"This definitely works to clear up nasal congestion, but I took it at 5:30pm and was up all night. I haven't been able to sleep at all. It's now 4:30am & I'm still wide awake. I have to go to work so will be taking another dose in an hour to keep me up. I will not take a 2nd dose later today so I can sleep but I look forward to being able to breath while I'm at work so still worth taking the medicine."

"I have experienced fluid in my ears for almost two years. Consulted with two ear and nose specialists and with an allergist. Tried three types of nose sprays and other natural options, like additional vitamin C , pollen defense and the neti pot. Nothing worked until just recently I developed a severe cold and took Mucinex D. To my amazement and happiness the fluid drained from my ears. Clear ears! Problem - one cannot take Mucinex on a permanent basis."

"This worked on my sinuses, however my heart rate increases so much that I feel jittery. The insomnia is a set back. The relief is great but I'm not sure the things that go with it are worth it. Although my heart rate being up made me lose weight."

"Took DM at bed time and will never do that again! Yes I felt better and felt some relief,however, the heart palpitations were out of this world! I was so jittery still 3 hours later, that I literally couldn't sit still in my bed. Finally was able to sleep at 3 and woke up feeling super dehydrated and almost hungover, with puffy eyes and a bad headache. No Mas!"

"Works great on my sinus pressure/cold, now I can breathe no more stuff up nose or runny nose. Had no problem sleeping but it did give me a severe headache--so now trying half the recommended dose, got immediate relief just waiting to see if it will still give me a headache."

"I experience sinus problems frequently, mostly from allergies probably. I have headaches and stuffy nose etc. This medication is wonderful. I should receive money for how many times I have recommended this to people. I feel like I can even think clearer when I take this. I rarely experience side effects. Maybe one time I had dizziness. Great product."

"I’ve been taking Mucinex D for years. 2 a day—1 in the am and 1 in the pm. It was always affective for those stubborn wet coughs, helping me produce phlegm. Until fast forward, in my 30’s, post 2 kids and sleep doesn’t come so naturally anymore. I had no idea insomnia was a side effect until about 4 doses in this time. I slept 11-12am, then woke up at 2:30am and was WIDE awake and frustrated until 6am, in which I slept from 6-8am. Still not realizing it was from the Mucinex D I took more at 8am. By 7pm while trying to close my eyes and rest, my eyeballs popped back open, when suddenly I realized, “what if...” Sure enough, it was the Mucinex D causing me to be ridiculously tired but unable to sleep. It is the pseudoephedrine ingredient, which is a stimulant. Unfortunately, this side effect does not outweigh the benefits for me. So I’ll be drinking as much water as possible for the next 3 hours before bedtime and hoping for the best tonight. Maybe I should try the Mucinex plain and see how that goes."

"I had been struggling for several days with a severe head cold that was beginning to expand to my chest. I was using other over the counter medications with little effect. A co-worker mentioned Mucinex D and I began to experience significant relief with the first dose. I did add an over-the-counter nighttime pain reliever which really helped me to sleep through the night."

"Took this for relief as I looked and sounded pretty bad. I was keeping everyone up with my coughing and sneezing. I don't take medicine but I caved in and grabbed this. I guess from hours of exhaustion I passed out but woke up 2 hours later just wide awake! I couldn't go back to sleep, which made me so incredibly mad. I'm already an anxious person who is paranoid about everything. So this didn't help. It helped my cough calm down but the next day it was worse. I was able to sleep without feeling like my nose was plugged up!"

"My sister recommended this to me while I was experiencing several nasal congestion and cough. The product works GREAT WHEN USED AS DIRECTED. She suggested taking 2 (12 hour) pills instead of the one that was suggested on box. (She had done this and thought I'd be okay) I experienced VERY SEVERE side effects. I became extremely light headed, dizzy beyond belief, lose of concentration, and severe loss of apetite. I literally felt like I was walking on clouds. I suggest also not taking this at night as it will keep you up ALL night. One pill in the morning is enough to get you by."

"This is my second day of using Mucinex. At this point I'm not sure why my doctor recommended it. I never did have congestion, just a sore throat. Anyway, I'll not take it anymore, it's 1:00 a.m., I'm totally exhausted and cannot sleep. Last night it was 12:30 or so, and I finally went to sleep. I'm use to falling asleep around 9:30. I do take sleeping pills and I just took my dose of those, hope it puts me to sleep, otherwise, how do you make it through the next day? I just read the label, guess I missed before that it can cause sleeplessness, or I would't have taken it at all. It's expensive and another drug going in the garbage can!"

