Drug Overview

LEADER™ Mucus Relief DM is a medication designed to help you manage cough and mucus associated with common colds or inhaled irritants. Each extended-release tablet contains 600 mg of Guaifenesin, which works as an expectorant to thin and loosen mucus, making it easier to clear from your airways. It also includes 30 mg of Dextromethorphan Hydrobromide, a cough suppressant that reduces the urge to cough, helping you find relief and get better rest.

This product provides 12-hour relief, allowing you to control your cough and improve the productivity of your coughs by clearing bothersome mucus from your bronchial passageways. With its dual action, LEADER™ Mucus Relief DM aims to make your experience with cold symptoms more manageable.

Uses

This medication is designed to help you breathe easier by loosening phlegm (mucus) and thinning bronchial secretions. By doing so, it 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 can reduce the intensity of your cough and help lessen the urge to cough, making it easier for you to get a good night's sleep.

Dosage and Administration
