Drug Overview

Mucus Relief DM is a medication designed to help you manage cough and mucus associated with common colds or inhaled irritants. It contains two active ingredients: guaifenesin (an expectorant) and dextromethorphan HBr (a cough suppressant). Guaifenesin works by loosening phlegm and thinning bronchial secretions, making it easier to clear mucus from your airways. Meanwhile, dextromethorphan helps to temporarily relieve the urge to cough, allowing you to rest more comfortably.

This extended-release tablet formulation is intended to provide relief from cough due to minor throat and bronchial irritation, helping to reduce the intensity of coughing and the impulse to cough, especially at night.

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 also use this medication to temporarily relieve coughs caused by minor throat and bronchial irritation, which can happen with the common cold or from inhaling irritants. It can help reduce the intensity of your cough and 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 one tablet every 12 hours. However, you should not take more than two 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

It's important to be cautious when using this product. You should not use it if you are under 12 years of age or if you are currently taking a prescription monoamine oxidase inhibitor (MAOI), which is a type of medication used for depression, psychiatric conditions, or Parkinson's disease. Additionally, you should wait at least two weeks after stopping an MAOI before using this product. If you're unsure whether your medication contains an MAOI, please consult your doctor or pharmacist.

If you have a persistent cough due to smoking, asthma, chronic bronchitis, or emphysema, or if your cough is accompanied by excessive mucus, consult your doctor before use.

While using this product, make sure to follow the dosage instructions carefully. If your cough lasts more than seven days, returns, or is accompanied by fever, rash, or a persistent headache, stop using the medication and seek medical advice, as these may indicate a more serious condition.
