Drug Overview

Tussin DM is a medication designed to help relieve cough and chest congestion. It contains two active ingredients: dextromethorphan HBr, which acts as a cough suppressant to temporarily alleviate coughing caused by minor throat and bronchial irritation, often associated with colds, and guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions, making it easier to drain the bronchial tubes.

This product is intended for adults and individuals aged 12 and over, and it is alcohol-free, making it a suitable option for those looking for relief from cough and chest discomfort without the effects of alcohol.

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 reducing the urge to cough, making it easier for you to feel comfortable.

Additionally, this medication helps to loosen phlegm (mucus) and thin out bronchial secretions. This means it can assist in clearing your airways, allowing for better drainage from your bronchial tubes. By doing so, it can help you breathe more easily when you're feeling under the weather.

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 mL (milliliters) 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; do not use any other measuring device.

If you are considering this medication for a child under 12 years of age, please do not use it, as it is not intended for that age group. Keep the dosing cup with the product to help you measure the correct amount each time you take it.

What to Avoid

You should avoid using this product if you are currently taking a prescription monoamine oxidase inhibitor (MAOI), which is a type of medication used for depression, psychiatric or emotional conditions, or Parkinson’s disease. Additionally, you should not use this product for at least two weeks after stopping an MAOI. If you are unsure whether your prescription includes an MAOI, please consult your doctor or pharmacist before using this product.

It's important to follow these guidelines to prevent potential serious interactions and ensure your safety. Always prioritize open communication with your healthcare provider regarding any medications you are taking.

If your cough lasts more than seven days, returns, or is accompanied by fever, rash, or a persistent headache, you should stop using the medication and consult a doctor, as these may indicate a more serious health issue.

Before using this medication, talk to your doctor if you have a cough that produces a lot of mucus, or if you have a chronic cough due to smoking, asthma, chronic bronchitis, or emphysema.
