What does benzonatate do?

Benzonatate is a non-narcotic cough suppressant (antitussive). It works by numbing the stretch receptors in the lungs and airways, which reduces the cough reflex. It doesn’t treat the underlying cause of a cough; it just helps lessen coughing.

Quick notes:
- How it’s used: Common adult dose is 100 mg by mouth three times daily (max about 600 mg/day). Swallow capsules whole; don’t chew or dissolve in the mouth.
- Who should avoid or use with caution: Not recommended for children under about 10 years old. Tell your doctor if you’re pregnant or breastfeeding, have liver/kidney disease, or take other sedating medicines.
- Common side effects: Drowsiness, dizziness, headache, upset stomach, or numbness/tingling in the mouth or throat (if you chew or crush the capsule).
- Other safety: Avoid alcohol or other sedatives that can increase drowsiness. If your cough lasts more than a week or is accompanied by fever, rash, shortness of breath, or chest pain, seek medical advice.

If you’re taking benzonatate or considering it, and you have specific questions (dose adjustments, interactions with other meds, or dosing for a child), tell me more about your situation and I can help.
