Drug Overview

This medication combines three active ingredients: dextromethorphan HBr, guaifenesin, and phenylephrine HCl. Dextromethorphan HBr acts as a cough suppressant, helping to temporarily relieve the urge to cough, which can be particularly useful for getting a good night's sleep. Guaifenesin is an expectorant that helps loosen phlegm (mucus) and thins bronchial secretions, making coughs more productive by clearing mucus from the airways. Phenylephrine HCl serves as a nasal decongestant, providing temporary relief from nasal congestion often associated with colds.

This combination is designed to offer multi-symptom relief, addressing nasal and chest congestion while controlling cough and thinning mucus. It is suitable for individuals aged 12 and older and is available over-the-counter.

Uses

This medication is designed to help you breathe easier by loosening phlegm (mucus) and thinning bronchial secretions. This action helps clear out bothersome mucus from your airways, making your coughs more productive.

You can use this medication to temporarily relieve cough caused by minor throat and bronchial irritation, which can happen with the common cold or from inhaling irritants. It also helps reduce the intensity of your cough and the urge to cough, making it easier for you to get to sleep. Additionally, it can help relieve nasal congestion associated with a cold.
