Does benzonatate expire?

Yes. Benzonatate, like other meds, has an expiration date printed on the bottle or blister pack.

- After the expiration date, the manufacturer can’t guarantee full potency or safety.
- Do not use benzonatate that is past its expiration.

What to do with expired benzonatate:
- Dispose of it safely. Do not flush it down the toilet.
- If there’s a take-back program in your area, use that. If not:
- Mix the pills with something undesirable (e.g., coffee grounds, dirt, or cat litter) in a sealed bag or container.
- Place the sealed bag in the trash.
- Remove or scratch out personal information from the label before disposing.
- Keep new benzonatate in its original container, stored at room temperature, away from moisture and heat, and out of reach of children and pets.

If you’re unsure about the expiration date or how to dispose of it, ask a pharmacist for guidance.
