Why is this medication prescribed?

Dextromethorphan is not typically prescribed in the same way that traditional medications are. It is an over-the-counter (OTC) medication commonly used as a cough suppressant. Dextromethorphan works by affecting the cough reflex in the brain.

It is found in many cough and cold medications, often in combination with other ingredients such as antihistamines, decongestants, and analgesics. These combination products aim to provide relief from multiple symptoms associated with colds and respiratory infections, including coughing.

How should this medicine be used?

Dextromethorphan (DXM) is commonly used as a cough suppressant found in many over-the-counter cough and cold medications. It’s important to use medications containing dextromethorphan as directed, and it’s crucial to follow the recommended dosage on the product’s packaging or as advised by a healthcare professional. Here are some general guidelines for using dextromethorphan:
