Dextromethorphan / guaifenesin for Cough "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."

For Expectoration "Took an off-brand Mucinex around 10:00 pm, (same ingredients). I fell asleep and woke up at 2:00 am 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."

Dextromethorphan / guaifenesin for Cough "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."

Dextromethorphan / guaifenesin "A guy on here said it made his heart race, which made him use his inhaler? Asthma inhalers can make you jittery, so you literally did the opposite of what you should have done. Another person said something about a flu shot and them telling him the flu symptoms were not related? Come on, the vaccine is a weakened version of the flu, so of course it causes flu symptoms. I wouldn't expect it to do much in that situation, but usually, when experiencing coughing at night, the suppressant is good, and with congested sinuses during the day, the expectorant is good. Check for possible interactions with other meds, hydrate PLENTY, don't just start by taking the highest recommended dosage. This is not a cure for COVID or other viruses, but it can help clear out phlegm. Definitely not for everyone but works for most."
