For Cough "I’ve had apparently the flu that’s been evading tests for over two weeks now. I’ve been on Promethazine DM for half of that time, and not once has my cough let up. My abdominal muscles are so sore, and I feel like there’s a hole in my left lung. I’m young, 24. I don’t have preexisting lung issues, so I’m extremely distressed that this medication hasn’t helped despite such high praises. This medication didn’t even make me drowsy nor stop my vomiting as claimed it would. I literally took 5 ml of nasty syrup for nothing is how it feels."

For Cough "I may as well have taken 10 mL of water. This medication does absolutely nothing for my cough and doesn’t create enough drowsiness to help me sleep through the urge to cough. NyQuil has worked 100% more than this stuff. If I could get a refund from the pharmacy, I would!"

For Cough "I was prescribed Promethazine DM to help with my cough during the daytime, but I only used it at night. I was instructed to take 5 mL, instead, I doubled my dosage so I would be able to sleep throughout the entire night, and that worked perfectly. I wouldn’t recommend taking it during the day due to drowsiness being a significant side effect."

"I’ve been battling pneumonia for a long time, and when the infection cleared up, my lungs then had to get rid of all the debris and gunk. I was coughing so violently for days without sleep. My body was exhausted. I went to the ER for fluids and steroid IV and was given this to take home. Wow! This helped me sleep, stopped my cough, and made me feel like a new person. It does make you groggy the next morning, but it’s worth it. I’ll be asking for this medicine every time I’m sick from now on."

For Cough "My doctor had told me it would make me drowsy, but instead, I had a hard time going to sleep. I felt like my heart was racing all night. I was scared I was having a heart attack."
