I used to use these when I got sick, but I'd wake up shaky. Turns out it ws causing problems with my seratonin levels. Won't be taking anymore.

Mucinex DM is a combination medication designed for the comprehensive treatment of both wet and dry coughs. It combines two active ingredients that work simultaneously. Its unique design is its two-layer formula: one layer acts immediately after administration, while the second provides a gradual release of the ingredients, providing a lasting effect for up to 12 hours. This effective medication offers immediate benefits. Dosage is twice daily.

Sinusitis
Verified Purchase
I bought this for a family member who suffers from sinusitis. It's useful when symptoms are mild or as an emergency. It's convenient to be able to purchase it in Japan.
