Benzonatate ingredients?

Benzonatate is the brand name/active drug in benzonatate capsules (commonly prescribed for cough). The key “ingredient” is:

• Active ingredient: Benzonatate (often present as benzonatate USP)
  
  Because the exact inactive (non-medicinal) ingredients vary by manufacturer and product strength, I can’t name them precisely without the specific label/brand.
  
  If you tell me the brand name (e.g., Tessalon Perles) and strength (e.g., 100 mg or 200 mg), or paste the “inactive ingredients” line from the box, I can list everything included.
