Dextromethorphan is a medicine found in a variety of over-the-counter (OTC) and prescription cough and cold products. It is approved for use in adults and children. However, it should not be used in children younger than two years old. This medication is commonly used to relieve minor coughing from a cold, flu, or other conditions.
In addition, dextromethorphan is also approved for use in combination with quinidine to treat pseudobulbar affect (PBA), a neurological condition that causes sudden outbursts of crying or laughing.
Healthcare providers may also occasionally recommend this drug for "off-label," or unapproved, reasons. Research has suggested that possible off-label uses (indications) for dextromethorphan may include treating nerve pain and Parkinson's disease.
