Drug Overview

Rugby® is a medication designed to provide relief from mucus and coughing. It contains two active ingredients: guaifenesin (an expectorant that helps loosen phlegm and thin bronchial secretions) and dextromethorphan hydrobromide (a cough suppressant). Together, these ingredients work to make coughs more productive by clearing mucus from the bronchial passageways and temporarily relieving cough caused by minor throat and bronchial irritation, such as that from the common cold or inhaled irritants.

This medication is formulated as an extended-release tablet, allowing for 12-hour relief with just one dose. By reducing the intensity of coughing and decreasing the impulse to cough, Rugby® can help you feel more comfortable and even assist you in getting a better night's sleep.

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 also use this medication to temporarily relieve coughing caused by minor throat and bronchial irritation, which can happen with the common cold or from inhaling irritants. It helps reduce the intensity of your cough and can even lessen the urge to cough, making it easier for you to get a good night's sleep.

Dosage and Administration

When taking this medication, it's important to swallow the tablet whole—do not crush, chew, or break it. Make sure to take it with a full glass of water, which helps the tablet dissolve properly. You can take this medication at any time, regardless of your meal schedule.

For adults and children aged 12 years and older, the recommended dosage is 1 or 2 tablets every 12 hours, but you should not exceed 4 tablets in a 24-hour period.
