Drug Overview

TUSSIN DM MAX is a maximum strength cough syrup designed for adults and is suitable for those aged 12 and over. It contains two active ingredients: dextromethorphan HBr, which acts as a cough suppressant to help control your cough, and guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions. This combination temporarily relieves cough caused by minor throat and bronchial irritation, such as that which may occur with a cold, while also relieving chest congestion.

This non-drowsy formula is available in an 8 FL OZ bottle and comes in a pleasant raspberry and menthol flavor, making it easier to take. TUSSIN DM MAX works by helping to clear mucus from your airways, allowing you to breathe more comfortably.

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 drain the bronchial tubes. This can be particularly helpful when you're feeling congested and need to clear your airways.

Dosage and Administration

When using this medication, it's important to follow the dosing instructions carefully. 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 ensure accurate dosing, always use the dosing cup that comes with the product, and keep it handy for each use.

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

Warnings and Precautions
