Benzonatate Is a Prescription Cough Suppressant That Works by Numbing the Cough Reflex in Your Lungs

If your doctor has prescribed Benzonatate — or you're wondering whether it might help your persistent cough — this guide covers everything you need to know. We'll walk through what it is, how it's used, proper dosing, important safety information, and what it costs in 2026.

What Is Benzonatate?

Benzonatate is a non-narcotic prescription cough suppressant (antitussive). It was originally sold under the brand names Tessalon and Tessalon Perles by Pfizer, though the brand-name version has been largely discontinued. Today, Benzonatate is available exclusively as an affordable generic, manufactured by companies including Amneal, Ascend Laboratories, Sun Pharma, and Teva.

Unlike opioid-based cough suppressants like Codeine, Benzonatate is not a controlled substance. It doesn't carry the risk of dependence or abuse associated with narcotic cough medicines. It belongs to the antitussive drug class and is chemically related to local anesthetics like Tetracaine.

Benzonatate was approved by the FDA for the symptomatic relief of cough. It comes in three strengths:

• 100 mg oral capsule
• 150 mg oral capsule
• 200 mg oral capsule

What Is Benzonatate Used For?

Benzonatate is FDA-approved for one purpose: symptomatic relief of cough. It doesn't treat the underlying cause of your cough — it suppresses the cough reflex so you can rest and recover more comfortably.

Doctors commonly prescribe it for:

• Persistent dry cough from upper respiratory infections (colds, flu)
• Cough associated with bronchitis
• Post-nasal drip cough
• Cough suppression before medical procedures (like bronchoscopy or intubation)

Benzonatate works best for dry, non-productive coughs. If your cough is producing a lot of mucus, your doctor may recommend a different approach — like an expectorant such as Guaifenesin (Mucinex) — or use Benzonatate alongside other treatments.

How Is Benzonatate Taken?

Benzonatate is taken orally, usually 100 mg to 200 mg three times daily as needed. The maximum daily dose is 600 mg (three 200 mg capsules).

Critical instructions for taking Benzonatate:

• Swallow capsules whole with a full glass of water.
• Never chew, suck, crush, or break open the capsule. Benzonatate is a local anesthetic — if the contents are released in your mouth or throat, it can cause numbness leading to choking, laryngospasm (throat closing), bronchospasm, and potentially cardiovascular collapse.
• Take with or without food. If it causes stomach upset, try taking it with a small meal.
• Store at room temperature away from moisture, heat, and light.
• Keep out of reach of children. Even 1–2 capsules can be fatal in children under 10.

If you miss a dose, take it as soon as you remember — unless it's close to time for your next dose. Never double up.

Who Should Not Take Benzonatate?

Benzonatate is not safe for everyone. Do not take it if you have:

• A known allergy to Benzonatate or any of its ingredients
• An allergy to related local anesthetics such as Tetracaine or Procaine (often used in dental procedures)

Benzonatate is not approved for children under 10 years old. Accidental ingestion in young children has resulted in fatalities. The capsules resemble candy, making safe storage critical.

For pregnant or breastfeeding women, safety has not been established. Consult your doctor before use.

Older adults should use caution due to increased sensitivity to drowsiness and dizziness. For a complete overview of side effects, see our guide on Benzonatate side effects.

How Much Does Benzonatate Cost?

One of Benzonatate's biggest advantages is its affordability. As a widely available generic, it's one of the least expensive prescription cough medications on the market.

Here's what you can expect to pay in 2026:

• With insurance: Most plans cover Benzonatate as a Tier 1 generic with copays of $0–$10. Prior authorization is rarely required.
• Cash price (no insurance): Ranges from $7 to $65 for 30 capsules (100 mg), depending on the pharmacy.
• With a discount coupon: As low as $4–$10 for 30 capsules using GoodRx, SingleCare, or RxSaver.

Because it's a generic with multiple manufacturers, prices are competitive. The 200 mg capsules typically cost $9.50–$12 for 30 capsules.

Final Thoughts

Benzonatate is a safe, effective, and affordable option for managing persistent cough. It's not a narcotic, it doesn't cause dependence, and it works quickly. The most important thing to remember is to always swallow the capsule whole and keep it away from young children.
