Drug Overview

Rugby® is a maximum strength medication designed to provide relief from mucus and cough. 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 your coughs more productive by clearing mucus from your airways and reducing the urge to cough, which can help you rest better, especially at night.

This medication is formulated as an extended-release tablet, allowing for 12 hours of relief from cough and mucus associated with common colds or inhaled irritants. By easing throat and bronchial irritation, Rugby® can help you feel more comfortable and improve your overall breathing.

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 with absorption. 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 one tablet every 12 hours. However, you should not take more than two tablets in a 24-hour period. If you have children under 12 years of age, this medication is not suitable for them, so please avoid using it for that age group.

What to Avoid

You should avoid using this medication if you are a child under 12 years old. Additionally, do not take it if you are currently using a prescription monoamine oxidase inhibitor (MAOI), which is a type of medication often prescribed for depression, psychiatric conditions, or Parkinson’s disease.
