"Took Mucinex at 5 in the afternoon. Around 8, took my night meds. Next morning, stumbling around, body felt like it was flooded with heat-chest and arm pains. Had myself checked out and was ok. Pulled up the website to get a complete list of medicines not to take it with and found my answer there. If you have access to the internet, I would put the OTC medicine in and get a complete list of what not to take it with."

"Medicine works very well for the specified 12 hours, but wow, it is very strong. I weigh 105 pounds, and taking an entire pill will have me falling over and seeing double, very shaky also, but giving it a seven because at least I can breathe now, and this is the only medication that works for that, my inhaler won't even help me anymore."

"I'm nursing a 7-month-old baby. Had a bad sore throat, congested nose. Took Mucinex DM, only 4 doses, and it worked well. No side effects on the baby. I like it and recommend it. The 1st dose made my eyes watery, but then everything went okay."

"Took Mucinex DM for the onset of cough. The Mucinex the first day I noticed an improvement but had slight trouble sleeping. The second day no improvement from the Mucinex and zero sleep. In combination with my other asthma meds, it made my heart race, which made me have to take a rescue inhaler. I recommend going to the doctor before taking this with asthma patients."

"I had flu symptoms after a flu shot. They came on immediately, but the pharmacist at Walgreens said that the connection was impossible and recommended Mucinex. It does absolutely nothing to relieve the cough, runny nose, or anything. She said that the NyQuil I intended to buy wouldn't work. No more Walgreens or Mucinex for me."

"I took two pills of Mucinex DM for Covid symptoms, and it didn’t touch my cough or congestion. But, my eyes swelled shut and started leaking copious amounts of green goo, and my pulse was over 100 even at rest. Not a good first experience!"

"Had chest congestion, stuffy nose, and sore throat. The instructions recommended 1 or 2 tablets, it worked very well. However, I'm spitting aqua blue/green saliva??? Can't find any reference in my research indicating this being one of the side effects ..."

"My Dr. prescribed a Z-pack for my head cold. This usually kicks it by day 2. The night before taking my last dose, it returned with a vengeance. My Dr. suggested Mucinex DM. First dose stopped the coughing, by day 2, no more pressure or runny nose. Thanks, Mucinex, for curing my ick!!!"

"I have a cold with a cough, some post-nasal drip, and congestion. I took this before bed, hoping to calm the cough and get some of the stuck mucus out of my chest. It did help me suppress the cough, but also made me wake up at 4 am with a panic attack. Fingers tingling, face numb, heart beating crazy fast, and feeling nauseous and dizzy. Unable to fall back asleep. I have had a similar reaction with dextromethorphan before, but not since I was a kid. I don't recommend taking this if you have adverse reactions to sleep medicines or other sedating medications. I often have the opposite effect with those meds, and this was no different."

"The directions say to take 1 or 2 pills every 12 hours. I took 2 pills and landed in the ER. Very strong meds!"

"All this pill does for me is make me really lightheaded and numb all day. I’m never taking Mucinex DM ever again."

"This medicine definitely reduced congestion in my nose. I had not been able to breathe out of the right nostril for several days."

"Mucinex DM did not work for my son and me. Instead of controlling our cough, we coughed for hours. It did not loosen our mucus as stated on the box. I would not recommend this product."

"Fantastic! I panic if I don’t have these in the house. I get a terrible cough 2-3 times a year, and this suppresses cough so I can sleep and thins mucus at the same time."
