Benzonatate: Uses, Dosage, Side Effects, and More

Benzonatate is a prescription medication widely used to relieve cough. Its effectiveness and minimal sedative properties make it a popular choice for patients seeking relief without drowsiness. This guide provides detailed information on Benzonatate, including its uses, dosage, side effects, interactions, and benefits.

What is Benzonatate?

Benzonatate is a non-narcotic antitussive (cough suppressant). It works by numbing the throat and lungs, reducing the cough reflex at its source. Unlike opioids used for cough, Benzonatate does not have sedative or addictive properties, making it a safer alternative for many patients.

Uses of Benzonatate

1. Cough Relief:

• Prescribed for managing coughs caused by colds, respiratory infections, or other conditions like bronchitis.

2. Non-Sedative Option:

• Ideal for patients who need cough relief without experiencing drowsiness.

3. Adjunctive Therapy:

• Used alongside other medications to manage respiratory conditions involving persistent cough.

Dosage of Benzonatate

Adults and Children Over 10 Years:

• Standard Dose: 100 mg to 200 mg taken orally three times daily as needed.
• Maximum daily dose: Do not exceed 600 mg in 24 hours.

Administration Instructions:

• Swallow capsules whole with water. Do not chew, crush, or dissolve the capsule, as this can cause oral and throat numbness or choking.

Important: Benzonatate is not recommended for children under 10 years due to the risk of severe side effects, including accidental overdose.
