Drug Overview

Tussin DM is a cough syrup designed for adults aged 12 and over, available in a pleasant cherry menthol flavor. It contains two active ingredients: dextromethorphan HBr, which acts as a cough suppressant to help control your cough, and guaifenesin, an expectorant that helps relieve chest congestion by thinning and loosening mucus.

This medication temporarily alleviates cough caused by minor throat and bronchial irritation, such as that which may occur with a cold, and aids in draining bronchial tubes by loosening phlegm.

Uses

If you're dealing with a cough caused by minor irritation in your throat or bronchial tubes, especially during a cold, this medication can provide temporary relief. It works by soothing your throat and helping to ease the discomfort associated with coughing.

Additionally, this medication helps to loosen phlegm (mucus) and thin out bronchial secretions, making it easier for your body to clear out mucus from your airways. This can be particularly helpful if you're feeling congested or have difficulty breathing due to mucus buildup.

Dosage and Administration

When using this medication, it's important to follow the correct dosage to ensure safety and effectiveness. For adults and children aged 12 years and older, you should take 20 milliliters (ml) every 4 hours. However, make sure not to exceed 6 doses within a 24-hour period. To measure your dose accurately, always use the dosing cup that comes with the product, and keep it handy for future use.

Please note that this medication is not suitable for children under 12 years of age, so do not use it for younger individuals. By adhering to these guidelines, you can help ensure that you use the medication safely and effectively.
