Drug Overview

Mucus Relief DM is a medication designed to help you manage cough and chest congestion. It contains two active ingredients: Dextromethorphan HBr, which acts as a cough suppressant to reduce the urge to cough, and Guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions. This combination makes it easier for you to clear mucus from your airways, making your coughs more productive and providing temporary relief from coughs caused by minor throat and bronchial irritation, such as those associated with the common cold.

This maximum strength formulation is intended for individuals aged 12 and older and is available in a 6 FL OZ (180 mL) bottle. By alleviating the impulse to cough, Mucus Relief DM can also help you get a better night's sleep while effectively relieving chest congestion.

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 can help reduce the intensity of your cough and lessen the urge to cough, making it easier for you to get a good night's sleep.

Dosage and Administration

It's important to follow the correct dosage when taking this medication to ensure your safety and effectiveness. For adults and children aged 12 years and older, you should take 20 mL every 4 hours, but remember not to exceed 6 doses in a 24-hour period. If you are caring for children under 12 years of age, this medication is not recommended for them.

When measuring your dose, always use the dosing cup that comes with the medication. This ensures you get the right amount. Avoid using this dosing cup with any other products to prevent confusion and ensure accurate dosing. If you have any questions or need further guidance, don’t hesitate to consult your doctor.
