What is Duravent DM?
Dextromethorphan suppresses coughing by affecting the brain signals that trigger the cough reflex. Guaifenesin loosens up congestion in the chest and throat. Phenylephrine shrinks the blood vessels in the nasal passages. Duravent DM, a combination medication, is used to treat allergies, flu, common colds, or coughs caused by the flu. Duravent DM does not treat a cough caused by smoking or asthma. This medicine is available in many different brands and forms. This leaflet does not list all brands. Duravent DM can be used in other ways not mentioned in this guide.
