For Cough "Uhh, I took this medicine for a severe cough because of seasonal allergies. I was taking Mucinex, but it wasn't as effective immediately. So, I asked my mom, who also deals with allergy issues, and she gave me this Delsym. It did, in fact, suppress my urge to cough but with major repercussions. It is now 10 pm, 12 hours after my first dose, and I can't stand myself right now. I feel so disoriented that it is hard to focus on this message, but it is important that I share my experience so I can save some of the trouble this way. I have an anxiety disorder, this is important for others like me so they know that this medicine has made me feel so incredibly bad that I have serious, serious dark thoughts about myself. I just want to stop this unexplainable, very terrible feeling throughout my entire body and brain. I hope this horrible experience will end soon. I'll be sure to update on how long the effects last. So far, 12 hours and counting..."

For Cough "Absolute nightmare. Do not take, for the love of God! I took it for an upper respiratory cough at around 4 pm, and the nightmare began shortly after when I got the chills so bad I couldn’t stand up. I was sweating bullets but freezing cold. After that stopped, this poison passed me out, at which point I had the most extreme nonsense nightmares I’ve ever had in my life. Atop all this, I coughed and coughed and coughed to the point of gagging. This medicine is poison. Wouldn’t recommend it to my worst enemy. Such an astronomical waste of money, time, health, and sleep. I poured the remainder down the toilet and felt bad that the water treatment facility now had to deal with this absolute toxic waste."

For Cough "I made the mistake of taking this medicine before going to bed. I woke up in my own excrement. Seriously, this is no laughing matter. It was like something out of a Dumb & Dumber movie. I had a raging case of explosive diarrhea. I feel sorry for the poor souls who don't use at least 3-ply toilet paper. Food went right through me like fat people go through Twinkies. I would only recommend it if you take a lower dosage than the recommended one."

For Cough "Took this as a cold medicine because I can't stop coughing. Was all fine and dandy and went out to dinner. Halfway there, I had to stop because I felt gurgling in my stomach. Sure enough-diarrhea. I should have listened to the reviews-do NOT take this medicine."

For Cough "I took the appropriate dose of Delsym, and 30 minutes later began hallucinating. The following day, I lost all vision and motor control. I took Delsym 3 days ago and am still experiencing side effects."

For Cough "I was traveling and started having a dry, allergy-related cough. Trying to suppress it long enough to give a presentation, and Delsym worked perfectly. But as others noted, I started to have diarrhea. I didn't connect it right away to Delsym, because when traveling everything is disrupted. Now home, everything had mostly cleared up, and I took the last dose last night, and sure enough, diarrhea is back today. I take no other meds."

For Cough "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."

For Cough "Well, it stopped my cough, but it also gave me extremely watery diarrhea that had me running to the bathroom every 10-30 minutes for hours and hours. It must have been at least 8 hours before my stomach calmed down. It left me feeling dehydrated and sick, but hey, at least my cough was gone, right?"

For Cough "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!"

For Cough "I read all these reviews and decided to try it, thinking it might work, but I was wrong. Do. Not. Take it. First of all, it barely helped my cough at all, some tea and honey could've done better than this. In fact, I think my cough got even worse. That part that was most upsetting was when I woke up feeling nauseous. I ignored it, and the next day took it again, and I got EXTREMELY lightheaded, just crazy dizzy. And then I got the diarrhea afterward... I just felt confused and out of it. This medicine is absolute trash, and I don't recommend taking it at all. I usually don't even write reviews either, so that should tell you something."

For Cough "First off, it tasted awful. Secondly, I thought I was dying on my bathroom floor an hour after taking it. It gave me chills, extreme nausea, diarrhea, and dizziness. Double-checked the expiration date to see if that had something to do with it, nope. My cough is calm, but it's not worth fighting nausea and dizziness four hours later. I will never take this medicine again."

For Cough "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 than 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 8 am. 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 I'm utterly exhausted. I'm not sure how it's even legal to sell this OTC."

For Cough "DO NOT TRY IT. I know some of you have had good experiences, and some have had bad ones. There have been more bad ones than there are good, I know that much. I took this medicine for my dry cough that I was having. I felt fine for a little while, went to sleep. And then about an hour after going to sleep, I woke up in a full-blown panic attack. I felt like I was going to black out, I kept having hot flashes and severe stomach pain. The feeling of throwing up was pretty bad too, but it never happened. I was shaking and almost went to the hospital."

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."

For Cough "I had purchased Delsym nighttime strength for a cold. The first night it worked great, the second night I got the worst pain in my upper abs, then 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."

For Cough "This stuff is useless, in fact, I am coughing more and worse after taking it. Thank goodness I only bought a small bottle, since it is kind of expensive for something that does not work at all. Will never take this garbage again."

For Cough "Took this tonight as I've been sick for three 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."

For Cough "It definitely helps my cough. But it makes me so dizzy, I feel like my surroundings are going by at 100 mph 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."

For Cough "My 8 yr old was having a dry, hacking cough after the flu. Used Robitussin, it helped a little. Bought Delsym children's and gave her 5 ml. She was complaining of a headache and stomach ache within an hr! She couldn't eat dinner, says she feels like throwing up. I'm rubbing her belly now and reading reviews now. Don't use this medication!"

For Cough "I was already drowsy from cold medicine and decided to take a dose of Delsym before bed to help me and my husband sleep better. I immediately felt anxious, wide awake, and restless. Three hours later, bad diarrhea. The effect it had on reducing my cough was minimal."

For Cough "Horrendous. Delsym did not stop my cough. I woke up at 4 AM (I had taken it 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!!!"

For Cough "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 it again for that reason. The diarrhea passed in about 12 hours."

For Cough "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 seem 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."

For Cough "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 Delsym 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."
