Dextromethorphan is a cough suppressant. It affects the signals in the brain that trigger cough reflex. Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth. Phenylephrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose). Dextromethorphan, guaifenesin, and phenylephrine is a combination medicine used to treat cough, stuffy nose, sinus congestion and chest congestion caused by allergies, the common cold, or the flu. There are many brands and forms of this medicine available. Not all brands are listed on this leaflet. This medicine will not treat a cough that is caused by smoking, asthma, or emphysema.
