Is there a generic version of Tessalon Perles (benzonatate)?
Yes. Tessalon Perles is the brand name for benzonatate, and generic benzonatate is available. Tessalon Perles is used as a cough suppressant, and the generic is typically prescribed as “benzonatate” rather than “Tessalon Perles.”
What does “generic Tessalon Perles” mean at the pharmacy?
At the pharmacy, “generic Tessalon Perles” usually means a product labeled benzonatate (the active ingredient) in similar capsule formulations and strengths. The key thing to match is the active ingredient (benzonatate) and the dose, which is typically listed on the bottle as mg per capsule.
Are the capsules interchangeable if the mg strength matches?
In most cases, yes: if the generic has the same active ingredient (benzonatate) and the same strength (mg) and dosing instructions, it should be interchangeable for the purpose of cough suppression. What can differ between brands/generics is the capsule appearance and excipients, not the active drug amount.
Why would a doctor specify “Tessalon Perles” instead of generic?
Clinicians sometimes specify the brand for consistency if a patient has had problems with a specific formulation, or if there are pharmacy substitution restrictions. But medically, generic benzonatate is designed to be equivalent to the brand product when the dose and instructions are the same.
How to ask for the right generic
Ask for “benzonatate capsules” and confirm the mg strength on your prescription. If you tell the pharmacy which strength you’re taking (for example, “100 mg” or “200 mg”), they can match the closest equivalent.
