Benzonatate is a medication used to relieve coughs caused by colds, flu, and other respiratory infections. It is a non-narcotic cough suppressant that works by numbing the throat and lungs, reducing the cough reflex.
The development of benzonatate dates back to the 1950s when it was first synthesized by American chemist Paul Machmer. Machmer was working at the time for the drug company Pfizer and was tasked with developing a non-narcotic cough suppressant that would be more effective and less addictive than existing cough medicines.
After several years of research, Machmer discovered benzonatate, which he patented in 1958. Pfizer then developed and marketed the drug under the brand name Tessalon. Tessalon became available by prescription in the United States in 1958.
Since then, benzonatate has become a widely used cough suppressant and is available under various brand names, including Tessalon, Zonatuss, and others. It is considered safe and effective for most people, although it may cause side effects in some, including dizziness, drowsiness, and headache. It is important to follow the recommended dosage and to consult a healthcare provider before taking this medication.
How Is Benzonatate Used
Benzonatate is used to relieve coughs caused by colds, flu, and other respiratory infections. It is a non-narcotic cough suppressant that works by numbing the throat and lungs, reducing the cough reflex.
Benzonatate is available in capsule form and is taken orally with or without food. The capsules should not be crushed, chewed, or dissolved in the mouth as it may cause numbness or tingling in the mouth and throat.
The recommended dosage of benzonatate may vary depending on the individual’s age, medical condition, and other factors. It is important to follow the dosage instructions provided by the healthcare provider or on the label.
Benzonatate is usually taken every 8 hours, but the dosing frequency may be adjusted depending on the severity of the cough. It is important to continue taking the medication as prescribed, even if the cough improves.
Here are the general dosing guidelines for benzonatate:
For adults and children 10 years of age and older:
• The usual dosage is 100 mg to 200 mg every 8 hours, as needed, up to a maximum of 600 mg per day.
For children under 10 years of age:
• The safety and effectiveness of benzonatate have not been established in children under 10 years of age.
It is important to never exceed the recommended dose of benzonatate, as it may cause serious side effects, including seizures, confusion, and difficulty breathing. If you miss a dose of benzonatate, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed dose.
Benzonatate is generally well-tolerated, but it may cause side effects in some people, including dizziness, drowsiness, headache, and upset stomach. It is important to consult a healthcare provider if any side effects persist or worsen.

1. Allergic reactions: Some people may be allergic to benzonatate or other related medications. Signs of an allergic reaction may include hives, rash, itching, difficulty breathing, or swelling of the face, lips, tongue, or throat. If you experience any of these symptoms, seek medical attention immediately.
2. Choking and aspiration: Benzonatate capsules should not be chewed, crushed, or dissolved in the mouth as it may cause numbness or tingling in the mouth and throat, leading to choking and aspiration (inhaling food, liquids, or medication into the lungs). This can be a life-threatening condition.

6. Children: The safety and effectiveness of benzonatate have not been established in children under 10 years of age. Use in this population is not recommended.
7. Elderly: Elderly patients may be more sensitive to the effects of benzonatate, especially drowsiness and dizziness. Use caution when taking this medication in older adults.
8. Lung disease: Benzonatate may worsen certain lung conditions, including asthma, chronic obstructive pulmonary disease (COPD), and emphysema. Consult your healthcare provider before taking this medication if you have any underlying lung conditions.
9. Seizures: Benzonatate may lower the seizure threshold in some people, increasing the risk of seizures. Consult your healthcare provider before taking this medication if you have a history of seizures or epilepsy.
10. Overdose: Taking too much benzonatate can be dangerous and may cause serious side effects, including seizures, confusion, and difficulty breathing. Seek medical attention immediately if you suspect an overdose.
It is important to discuss any medical conditions, medications, or supplements you are taking with your healthcare provider before taking benzonatate. If you experience any unusual symptoms or side effects while taking this medication, contact your healthcare provider immediately.
