What are the ingredients in benzonatate?

What’s the active ingredient in benzonatate?

Benzonatate’s active ingredient is benzonatate itself.

What are the other ingredients (inactive ingredients) in benzonatate capsules?

The inactive ingredients depend on the specific product and manufacturer (and can vary by strength and formulation). Commonly, benzonatate capsules are made with a gelatin capsule shell and include ingredients such as mannitol and/or other excipients used to form the capsule and deliver the medication.

Because formulations vary, check your specific bottle or box for the exact “Inactive ingredients” line for your product (the label typically lists them). If you share the strength (e.g., 100 mg or 200 mg) and manufacturer (or a photo of the label text), I can help interpret what’s listed.

Do formulations differ by capsule strength or brand?

Yes. Even when the active drug is the same, inactive ingredients can differ by:
- Strength (100 mg vs 200 mg, for example)
- Manufacturer/brand
- Capsule shell composition or excipient suppliers

Checking the label for your exact product is the only reliable way to get the precise ingredient list.
