Benzonatate: Understanding This Non-Narcotic Cough Suppressant

Benzonatate is a prescription medication primarily used to relieve coughs. Unlike many other cough medications, it is a non-narcotic antitussive, meaning it does not contain opioids and works through a different mechanism to alleviate coughing fits.

What is Benzonatate?

Benzonatate is an oral capsule that belongs to a class of drugs called non-narcotic antitussives. It is commonly prescribed for the symptomatic relief of cough due to colds, flu, bronchitis, pneumonia, or irritation of the respiratory tract and lungs. It is available by prescription only and is known by its brand name, Tessalon Perles, among others.

How Benzonatate Works

Benzonatate works by anesthetizing the stretch receptors located in the respiratory passages, lungs, and pleura (the membranes surrounding the lungs). When these receptors are numbed, the cough reflex is suppressed, leading to a reduction in the urge to cough. This localized anesthetic action is what distinguishes it from centrally acting cough suppressants.

Uses and Indications

The primary use of Benzonatate is for the relief of cough. It is indicated for the treatment of various acute and chronic cough conditions, including:


  • Cough associated with the common cold or flu

  • Cough due to bronchitis

  • Cough related to pneumonia

  • Irritation of the respiratory tract

  • Other conditions where cough relief is desired by a healthcare professional

It is important to note that Benzonatate treats the symptom of coughing and not the underlying cause of the cough.

Dosage and Administration

Benzonatate is typically taken orally, usually three times a day as needed for cough. The capsules should be swallowed whole and not chewed, crushed, or dissolved. Chewing or crushing the capsules can lead to a sudden release of the medication, which can cause numbing of the mouth, throat, and esophagus, potentially leading to choking or severe allergic reactions.

Important Considerations


  • Always follow your doctor's instructions regarding dosage and duration of treatment.

  • Do not exceed the prescribed dose.

  • If a dose is missed, take it as soon as you remember, unless it is almost time for your next scheduled dose. Do not double doses.

  • Store Benzonatate at room temperature, away from moisture and heat, and out of reach of children.

Potential Side Effects

Like all medications, Benzonatate can cause side effects, although not everyone experiences them. Common side effects may include:


  • Drowsiness or dizziness

  • Headache

  • Nausea or upset stomach

  • Constipation

  • Skin rash or itching

More serious, but less common, side effects can occur, especially if the capsules are chewed or dissolved. These include severe allergic reactions, bronchospasm, laryngospasm, and circulatory collapse. If you experience severe side effects or signs of an allergic reaction (e.g., hives, difficulty breathing, swelling of your face, lips, tongue, or throat), seek immediate medical attention.

Precautions and Warnings

Before taking Benzonatate, inform your doctor about all your medical conditions and any other medications you are taking, including over-the-counter drugs, vitamins, and herbal supplements. Special care should be taken with individuals who have a history of allergic reactions to local anesthetics like procaine or tetracaine, as Benzonatate is chemically related to these substances.

Benzonatate should be used with caution in pregnant or breastfeeding women, and its use should only be considered if the potential benefits outweigh the risks. It is not approved for use in children younger than 10 years of age due to the risk of accidental overdose and fatal events if the capsules are ingested whole or broken.

Who Should Avoid Benzonatate?

Individuals with known hypersensitivity to Benzonatate or related local anesthetic agents should avoid this medication. It is also contraindicated for children under 10 years old due to the risk of accidental overdose and potential for fatal events if capsules are broken or ingested improperly.

Conclusion

Benzonatate offers an effective, non-narcotic option for relieving troublesome coughs caused by various respiratory conditions. By understanding its mechanism of action, proper administration, and potential side effects, patients can use this medication safely under the guidance of a healthcare professional. Always consult your doctor for personalized medical advice and to determine if Benzonatate is the right treatment for your specific condition.
