GENERIC NAME: benzonatate

BRAND NAME: Tessalon Perles; Zonatuss

DRUG CLASS AND MECHANISM: Benzonatate is a medication taken orally to suppress coughs. It has an anesthetic (numbing) action similar to that of benzocaine and numbs the stretch sensors in the lungs. It is the stretching of these sensors with breathing that causes the cough. Benzonatate begins to work within 15 to 20 minutes, and its effects last for approximately 3 to 8 hours. Benzonatate is unrelated to narcotics such as codeine which are frequently used to suppress coughs. (Another frequently used cough suppressant, dextromethorphan, which is found in many over-the-counter cough and cold preparations, is a derivative of the narcotics.)

PRESCRIBED FOR: Benzonatate is used for relieving cough.

SIDE EFFECTS: The most frequent adverse reactions of benzonatate include:
