What is Guaifenesin

Guaifenesin is an oral expectorant, which is commonly used to treat cough due to colds and minor upper respiratory infections. Despite its long history of use since the 1950s, the efficacy of guaifenesin has only recently been substantiated.

Guaifenesin is used for dry, nonproductive cough when there is the presence of tenacious mucus and/or mucus plugs. The results of a few studies have favored active treatment with guaifenesin over placebo in treating productive cough due to upper respiratory illness (URI).

In patients with chronic bronchitis, guaifenesin, is not recommended for aiding with cough suppression since studies have shown no benefit in reducing cough.

However, the mucolytic properties of guaifenesin may be independently helpful in clearing mucus, and patients may subjectively report benefit to use.

Guaifenesin is an ingredient contained in many combination non-prescription (over-the-counter or OTC) and prescription cough and cold products.
