## Questions & Answers

**Q: I have a post nasal drip that is making me nauseaous , which mucinex do you recommend ?**
A: Just regular Mucinex (not DM) is what my doctor recommended, and I've been taking, twice per day, for years.  The "DM" stands for dextromethorphan, which is a cough suppressant, and that's not generally needed when you're only trying to dry up post nasal drip.  Start with the 600mg, and if it doesn't do the trick, move up to the 1200mg tablets.  It works!

**Q: Do these come embedded on cards or in a small jar?**
A: In the cards. I always put them in a jar myself

**Q: Are you really selling ONE bottle of 500 pills for $162?**
A: If you 5 times the 100 ct package cost that I have been getting, the 500 pills at $162.00 seems reasonable.

**Q: Is taking two 600 mg tablets equivalent to taking one 1200 mg?**
A: Thank you for your questions! Two Mucinex® Extended-Release Bi-Layer Tablets (600mg per tablet) will provide the same dose as one Maximum Strength Mucinex® Extended-Release Bi-Layer Tablet (1200 mg per tablet).
