What is this drug?
This is a cough syrup that combines three active ingredients — diphenhydramine (an antihistamine that stops coughing and dries up a runny nose), sodium citrate (which helps loosen thick mucus so you can cough it out easily), and menthol (which gives a cooling feeling and soothes your throat). It is commonly sold in Nigeria as Tussylin Cough Syrup Adult.
