Benzonatate is used to relieve coughing.

Benzonatate is a non-narcotic cough medicine that numbs the throat and lungs, making the cough reflex less active.

Benzonatate may also be used for purposes not listed in this medication guide.

You should not use this medicine if you are allergic to benzonatate or topical numbing medicines such as tetracaine or procaine (found in some insect bite and sunburn creams).

Tell your doctor if you are pregnant or breastfeeding.

Benzonatate is not approved for use by anyone younger than 10 years old. An overdose of benzonatate can be fatal, especially to a young child who has accidentally swallowed the medicine.
