Benzonatate: Brands, Price & Uses in Bangladesh
Benzonatate is FDA-approved for the symptomatic relief of cough in adults and children older than 10 years of age.
About Benzonatate
Indications of Benzonatate
Benzonatate is FDA-approved for the symptomatic relief of cough in adults and children older than 10 years of age.
- Established/FDA-approved use: Short-term relief of non-productive cough due to minor upper respiratory tract infections (e.g., the common cold), and cough associated with bronchitis, pneumonia, or other conditions where cough suppression is clinically appropriate.
- Off-label use (not FDA-approved): Benzonatate is sometimes used off-label to suppress the gag reflex before upper endoscopy, transesophageal echocardiography, or dental procedures; evidence supporting this use is limited and it should be used this way only at a physician's discretion.
Benzonatate relieves only the symptom of cough; it does not treat the underlying cause. A cough that is persistent, severe, worsening, or accompanied by fever, rash, or difficulty breathing should be evaluated by a physician.
