Delsym and Vomiting: What Users Say

For Cough "The first time I took Delsym (a couple of years ago), I landed in the ER because I thought I was dying: severe nausea, chills, sweats, shakes, dizziness, shortness of breath, and the dreaded diarrhea. I didn't make the connection that it was the Delsym until it happened to me again a couple of days ago. Almost identical symptoms as the first time, but this time instead of just nausea, I was also vomiting profusely. I'm glad it works for others, but please don't 'poo-poo' (pun intended) those whose experience was less-than-pleasant. We're all different, and what works for one won't work for another."

For Cough "Took only 2 doses for a cough and have been feeling nauseous and weak for going on 3 days now. Vomited on the second day. Horrible drug that, from all the other reviews I'm seeing, should not be sold! I have never had any reaction to any cold medicine anywhere close to anything like this before. Avoid!"

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 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 "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 "I am so confused about the explosive diarrhea reviews. Long story short, I got something last week that was more than just a common cold. Started with the usual scratchy throat, but by day 3, the cough was so unbearable that I later found out at urgent care I cracked a rib from coughing so hard. They gave me RX cough syrup, which I only took once since the codeine in it made me throw up violently (not fun with a cracked rib). Picked up some Delsym around 1 am at the pharmacy and actually slept for about 6 hours. Had to go to work the next morning and took my Delsym with me. Didn't need to take another dose until about noon. I truly feel like this medicine saved my other ribs from my own abuse! Try it once before assuming you'll poop your pants."

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."

For Cough "I have used the kid version with success for my children. It does work well to stop a dry cough. It lasts 8 hours, rather than 12. Unfortunately, the last time I used it for my child, she ended up dry heaving for hours and had a bout of explosive diarrhea. It stopped once the medicine wore off (about 8 hours after her dose)."

For Cough "I went to the pharmacy and asked the pharmacist for a medicine to calm my cough, and he recommended Delsym. I have been taking it for 3 days, and the cough has worsened because now every time I cough, I vomit. In these 3 days, I have not been able to keep a single meal in my stomach; just today I stopped taking it, and I stopped vomiting. Apparently, what was causing me the most damage was this medication. I do not recommend it at all."

For Cough "Made me have the worst panic attack of my life. Then I got bad stomach pain and nonstop vomited all night long, and diarrhea. I'm still nauseous the next day. I would rather be coughing. I'll never take this again."

For Cough "This medicine shouldn't even get a 1. Hopefully, you were smart and read the reviews before taking because I didn't. The first night I took it, I woke up in the morning and vomited three times. I continued to take it the following day (thought the vomiting was due to something I ate) and continued to vomit. I will never take it again."

For Cough "After I felt the early symptoms of a sore throat and cough, I picked up some Delsym Cold and Cough Nighttime since I had used the Delsym orange cough relief medicine before with some success. This formula was definitely a mistake. I took the first dose yesterday afternoon, and by yesterday evening I had loose stools and vomiting, but my first thought was maybe a virus on top of the cold... took the second dose in the early morning of today after coughing uncontrollably all night. Again, I was vomiting and still coughing. After the third dose and the same result this afternoon, I decided to do a little research and found these reviews. So glad I did. Never again!!"

For Cough "I took the Delsym, and exactly 10 minutes after taking it, every time it causes me to cough until I sometimes almost vomit. Makes it worse. :/"

For Cough "I’ve given this to my daughter twice, children’s dose, and both times she has vomited within 30 minutes. Do not recommend."

For Cough "Got rid of my cough fairly quickly, gave me an extremely upset stomach to the point of vomiting, and gave me diarrhea. Also experienced dizziness."
