Description
Dextromethorphan (DMR) is a widely used over-the-counter (OTC) medication primarily utilized as a cough suppressant. It works by affecting the signals in the brain that trigger the cough reflex. Dextromethorphan is commonly included in various cold and cough preparations, often in combination with other ingredients like antihistamines, decongestants, or expectorants. It is typically used to treat a dry, non-productive cough, helping to alleviate persistent coughing associated with conditions such as the common cold, influenza, or respiratory infections.
While it does not treat the underlying causes of coughing, Dextromethorphan can significantly reduce the frequency and severity of coughing, making it useful for symptom relief. It is also considered to have some mild sedative properties.
