Dextromethorphan

Dextromethorphan (DXM) is a common over-the-counter medication primarily used as a cough suppressant. It is available as a standalone drug or in combination with other ingredients in multi-symptom cold and flu medications.

DXM  primarily acts as a centrally acting antitussive, meaning it suppresses cough by targeting the brain rather than directly addressing the lungs or airways. It has multiple mechanisms of action depending on the dosage and use:

Treatment Type: Over the Counter Medication

Treatment Class: Non-opiod antitussive

Treatment Modality: Oral
