Drug Overview

Adult Tussin Cough & Chest Congestion DM is a medication designed to help relieve cough and chest congestion for individuals aged 12 and older. It contains two active ingredients: Dextromethorphan HBr, which acts as a cough suppressant to temporarily relieve cough caused by minor throat and bronchial irritation, and Guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions, making it easier to drain the bronchial tubes.

This alcohol-free formula is comparable to the active ingredients found in Robitussin Cough + Chest Congestion DM, providing effective relief from cough and mucus buildup associated with colds.

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 10 milliliters (mL) every 4 hours, but make sure not to exceed 6 doses in a 24-hour period. To ensure accurate dosing, always use the dosing cup that comes with the product; do not use any other measuring device.

If you are caring for children, please note that this product is not intended for anyone under 12 years of age, so do not use it for younger children. Keep the dosing cup with the product to make it easy for you to measure the correct amount each time.

If you are unsure whether your prescription includes an MAOI, please consult your doctor or pharmacist before using this product.

Side Effects

You should be aware of some important side effects and warnings associated with this medication. It is crucial not to use it if you are currently taking a prescription monoamine oxidase inhibitor (MAOI), which is a type of medication used for depression or certain other conditions, or if you have stopped taking an MAOI within the last two weeks.

If your cough lasts more than seven days, returns, or is accompanied by symptoms like fever, rash, or a persistent headache, you should stop using the medication and consult a doctor, as these may indicate a more serious issue. Additionally, consult your doctor before using this medication if your cough is accompanied by excessive mucus or if you have a chronic cough due to smoking, asthma, chronic bronchitis, or emphysema.
