Coughing can be a significant annoyance, disrupting daily activities and sleep. For many, finding an effective cough suppressant is essential to managing symptoms. Benzonatate, a prescription medication, is a popular choice for relieving cough. In this blog, we'll explore its uses, side effects, and other essential information you need to know about this medication
What is Benzonatate?
Benzonatate is a non-narcotic oral antitussive (cough suppressant) used to relieve coughing. It works by numbing the throat and lungs, making the cough reflex less active. It is typically prescribed for adults and children over the age of 10.
How Does Benzonatate Work?
Benzonatate belongs to a class of drugs known as antitussives. It works by anesthetizing (numbing) the stretch receptors located in the respiratory passages, lungs, and pleura (the membrane surrounding the lungs). By doing so, it reduces the cough reflex at its source, providing relief from persistent coughing.
Uses of Benzonatate
Benzonatate is primarily used for the relief of cough caused by:
- Common Cold
- Bronchitis
- Pneumonia
- Asthma
- Emphysema
- Other Respiratory Conditions
It is not intended for use in treating coughs that result from smoking, asthma, or emphysema unless specifically directed by a doctor.
Dosage and Administration
Dosage
The typical dosage for adults and children over 10 years of age is:
- 100 mg to 200 mg three times a day as needed for cough.
It is crucial not to exceed the prescribed dosage, as doing so can lead to serious side effects or overdose.
Administration
- Benzonatate capsules should be swallowed whole with water.
- Do not chew, crush, or dissolve the capsules in your mouth, as this can cause numbness in the mouth and throat, leading to choking or other severe reactions.
