Why is this medication prescribed?

Dextromethorphan is not typically prescribed by itself, but it is an over-the-counter (OTC) medication commonly found in cough and cold products. It is used to relieve coughing associated with various respiratory conditions, such as the common cold, flu, or bronchitis. Dextromethorphan is classified as a cough suppressant and works by affecting the signals in the brain that trigger the cough reflex.
