Drug Overview

Mucus DM is a medication that combines guaifenesin (an expectorant that helps loosen phlegm) and dextromethorphan hydrobromide (a cough suppressant) in extended-release tablets. It is designed to help you manage coughs and mucus associated with minor throat and bronchial irritation, such as that caused by the common cold or inhaled irritants.

By loosening mucus and reducing the urge to cough, Mucus DM makes it easier for you to clear your airways and can help you sleep better when you're feeling unwell. This product is available in a package of 20 extended-release tablets and is marketed under the brand GOOD NEIGHBOR PHARMACY.

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

Dosage and Administration

When taking this medication, it's important to swallow the tablet whole—do not crush, chew, or break it. Make sure to take it with a full glass of water, which helps the tablet dissolve properly. You can take this medication at any time, regardless of your meal schedule.

For adults and children aged 12 years and older, the recommended dosage is 1 or 2 tablets every 12 hours. However, you should not exceed 4 tablets in a 24-hour period. If you have children under 12 years of age, this medication is not suitable for them, so please avoid using it for that age group.

What to Avoid

You should avoid using this product if you are under 12 years of age. Additionally, do not take it if you are currently using a prescription monoamine oxidase inhibitor (MAOI), which is a type of medication often prescribed for depression, psychiatric conditions, or Parkinson’s disease. If you have recently stopped taking an MAOI, wait at least two weeks before using this product. If you're unsure whether your medication contains an MAOI, please consult your doctor or pharmacist.

While using this product, it’s important to follow the dosage instructions carefully and not exceed the recommended amount. Misuse or taking more than directed can lead to serious health issues, including dependence (a condition where your body becomes reliant on a substance).

Side Effects

You should be aware of some important warnings and potential side effects when using this product. It is not recommended for children under 12 years old, and you should avoid it if you are currently taking a prescription monoamine oxidase inhibitor (MAOI) or have taken one in the last two weeks. If you have a persistent cough due to smoking, asthma, chronic bronchitis, or emphysema, or if your cough is accompanied by excessive mucus, consult a doctor before using this product.

If your cough lasts more than 7 days, returns, or is accompanied by fever, rash, or a persistent headache, stop using the product and seek medical advice, as these may indicate a more serious condition. If you are pregnant or breastfeeding, it's best to consult a healthcare professional before use. Always keep this product out of reach of children, and in case of an overdose, contact medical help or a Poison Control Center immediately.
