Benzonatate Patient Tips
Medically reviewed by C. Fookes, BPharm. Last updated on Nov 13, 2018.
How it works
- Benzonatate reduces coughing by anesthetizing certain receptors located in the breathing passages and lungs, dampening down their activity and reducing the cough reflex.
- Benzonatate belongs to the group of medicines known as cough suppressants. Benzonatate may also be called an anti-tussive.
- Used to relieve a dry, irritating cough.
- Benzonatate is not a narcotic.
- Benzonatate is available as a generic.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- Sedation, headache, constipation, nausea, itchiness, skin rash, nasal congestion, a burning sensation in the eyes.
- Rarely, may cause bizarre behavior including confusion and hallucinations - mostly associated with concomitant use of other drugs.
- Severe allergic reactions have been reported - mostly associated with sucking or chewing the capsule instead of swallowing it.
- Overdosage can be fatal, especially in children.
Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

- Swallow the capsule whole. Do not suck, chew, crush, cut, or break open as this can cause overdosage.
- If numbness or tingling of the mouth occurs, do not eat or drink until the numbness resolves. Seek medical attention if it does not resolve. Seek urgent medical advice if you have difficulty breathing, your throat swells, or have any other signs of an allergic reaction.
- Only take as directed. Do not exceed a single dose of 200mg or a total daily dose of 600mg. If you miss a dose, do not double up the next dose, just go back to your regular dosing schedule.
- Keep out of reach of children. If children accidentally take benzonatate seek medical attention immediately. Signs and symptoms of overdosage include tremors, convulsions, coma, and heart attack.
- Do not give to children aged less than 10.

- Benzonatate starts to work within 15 to 20 minutes and its effects last for 3 to 8 hours.
