Is benzonatate an opioid?

No. Benzonatate is not an opioid. It’s a non-opioid antitussive (cough suppressant) that works by numbing the stretch receptors in the lungs to reduce coughing.

Common side effects can include dizziness, drowsiness, nausea, or numbness of the mouth/throat if the capsule is chewed or dissolved in the mouth. Do not chew or crush the capsules and seek medical attention if you have trouble breathing, severe allergic reactions, or signs of overdose. If you have specific health concerns or are pregnant/nursing, check with a clinician.
