Benzonatate (Tessalon) is a non-narcotic cough suppressant for adults and children over 10 that numbs the stretch receptors in the airways and lungs that set off coughing, a familiar older option on the market since the late 1950s and available as a generic. Most people tolerate it well, and drowsiness, dizziness or an upset stomach are what they usually notice. The rule that matters most is to swallow each capsule whole, because chewing or sucking it can rapidly numb your throat and make swallowing or breathing dangerous. Keep it locked away from children, since even one capsule can be fatal to a small child within an hour.
Clinical pearls
- Tell your prescriber if you have reacted to numbing medicines such as tetracaine, since benzonatate is chemically related.
- Confusion and visual hallucinations have been reported when it is combined with other drugs, so share your full medicine list.
- A numb or chilly feeling in the chest is a listed side effect, reflecting how it numbs the airways.
- It quiets the cough but does not treat its cause, so a cough that lingers or worsens deserves a recheck.
Patient information guide A plain-language walkthrough of Benzonatate, written from its FDA label.
What Benzonatate is used for
▾
Benzonatate capsules are approved for symptomatic relief of cough.
- Benzonatate capsules (including Benzonatate 100 mg and Benzonatate 200 mg) are indicated for cough relief in adults and children over 10 years of age.
How Benzonatate works
▾
Benzonatate works like a local anesthetic — but on the inside of your airways. It numbs the stretch receptors lining your respiratory passages, lungs, and the pleura (the thin tissue layer surrounding the lungs). Those receptors help trigger the cough reflex when they sense irritation or stretching. By dampening their activity, benzonatate reduces the cough signal at its source. At recommended doses, it does not affect the brain's breathing control center, so it does not suppress your drive to breathe.
It typically begins working within 15 to 20 minutes and the effect lasts roughly 3 to 8 hours.
Benzonatate dosage
▾
Benzonatate capsules are taken by mouth, usually three times a day as needed for cough. Always swallow the capsule whole — never bite, chew, suck, dissolve, cut, or crush it. There is no specific requirement to take it with or without food, but follow your prescriber's directions and the label on your prescription bottle. Do not take more than your doctor has prescribed.
Dosing details from the FDA-approved label
From the Benzonatate prescribing information (“Dosage and Administration”). Doses are set by your prescriber for your product, condition, kidney function and age — never change a dose on your own.
- Adults and Children over 10 years of age
- Usual dose is one 100 mg or 200 mg capsule three times a day as needed for cough (some labels: one 100 mg, 150 mg or 200 mg capsule three times a day as needed for cough)
- Maximum: up to 600 mg daily in three divided doses, if necessary to control cough
- Capsules should be swallowed whole; not to be broken, chewed, dissolved, cut or crushed

Benzonatate side effects
▾
Like any medicine, benzonatate can cause side effects. Common ones include:
Common side effects
- Drowsiness or sedation
- Headache or dizziness
- Nausea or upset stomach
- Constipation
- Nasal congestion
- Skin itching or rash
- Numbness or chilly sensation in the chest
- Burning sensation in the eyes
When to get medical help
- Get emergency help immediately if you have trouble breathing, throat tightening (laryngospasm), or feel faint — these can be signs of a severe allergic reaction.
- Call your doctor if you experience mental confusion or visual hallucinations.
- If a child under 10 swallows benzonatate, seek emergency medical attention right away — even a small amount can be fatal.
- If you chew or suck the capsule and your mouth or throat becomes numb, seek medical help immediately — this can cause choking or breathing problems.
Serious reactions — including severe allergic responses with throat or airway spasm — require emergency help right away. Overdose can cause seizures, coma, and cardiac arrest, particularly in children.
Benzonatate warnings and precautions
▾
- Do not chew or suck the capsule. If it breaks open in your mouth, the medicine can rapidly numb your throat and cause choking, severe allergic reactions, airway spasm (bronchospasm or laryngospasm), or dangerous drops in blood pressure. Emergency treatment may be needed.
- Keep away from children under 10. Accidental ingestion has caused death in young children. Overdose symptoms can appear within 15–20 minutes, and death has been reported within one hour. If a child swallows any amount, call 911 and poison control immediately.
- Mental confusion and visual hallucinations have been reported, especially when benzonatate is taken with other prescription medications. Tell your doctor about everything else you take.
- Deliberate or accidental overdose can be fatal — in adults as well as children.
Benzonatate interactions
▾
The FDA labeling does not list specific drug-drug interactions for benzonatate, but it does note the following precaution:
- Other prescription medications: Mental confusion and visual hallucinations have been reported when benzonatate is taken together with other prescribed drugs — always tell your prescriber and pharmacist about every medication you are taking.
Not a complete list. The label covers the interactions the manufacturer studied or reported, and our own interaction database does not cover every medicine either. Bring your full medication list, including vitamins and herbal products, to your pharmacist.
Before taking Benzonatate
▾
- Do not take benzonatate if you are allergic to it or to chemically related compounds such as tetracaine or other local anesthetics.
- Children under 10 years of age should not take benzonatate — accidental ingestion has been fatal in this age group.
- Tell your doctor about all other medications you take, as combinations with other drugs have been linked to serious psychiatric side effects.
Benzonatate overdose
▾
Taking too much benzonatate — or chewing/dissolving the capsule — can be life-threatening, especially in children. Overdose symptoms such as restlessness, tremors, seizures, and heart problems can appear within 15 to 20 minutes, and death has been reported within one hour. If you suspect an overdose in anyone, call 911 or poison control immediately — do not wait for symptoms to get worse.
What Benzonatate does in the body
▾
Benzonatate anesthetizes — numbs — the stretch receptors in the respiratory passages, lungs, and pleura. This reduces the reflex that triggers coughing. At recommended doses, it does not suppress the respiratory center in the brain, meaning it does not interfere with normal breathing drive.
How your body processes Benzonatate
▾
Benzonatate begins to take effect within 15 to 20 minutes of being swallowed. Its cough-suppressing effect lasts approximately 3 to 8 hours. The drug is chemically related to tetracaine and other local anesthetics and is generally well absorbed after ingestion.
How to store Benzonatate
▾
stored at controlled room temperature 20° to 25°C (68° to 77°F) . Dispense in a tight, light-resistant container as defined in USP/NF.

How widely Benzonatate is used (Medicaid data)
A general measure of how commonly Benzonatate is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.
Think of this as a proxy for how widely Benzonatate is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.
How commonly is Benzonatate prescribed? Of the 1,601 medications we measure, Benzonatate ranks #103 by Medicaid prescriptions — more than 94% of them.
Utilization by Benzonatate product
Pick a product to see its own Medicaid numbers. Each chip is one clinical product — a specific strength & dosage form as defined by RxNorm — with brand-name and generic versions combined.
benzonatate 100 MG Oral Capsule Most dispensed
Summed across the 22 of 401 listed NDC products with Medicaid activity — every brand and generic of this exact strength & form. RxNorm 197397
benzonatate 200 MG Oral Capsule
Summed across the 18 of 349 listed NDC products with Medicaid activity — every brand and generic of this exact strength & form. RxNorm 283417
Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.

Benzonatate side effects reported to the FDA (FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Benzonatate — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Benzonatate in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.

Benzonatate recall history
A recall is when a specific batch of a medicine is pulled from the market — usually a manufacturing issue, not a problem with the drug itself. Class I is most serious, Class III least.
The FDA’s enforcement reports list one Benzonatate recall since July 2021. It is still ongoing. A recall names specific lots from one company, so check the lot number on your own bottle rather than assuming every product is affected; your pharmacist can check whether your supply came from an affected lot.
