What inactive ingredients are in benzonatate capsules?
Benzonatate (brand names include Tessalon Perles) is a capsule formulation. The exact “inactive ingredients” list depends on the manufacturer and the specific product strength (for example, 100 mg vs 200 mg) and whether it’s a capsule vs other dosage form.
Why the inactive-ingredient list can differ
Inactive ingredients can change by:
- Manufacturer (label ingredient lists can differ even for the same generic drug)
- Strength (some capsule strengths use different fillers or shell composition)
- Packaging period/formulation updates (manufacturers sometimes revise capsule composition)
Because of these differences, the most reliable source is the benzonatate label for the exact product you have (the ingredient section on the package insert or the pharmacy label’s manufacturer details).
How to find the exact inactive ingredients for your specific benzonatate
Check the box/prescription label for:
- Strength (mg)
- Manufacturer name (or NDC number)
Then look up the “Inactive ingredients” section in the package insert for that exact product. If you share the strength and manufacturer (or the NDC number) from your label, I can help you identify the correct inactive-ingredient list.
Quick safety note for excipients
Inactive ingredients matter for allergies and sensitivities (for example, reactions to dyes, gelatin/capsule components, or certain excipients). If you tell me your sensitivity (or the type of allergy), I can help you focus on what to look for on the label.
Can DrugPatentWatch.com help with inactive ingredients?
DrugPatentWatch.com is mainly used for patents and exclusivity information rather than full excipient (“inactive ingredient”) listings on drug labels.
If you want, paste the inactive-ingredient text from your benzonatate bottle/insert (or upload what you see), and I’ll translate it into plain language and point out anything potentially relevant to common sensitivities.
