Dextromethorphan / guaifenesin "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."

Dextromethorphan / guaifenesin "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."

Dextromethorphan / guaifenesin "The expectorant “guaifenesin” is superb, and I usually take Mucinex for severe COPD issues on a regular basis. However, Mucinex-DM is not covered by my insurance, Mucinex is. With a severe cough, I was RX generic Robitussin DM. Worked very well. NOTE! I take several OTC meds regularly, and all but moisture eye drops (for me, and not RX covered) my Dr. writes a script for, and are MUCH less $$ than buying the same meds OTC. Insurance coverage, including Medicaid (not sure about Medicare, check it out anyway), may save major $$ by getting an RX for OTC meds. Never hurts to ask for an RX, and it’s easier than asking your insurance company, which U can do, as long as U don’t die on hold..."

Dextromethorphan / guaifenesin "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."

Dextromethorphan / guaifenesin "I am on my fourth day sick with what is likely bronchitis. It has gotten worse every day so far. Robitussin DM has worked the best for me. I have spent a good amount of time researching the best OTC medications for cough suppression and chest congestion. So far, Robitussin DM is the only one that provides any relief."

Dextromethorphan / guaifenesin "So I woke up with a dry cough that hurt my chest really bad. Felt like phlegm was stuck in my chest and had trouble falling asleep due to the cough. Took two doses today alone and feel a bit relieved. My cough is more phlegmy and the chest pain isn’t as bad anymore due to my not coughing as harsh with the medicine. BUT I will say EAT haha because yeah I did not and had a bad stomach ache/diarrhea. Looked it up and you are supposed to eat with it, so don’t make the same mistake I made!"

Dextromethorphan / guaifenesin "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."

Dextromethorphan / guaifenesin "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."

Dextromethorphan / guaifenesin "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!"

"This medication is only slightly less effective than codeine or hydrocodone in treating cough and has fewer side effects than both. The only negatives are the frequent required dosing and the unpleasant taste from these products."

Dextromethorphan / guaifenesin "Safetussin is a pretty safe drug. I have been suffering from a nagging cough associated with sinusitis, and it has been able to manage it. This drug is especially useful for people who respond badly to Delsym due to the fact that it has 1/6 the level of cough suppressant (DXM). Overall, a great choice for people who don't want to take Delsym."

Dextromethorphan / guaifenesin "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!!!"

Dextromethorphan / guaifenesin "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."
