The flagship cough syrup and cold care brand is marketed in several countries as Benylin DM, for its active ingredient, dextromethorphan. However, the range of products available in both solid dosage and liquid forms have formulations with multiple ingredients including pseudoephedrine, paracetamol (acetaminophen) and guaifenesin.
In 2016 it was one of the biggest-selling branded over-the-counter medications sold in the United Kingdom, with sales of £36.8 million. The brand was sold by Pfizer to Johnson and Johnson in 2008.
