Mucinex DM (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 website to get 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."

Mucinex DM (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 shakey 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 any more."

Robitussin Cough + Chest Congestion DM (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 Robotussin 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$$ then buying the same meds OTC. Insurance coverage including Medicaid (not sure about Medicare, check it out anyway) may save major$$ by getting a RX for OTC meds. Never hurts to ask for a RX, and it’s easier then asking your insurance company, which U can do, as long as U don’t die on hold..."

Mucinex DM (dextromethorphan / guaifenesin) "Took mucinex md for the onset of cough. The musimex the first day I noticed an improvement but had slight troubled sleeping. The second day no improve the from the mucinex and zero sleep. In combination with my other asthma meds it made my heart race which made me have to take rescue inhaler. I recommend going to dr before taking this with asthma patients."

Mucinex DM (dextromethorphan / guaifenesin) "(51F) I took two pills of MucinexDM 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!"

Mucinex DM (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 Walgeens or Mucinex for me."

Mucinex DM (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 medication. I often have the opposite effect with those meds, and this was no different."

"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."

Safetussin DM (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 that respond badly to delsym due to the fact that it has 1/6 the level of cough suppressant (dxm). Overall, great choice for people who don't want to take delsym."
