Review: product that does one thing and does it extremely well - Well, I can’t remember when I first started taking this but have been for many years. It is nothing short of a great product and is very effective at clearing congestion and is my only go to FOR doing so I know there are other products out there similar, but this is the benchmark of decongestants and will be the only one that I buy
Review: Works very well for lung congestion due to seasonal allergies - The active ingredient in this medication is Guaifenesin, which loosens phlegm and increases the lubrication of your lungs allowing so your cough is more productive and your bronchial passages stay clear. If you're like me and have lots of bronchial congestion and asthma type symptoms in the spring when there's lots of pollen in the air or if you're just suffering because of a cold, you want something that will work to relieve it without making you jittery like some medications and one that you don't have to worry about taking every 4 or 5 hours. I've had good luck with this one. I'd tried the regular strength Mucinex, the one in the green box, which contains the ingredients 600 mg Guaifenesin and 30 mg Dextromethorphan HBr when I had one of those coughs that seem to go on forever, one that kept me up at night, due to a cold. It worked well on the cough but wasn't strong enough to keep my lungs clear. I still had that tightness in my chest. This one contains only the Guaifenesin, but it has 1200 mg which is strong enough to do the job. I haven't had a cough since trying it, so I don't know if it would help with that. The instructions say to drink plenty of fluids because it draws liquid into the bronchi. The water both thins mucus and lubricates the airway, facilitating the removal of mucus by coughing. Some people have mentioned their nasal passages or throat feeling dry after taking this medication but I haven't noticed that. Maybe it's because I drink a lot of water. (And Diet Coke) I haven't noticed any side effects after taking it for a few days. The tablets are a little large, probably because they're time released, so if you have a problem swallowing pills, these could be a little difficult. I like that I only have to remember to take them every 12 hours. Actually, the effects seem to last a few hours past that.

## Questions & Answers

**Q: What is the difference between mucinex and mucinex dm?**
A: Per the internet, Mucinex Dm (Dextromethorphan / Guaifenesin) is okay for loosening congestion in your chest and throat, but it could prevent you from coughing the mucus up. It comes as an extended-release tablet and a short-acting liquid. Mucinex (Guaifenesin) reduces the thickness and amount of mucus in your throat and chest.

**Q: How long is the Exp. date on the Musinex 28 count?**
A: 1/2021 is the shortest expiration date that we have...

**Q: Unless this is 2 boxes of 28, your count per pill is wrong. It would be .89/count and not .45/count, so is it one box or two?**
A: I received two boxes (one each of 14 individually blistered packets) equaling 28 pills).

**Q: what is the expiration date on the package?**
A: All items sold by EJ Sears Enterprizes have a date of one year or better on an expiration.
