Ingredients of benzonatate?

What are the ingredients in benzonatate capsules or tablets?

Benzonatate is an active medication (an antitussive used to reduce cough). The exact “ingredients” list for a dose form depends on the brand and whether you have capsules or other formulations.

Active ingredient vs. inactive ingredients (excipients)

The active ingredient in all benzonatate products is benzonatate (the cough-suppressing drug). Inactive ingredients (excipients) commonly include things like capsule/tablet materials and other formulation components that help the drug dissolve correctly and stay stable—but the specific excipients vary by manufacturer and product.

How to check the precise ingredient list for your specific product

To see the exact ingredients for your specific benzonatate, look at:
- The box label (often includes “inactive ingredients” in smaller print or directs you to the insert), and
- The package insert / “full prescribing information” section that lists “Inactive ingredients.”

If you tell me the brand name (for example, “Tessalon Perles”), the strength (e.g., 100 mg or 200 mg), and whether it’s a capsule or tablet, I can help you pinpoint the correct ingredient list from the matching product information.
