Guaifenesin is a drug to treat cough with phlegm . This drug can relieve phlegm buildup in the respiratory tract due to colds, infections, or allergies. Guaifenesin can not be used to relieve coughs caused by chronic obstructive pulmonary disease (COPD) .

Guaifenesin works by thinning phlegm, so that phlegm can be more easily removed from the respiratory tract. Many medicinal products containing guaifenesin are sold freely and are often combined with other cold and cough medicines.
