Ammonium chloride; Sodium citrate; Squill; Menthol

Who is this for?

This is a combination cough mixture (commonly sold as Menthodex Cough Syrup) that works in several ways — ammonium chloride and squill help loosen thick phlegm so you can cough it out more easily, sodium citrate helps reduce the thickness of mucus, and menthol gives a cooling, soothing feeling in your throat and airways.

Is Ammonium safe to take with another drug?
