Drug Information:
Benzonatate is a non-narcotic cough medicine. Benzonatate works by numbing the throat and lungs, making the cough reflex less active. Benzonatate is used to relieve coughing. You should not use this medication if you are allergic to benzonatate or topical numbing medicines such as Tetracaine or procaine (found in some insect bite and sunburn creams). Never suck or chew on a benzonatate capsule. Swallow the pill whole. Sucking or chewing the capsule may cause your mouth and throat to feel numb or cause other serious side effects. Learn more
