## 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.
