How to use
Take it exactly as your doctor prescribed or as the label directs. Shake the bottle well and measure each dose with the measuring cup or spoon provided, not a kitchen spoon.
How it works
Diphenhydramine blocks histamine and also acts on the brain to reduce the cough reflex. Ammonium chloride and sodium citrate help thin and loosen mucus. Menthol gives a cooling, soothing feeling in the throat.
