this review, take my advice: use something else. My cough was bad, but I would have gladly kept it if I knew my butt was going to turn into Niagara Falls."
