Clinical
Dextromethorphan is used to temporarily relieve cough caused by the common cold, the flu, or other conditions. Dextromethorphan will relieve a cough but will not treat the cause of the cough or speed recovery. Dextromethorphan is in a class of medications called antitussives. It works by decreasing activity in the part of the brain that causes coughing.
Read the full MedlinePlus article ↗This is an over-the-counter liquid cough and congestion product taken by mouth. It contains three active ingredients commonly used together for cold and flu symptoms: dextromethorphan is a cough suppressant, guaifenesin is an expectorant that helps thin mucus, and phenylephrine is a nasal decongestant. This product is marketed as an OTC monograph drug, meaning it follows FDA's established rules for this category of combination cold and cough products.
