Does benzonatate have alcohol in it?

Generally no. The common benzonatate products (the soft gelatin capsules like Tessalon Perles) do not list alcohol as an ingredient. The capsule shell is made of gelatin and glycerin, with benzonatate as the active ingredient and other inactive ingredients.

If you’re using a liquid cough medicine or another formulation that contains benzonatate, it could have alcohol or other solvents listed on the label. Always check the specific product’s ingredient list or package insert, or ask your pharmacist if you’re unsure.
