Non-Narcotic Cough Suppressant
Benzonatate
Tessalon Perles
Benzonatate works by numbing the stretch receptors in your lungs and airways — the sensors that trigger the cough reflex. Think of it like a local anesthetic for your cough.
Reviewed by Chris Woods, MSN, APRN, FNP-C — Licensed Nurse Practitioner. This guide is written in plain language to help you understand how benzonatate works, how to take it safely, and what to watch for.
What Is Benzonatate?
Benzonatate is a non-narcotic cough suppressant that's been helping people manage persistent coughs for decades. It's sold under the brand name Tessalon Perles — those little pearl-shaped capsules you swallow whole.
Unlike narcotic cough medicines, benzonatate doesn't affect your central nervous system or carry the risk of addiction. Instead, it does something unique: it numbs the specialized sensors in your lungs and airways called stretch receptors. These receptors are what tell your brain that you need to cough. When they're numbed, the urge to cough goes away — without making you drowsy or affecting your ability to think clearly.
Drug Class: Non-narcotic Antitussive (Cough Suppressant)
Generic Name: Benzonatate
Brand Name: Tessalon Perles
How You Take It: Capsule by mouth
What Does Benzonatate Treat?
Benzonatate is prescribed for one thing: symptomatic relief of coughs. It helps suppress dry, tickling coughs caused by colds, flu, bronchitis, and other upper respiratory conditions.
Important: Benzonatate only suppresses the cough. It doesn't treat the underlying cause. If your cough persists for more than a week or is getting worse, contact your provider to find out what's really going on.
How to Take Benzonatate
The most important thing about benzonatate is how you take it. Getting this right is critical for safety and effectiveness.
Dosing Information
Details
Typical Dose
100–200 mg three times daily as needed
Maximum Daily Dose
600 mg per day (3 doses of 200 mg)
How to Take It
Swallow whole with water — NEVER chew, crush, dissolve, or suck on the capsules
With Food?
Can take with or without food
How Long?
Short-term use only — typically 3–7 days
Critical Safety Warning: This is the most important thing about benzonatate: swallow it whole. If the gel leaks out, it can numb your entire mouth and throat, which can lead to choking. This is especially dangerous for children.
Why Swallowing Whole Matters:
The capsule protects the numbing agent from reaching your mouth and throat
If you chew or break it, the benzonatate numbs your mouth and tongue instead of your lungs
This mouth numbness interferes with your ability to swallow safely and can cause choking
For children, even small amounts leaking can be dangerous
Pro Tip: Take benzonatate with a full glass of water to help it go down easily. If you're having trouble swallowing capsules, talk to your provider — they may need to switch you to a different cough medicine.
Side Effects
Benzonatate is generally well-tolerated, but like all medications, it can cause side effects. Most are mild and go away on their own.
Common Side Effects
Drowsiness or dizziness
Headache
Mild nausea
Nasal congestion
Constipation
Burning or stinging in your mouth (if capsule is damaged)
Serious Side Effects (Call Your Provider)
Severe allergic reaction (rash, hives, swelling, difficulty breathing)
Choking or difficulty swallowing
Numbness of your mouth or throat that doesn't go away
Confusion or difficulty concentrating
Visual disturbances or blurred vision
Severe dizziness or loss of consciousness
Mild side effects like drowsiness or headache are usually temporary. If they don't improve after a day or two, or if they interfere with your daily life, talk to your provider about other options.
Red Flags: When to Seek Help Immediately
Stop taking benzonatate and get emergency help if you experience any of these:
Numbness in your mouth or throat: Spit out the capsule immediately and rinse your mouth with water. Do not swallow.
Difficulty swallowing or choking sensation: This means the benzonatate reached your throat instead of staying in the capsule.
Severe allergic reaction: Rash, hives, facial swelling, or difficulty breathing — get emergency help right away.
Confusion, visual disturbances, or loss of consciousness: These suggest serious central nervous system effects.
Overdose symptoms in children: Tremors, seizures, or loss of consciousness — call Poison Control (1-800-222-1222) immediately.
Critical Warnings & Precautions
Know these important safety points before taking benzonatate.
NEVER CHEW THE CAPSULE
This is the most important thing about benzonatate: swallow it whole. If the gel leaks out, it can numb your entire mouth and throat, which can lead to choking. This is especially dangerous for children.
Keep Away from Children: Benzonatate is dangerous for young children. Overdose in kids can be fatal. It's not approved for children under 10, and even then, only with careful monitoring.
Pregnancy: Benzonatate is Category C for pregnancy, meaning there isn't enough research to confirm it's safe during pregnancy. Only use it if the benefits clearly outweigh the risks, and only under your provider's direction.
Other Medications: Tell your provider about all other medications you're taking, especially cough medicines, cold remedies, or sleep aids — combining them could increase drowsiness or other side effects.
Liver or Kidney Problems: If you have liver or kidney disease, tell your provider. You may need a lower dose or a different medication altogether.
Frequently Asked Questions
Why can't I chew benzonatate?▼
Chewing benzonatate releases the gel inside the capsule, which numbs your mouth and throat. This numbness can interfere with your swallowing reflex and cause choking. The gel is designed to reach your lungs whole, where it numbs the stretch receptors that trigger coughing. Always swallow the capsule completely intact.
How quickly does benzonatate stop a cough?▼
Most people feel relief within 15–30 minutes of taking benzonatate. The full effect peaks around 1 hour. But remember, it only suppresses the cough reflex — it doesn't treat the underlying cause. If your cough persists beyond a week or gets worse, talk to your provider.
Can I take benzonatate with other cough medicine?▼
It's best to avoid combining benzonatate with other cough suppressants or over-the-counter cold medicines without talking to your provider first. Too much cough suppression can be harmful, and some combinations might increase drowsiness or dizziness.
How long can I take benzonatate?▼
Benzonatate is meant for short-term use — typically a few days to a week. Don't take it for more than 7–10 days without checking in with your provider. If your cough hasn't improved by then, you need to find out what's really going on.
Can I give benzonatate to my child?▼
No. Benzonatate is not approved for children under 10 years old, and even then, only with careful monitoring. Overdose in young children can be serious and even fatal. If your child has a persistent cough, talk to their pediatrician about safe options.
