Drug Overview

Equate™ is an oral solution designed to help relieve cough and chest congestion. It contains two active ingredients: dextromethorphan HBr, which acts as a cough suppressant, and guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions. This combination temporarily alleviates cough caused by minor throat and bronchial irritation, often associated with colds, while also helping to clear mucus from the airways.

This product is suitable for individuals aged 12 and older and comes in a pleasant raspberry flavor. It is formulated to control cough, relieve chest congestion, and promote the drainage of bronchial tubes by thinning and loosening mucus.
