Benzonatate is a medication primarily used for the symptomatic relief of cough. It is a non-narcotic oral antitussive that works by numbing certain areas in the lungs and airways, reducing the urge to cough. Benzonatate acts as a local anesthetic that decreases the sensitivity of stretch receptors in the respiratory tract, which suppresses the cough reflex. It is commonly prescribed for coughs caused by colds, influenza, bronchitis, pneumonia, asthma, and other respiratory conditions. It is not typically used for chronic coughs that involve high mucus or phlegm levels such as those caused by smoking or chronic obstructive pulmonary disease (COPD). Benzonatate can also be used to suppress hiccups and sometimes during medical procedures like intubation to numb the throat. The medication takes effect within 15 to 20 minutes after oral administration and its effects last between 3 and 8 hours. Benzonatate does not treat the underlying cause of the cough but helps reduce cough frequency and intensity for patient comfort.
