Uses for Zonatuss
Benzonatate is used to relieve coughs due to colds or influenza (flu). It is not to be used for chronic cough that occurs with smoking, asthma, or emphysema or when there is an unusually large amount of mucus or phlegm with the cough.
Benzonatate relieves cough by acting directly on the lungs and the breathing passages. It may also act on the cough center in the brain.
This medicine is available only with your doctor's prescription.
