For Cough "Took a dose of Delsym at 10:30 pm. Awoke at 3 am with diarrhea and dizziness. At 7:30 am: headache, dizziness, nausea, and pupils were dilated. Now, 18 hours later, still dizzy, headache with dilated pupils."

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 "DO NOT take Delsym with alcohol. Nowhere on the box does it say that! I had wine with dinner and later took the prescribed dosage of Delsym because I had a cough that was preventing me from sleeping. The next thing I knew was waking up on the kitchen floor with ambulance personnel in my house! I hit my head on the floor, which caused a brain bleed. I had to be airlifted to a regional hospital and put in the ICU. Luckily, the bleed stopped and they didn't have to crack my head open to do brain surgery! Recovery was a nightmare with months of headache, dizziness, and zero energy. I still have residual effects a year later. They did a lot of tests in the hospital to figure out what caused me to faint, but all of them showed no problems, so it had to have been the Delsym. I don't know for sure, of course, that the combination of wine with Delsym caused me to pass out. It could have been just the Delsym, but I want to warn people. This stuff is dangerous!!!"

For Cough "I took this syrup after my dinner and woke up with a heavy head and dizziness, and it only got worse by the afternoon. To an extent that if I close my eyes, everything will start spinning. It's more than 24 hours now, and I am still facing this issue. Will never recommend this to anyone."

For Cough "I took this because my family flew into town and I couldn’t stop coughing. I got a terrible headache and got very dizzy and nauseous. After the nauseousness passed, I was straight tripping. I can’t believe this stuff is legal. Don’t take it unless you have absolutely no other choice whatsoever."

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."

For Cough "My mother and I both took 1 dosage of Delsym at night, and the next morning we both have been feeling dreadful. We both have been coughing for 2-3 weeks and felt like we were getting better until we took this medicine. I do NOT recommend this medicine for anyone! 12 hours after taking it, I'm feeling very sharp pains in my chest when I breathe and cough, also along with mild headaches."

For Cough "Have taken Delsym for 3 nights for cough due to a common head cold/drainage. It did stop the cough, but I still didn’t sleep well, and each morning I have woken up with a terrible headache/hangover feeling. For the first few days, I was also taking Mucinex, but I didn’t take it last night - only 10 ml of the Delsym. I have been drinking lots of water and eating good healthy food, but this morning I have one of the worst headaches of my life. Feel like if I move my head, I’ll throw up. Update - Almost exactly 12 hours after taking Delsym (12-hour extended release) last night, my debilitating headache has lifted and I’m nearly back to normal! I must be one of the people who is sensitive to this drug."

For Cough "Delsym Cough (orange flavored) has really worked on my cough. I did have a pretty good headache, but I took ibuprofen for that. I have not experienced any stomach problems other than nausea when I woke up this morning, and I threw up. I was able to go to work today."

For Cough "Took 8 ml yesterday and felt okay, stopped my dry hacking cough, but woke up with a mild headache, which I attributed to coughing so hard the day before. Took another 8 ml about 14 hours after the last, and within an hour it gave me diarrhea and stomach pains. I also feel lightheaded. Drinking lots of water as it is excreted through urine. It worked, but not worth the side effects - I usually take child doses due to my size and weight, should have done that with this! If you are going to try this, start with half a dose and drink lots of water!"
