User Reviews for Mucinex DM oral

Don’t take this at night cause the cough will keep you up all night after you take this sometime in the afternoon.

I was in the hospital for a couple of days with asthma exacerbation(ithink thats how you say it) my meds at home were not working and I couldnt get rid of this insane and persistent thick mucus in my lungs and nose that kept making me wheeze like crazy. As soon as I started the medicine I started feeling relief. Day 3 im clear and can finally breathe on my own and all mucus is gone. Day 5 on it (per instructions from doctor) i start having terrible cramps, nausea, and watery diarrhea. In conclusion: medicine is very effective but the side effects can be very uncomfortable. But once you stop taking it the side effects go away quickly and youre left with no mucus. Recommend only for those who are more desperate for relief and need something stronger.Read More Read Less

I had nasal congestion, a lot of drainage that led to sore throat, and had begun to cough. My brother recommended that I take some Mucinex. I actually had some DM from a year or two ago and it was still good (exp 6/24). This stuff worked as advertised! Been taking it for 3 days now. Today, Day 4, I've begun experiencing dizziness all day. I'll take the next dose before I go to bed and stop there. My cold should be cleared up. If not, I'm seeing my doctor tomorrow anyway, so he can help me from there. Haven't had any gastric issues like others have reported, but the dizziness is a big concern. Read More Read Less

Took this at the tail end of an illness, just to kick the end of a cold that had been hanging on. Took before bed, and, felt a little dizzy as I was getting into bed, and slept horribly. Took again in the morning, and went to work. About an hour later, got really dizzy, blurred vision, tight chest. Ended up in the ER, with blood pressure 205/140 (I'm normally 115/80). The ER dr thought I had OD'd on amphetamine. Arms and legs constantly flailing. Lots of valium calmed things down, but, two days later, mind was still foggy and couldn't count past 7. Too ~ 5 days before I was able to function again.Read More Read Less

Dear Sick Humans, Picture this. It’s Christmas Day 2022. You’ve arrived at your Mother’s house for your family’s annual Christmas Day feast. As you noticed a tickle in your throat and a slight cough, you grabbed some Mucinex DM from the convenience store on your way up. Don’t need anyone eye’in you like you got the “VID”. You throw the two Mucinex DM tablets back with some water (likely not enough) without any thought to the fact that the last time you ate was yesterday. Similarly to Thanksgiving, your family opts to forego ALL meals for the day in anticipation of said feast. Fast-forward 30 minutes. The Bird is out of the over resting. The mac and cheese is coming out of the oven. The rolls are being buttered. Everyone is starting to sit around the table as they prepare to Bless the food. And then it happens. A VERY audible DROP. A gurgling sound is produced for your lower gut. This is NOT a “hunger” gurgle. This is a “you have 3.7 seconds to make it to the nearest restroom cuz it’s about to get UGLY” gurgle. You hurriedly excuse yourself from the table and B line it. You clench tighter because the closer you get to the bathroom, the more violently your stomach churns. At the very last moment you arrive… and it’s occupied. I’ll spare you guys the details.. as I’m sure you can imagine how this ended. The moral of this story is that this medicine may cause physical and emotional damage… and you may end up having to replace the carpet at your mom’s. AVOID AT ALL COSTS. Read More Read Less

This stuff was very effective for reducing nasal congestion, post nasal drip and it got the mucus out. Cons... As soon as I took it, I felt an immediate rumble in my stomach and was up all night with watery diarrhea. My heart felt like it was gonna jump out of my chest. Couldn't sleep, tried to combat that with melatonin, 40mg and still couldn't sleep. When morning came around, I got up feeling drunk and loopy with a headache and was just mad at everything around me. Would completely recommend this product for someone you don't like.

This stuff helped relieve congestion but made me violently vomit. Burning, rotting sensation in my chest, n diarhea. Thought I also had the flu but realized each time I took this med, I felt so sick. Horrible! Id rather have my cough than deal w this rotting feeling from Mucinex Max.

I had been coughing and wheezing for 3 weeks. My Dr. recommended Mucinex. On day 4 I had some stomach pains. By day 5 it was explosive diarrhea. It did clear up my wheezing but wow, what a side effect!

Used for 3 days HAD TO THROW AWAY!!! Caused very watery diarrhea and made me dizzy!!!!!! Felt very hungover on this medication. Read and repeat. STAY AWAY!!!

I was a bit congested and had a cough so decided to buy Mucinex. I took my very first dose this afternoon and noticed later had diarrhea for some reason, couldn't figure out why until I googled it and sure enough this does case diarrhea. I only took one dose (two tablets) and never used Mucinex before in my life, I'm taking this right back to Walmart for a refund, spent $ 13.00 on this and definetly not using again after this happened. What really concerns me is the really more severe reactions some people encountered. Read More Read Less

My husband and I took this before bedtime to help with our cold. We both slept horribly and woke up feeling hungover. It took most of a whole day to recover from it.

Took this right before dinner after being super congested with post nasal drip the last 2-3 days. It’s now been 6 hours since i’ve taken it and my cough has gone down, congestion a little better but i can’t tell if that’s from the meds or me feeling better. Regardless, this medication is terrible. Not worth the dizziness and lightheadedness im feeling right now. Just take some benadryl and go to sleep or try some Xyzal instead

I'm took me some eggs for a cough and runny nose within 30 minutes of taking the first pill I was in the bathroom with the major diarrhea

My husband took this medication before bed this past weekend. At 3 AM he woke to use the restroom where he completely collapsed and ended up putting his head through a wall when he fell. He was not conscious and suffered a head injury as well as a shoulder injury requiring evaluation at the hospital. The conclusion was that this medication has the cause of this event. If he would have fallen 6 inches in the other direction, he would have died due to the blunt force trauma.

This medicine made me so sick to my stomach. Shortly after taking I was dizzy and had nausea. Went to bed and woke up with horrible diarrhea. Didn’t realize it was medicine and took another dose. I had the worst stomach cramps and diarrhea I have EVER had. Once medicine was out of my system my stomach stopped hurting. I would rather of had the mucus than dealing with side effects of this medication.

I took this medication and about 20 to 30 min. I cant breath and i throw up more than 10 times. My head was light and chills. Do not take this medication. Terrible!

I came here to see if I was the only one. NOPE! I took a single dose. Yesterday morning. The diarrhea started 30 minutes later. I have been reduced to peeing from my rectum, like a pigeon. No more normal BMs for me apparently…. Will not be taking another dose. Ever.

It’s really not bad at all taken alone for me. I had mild diarrhea and some tiredness but nothing crazy. It’s when I took it with Advil Cold & Sinus that the main issues happened. Mainly vomiting and severe diarrhea with intense cramps. Would not recommend taking with other cold and sinus medication

I am here bc of the diarrhea symptoms!!!! I have been on it for about 4-5 days for a bad cold. Worked great for working some gross stuff from my sinuses…. Also working some gross stuff from my gut ????

I took mucinex because of congestion. Immediately felt sick to my stomach and kept me up all night. This stuff needs to be banned
