Doctors prescribe benzonatate primarily to relieve cough, especially when it is persistent, bothersome, or interfering with a patient's comfort and daily life.
How Benzonatate Works
Benzonatate belongs to a class of medications known as antitussives, which are designed to suppress coughing. Its mechanism of action involves reducing the cough reflex within the lungs and air passages. By numbing these areas, it helps to diminish the urge to cough, providing relief to the patient.
Key Reasons for Prescription
Healthcare providers opt for benzonatate for several reasons when managing a patient's cough:
- Symptom Relief: The most direct reason is to alleviate the discomfort and irritation caused by a persistent cough. This is particularly useful for dry, hacking coughs that don't produce mucus but are highly irritating.
- Improved Sleep: A chronic cough can severely disrupt sleep patterns, leading to fatigue and reduced quality of life. By suppressing the cough reflex, benzonatate can help patients achieve more restful sleep.
- Enhanced Comfort: Reducing the frequency and intensity of coughing spells can significantly improve a patient's overall comfort, allowing them to participate in daily activities more easily.
- Prevention of Complications: Excessive coughing can sometimes lead to complications such as chest pain, hoarseness, exhaustion, or even aggravation of other medical conditions. Suppressing the cough can help prevent these issues.
- Specific Cough Types: It's often prescribed for non-productive coughs associated with conditions like:
- Common cold
- Bronchitis
- Post-nasal drip
- Flu
- Other respiratory irritations
When Benzonatate is Considered
Doctors will assess a patient's cough type, severity, and underlying cause before prescribing benzonatate. It is generally considered when the cough is non-productive (meaning it doesn't bring up phlegm) and is significantly impacting the patient's well-being. Unlike some other cough suppressants, benzonatate works locally in the respiratory tract rather than acting on the brain, which can be a consideration in its selection.
