how long does it take for benzonatate to work

Benzonatate usually starts working within about 15 to 20 minutes after you take a dose, and its effects typically last around 3 to 8 hours. If you don’t notice relief within a day or two, or if your symptoms worsen, contact your healthcare provider. Common reasons someone takes benzonatate include a cough from a cold, bronchitis, or other respiratory infections, and it’s generally used for short-term relief (often about a week or less, depending on the doctor’s instructions). If you have any concerns about dosing, potential side effects, or interactions with other medicines, check with your clinician or pharmacist.
