Reviews for Dextromethorphan/guaifenesin

CJ · Taken for less than 1 month December 2, 2020

Mucinex DM (dextromethorphan / guaifenesin) for Expectoration: “215 lb. male with headcold / chestcold and extreme congestion. Only used Mucinex for two days during daytime with lots of H2O. Broke all congestion loose resulting in sinus drainage and productive cough. Great stuff. Made me feel kind of "buzzy". I would not recommend mixing with other meds (e.g., Nyquil). This would likely cause adverse reactions. Very important to over hydrate when taking!”

For Cough: “I have taken dextromethorphan/guaifenesin for over 10 years. I have no side effects that I am aware of. My doctor knows I take. It helps my congestion and cough.”

For Expectoration: “Took medicine and it actually helped me feel good for once since I’ve been sick with a chest cold for two weeks . So sick I couldn’t even go drinking . As far as the side affects , don’t worry people it’s not crack in a bottle it’s only cold medicine.”

Mucinex DM (dextromethorphan / guaifenesin) for Cough: “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) for Cough: “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.”

Mucinex DM (dextromethorphan / guaifenesin) for Expectoration: “I wasn't feeling well and it was recommended that I try Musinex DM. I took one 12hr pill and started to feel better or so I thought. Half through the 12hr dose I started to have blurry vision and I could feel something covering my eye. I went to look at my eye and I had green mucus coming out of it. First it was one eye, then it was both. I thought I might have conjunctivitis (pink eye) but once I stopped taking the Musinex DM the issue went away. I will never again take this product. Just doesn't work for everyone.”

Mucinex DM (dextromethorphan / guaifenesin) for Cough: “Am nursing to 7 months old baby. Had bad sore throat, congested nose. Took Mucinex DM only 4 doses & it worked well. No side effects on baby. I like it & recommend it. 1st dose made my eyes watery but then everything went okay.”

Mucinex DM (dextromethorphan / guaifenesin) for Expectoration: “While taking Mucinex DM 600mg, twice a day for 7 days, I hadn't realized why I was itching something fierce. Until my 7th day when I looked up the side effects. Absolutely nothing helped to ease the itch all over but scratching. Other than that, my congestion has eased significantly.”

Mucinex DM (dextromethorphan / guaifenesin) for Cough: “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) for Cough: “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.”

Robitussin Cough + Chest Congestion DM (dextromethorphan / guaifenesin) for Cough: “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...”

For Expectoration: “Took an off brand mucinex around 10:00 pm, (same ingredients). I fell to sleep and woke up at 2:00am with extreme anxiety, dizziness, rapid heart rate, diarrhea, nausea, dry mouth, and shakiness. Will never take this medication or anything like it again. I'm glad I only took one tablet.”

For Cough: “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.”

Mucinex DM (dextromethorphan / guaifenesin) for Cough: “The directions say take 1 or 2 pills every 12 hours. I took 2 pills and landed in the ER. Very strong meds!”

Duratuss DM (dextromethorphan / guaifenesin) for Cough: “This medication has a lot of side effects and it is gross. It did not help with my symptoms at all partly because I could not get over the taste, and it produces really bad headaches.”