"I had an experience with a rare side effect. I began sweating profusely after taking the pill (recommended dosage) after 3 days. After reading further, I have figured out that I drank 2 cups of coffee the third morning when I took the pills, which led to the sweating. Otherwise, I have had no adverse side effects, and it works great! It is just not a good combination with coffee!"

"Started it yesterday. I think it helps but I just realized it is the reason I'm warm. Feels just like a low-grade fever. I also take something for ADD, which is a stimulant. I think the combination of the two is what is causing the rise in body temp."

"Terrible product! Won't buy it ever again. I took it at 9 p.m. Unfortunately without checking the side effects. My cough is somehow got better but it's 2 a.m. and I'm still anxiously awake! I have a toddler, I can't afford to stay awake when he is finally asleep. Don't buy it! Not worth it!"

"Took this about three days into a pretty bad cold to relieve congestion especially in my sinuses...worked a charm! Took the adult dose around noon that day. didn't have the same jittery side effects some are reporting and was, thankfully, able to take a nap that afternoon with the sinus relief it provided. my mom on the other hand says she can't take it after noon or else she won't sleep all night, so I understand your pain! All in all, worked great for me but understand that some people (for whatever reason) might have trouble sleeping if taken too late in the day"

"All I do is simply plan taking this in relation to my sleep routine. I take it in the morning and then that way it has no effect on my sleep and it gives me the entire day to expel whatever needs to come out."

"I was starting to feel like a head and sinus condition coming on and with our tropical vacay coming up in 10 days, I for sure wanted to kick it in the butt. Well, I took my first dose this evening at 9 pm, went to bed because of an early work schedule and slept soundly till 11:30 pm. It is now 2:30 am and I have experienced rapid heart beat, nausea and jittery. I laid there for 2 hrs thinking I could go back to sleep, and here I am. Kinda wished the pharmacist would have given me a heads up. Now this is kickin me in the butt!"

"After coughing for several weeks I went to my doctor who prescribed an antibiotic and Mucinex DM. I took the first tablet and drank a lot of water. Immediately my coughing was very productive. I highly recommend Mucinex DM!"

"So I woke up coughing really bad lastnight and I had some mucinex dm night time. I took that to help me loosen up whatever was in my system. About 5-10 mind later I had this terrible terrible urge to throw up. This stuff does not settle in my stomach at all. This is the 3rd time I've tried it within a 2 month span. Everytime I feel worse. I'm just going to get rid of it. Not for everyone..."

"I took one Mucinex DM at 11 am and coughing and mucous flow was reduced significantly, although accompanied by dry mouth. Yesterday at noon I would have given it 10/10. However, I took one capsule at 8 pm and had severe insomnia and could not fall asleep until 8 the next morning. "

"I went to Urgent Care Center today for a sinus infection. I got a prescription and was told to take mucinex D. I took it a couple of hours ago and I've been feeling weird ever since. It's ineffective so far and I feel kind of dizzy. I want it out of my system NOW."

"I am a long-time sinus sufferer. Mucinex is a God send. Mucinex-D works fabulous for the morning and all-day relief. For bed, I just take Mucinex (without the D) so that I don't have the stimulant effect of the pseudoephedrine running through me. Works like a charm to get some sleep. Do not like generic versions. They don't work like the brand-name Mucinex does. Expensive but so worth every cent!"

"Well, since I’m writing this at 4:36 am, then you will know why. I took the first pill at 4pm when I bought it. I haven’t noticed much difference in my cough or mucous but I CAN NOT SLEEP. I'm not even close to tired. My kids will be waking up in a few hours. How in the world will I function through tomorrow? Never ever again. I do not recommend the pseodoephdrine keeps you awake. Your body does it’s best healing while you’re sleeping. Well...."

"Please, if you`re going to try and treat a cold then go the natural route ! I learned the hard way. I`ve been sick with sore throat and nasal congestion since Tuesday-Wednesday and finally I asked my mom to go out and get medicine. My Mom went out and brought me Children`s Mucinex and after taking 2 doses [I`m 18 years old and 2 doses of the children's medicine is equivalent to the original] I lost all senses of smell and it wasn't worth it at all. I regret taking Mucinex and I googled this symptom and the people who has had this problem still has yet to gain there sense of smell back. I'm so afraid. On top of that I feel no real relief, just more pressure on my breathing."
