What is Benzonatate?
Benzonatate is a non-narcotic antitussive medication used to relieve cough symptoms. It works by anesthetizing stretch receptors in the lungs and respiratory passages, which helps to reduce the cough reflex. [1]
How does Benzonatate work?
Benzonatate acts peripherally, meaning it targets the nerves involved in the cough reflex in the lungs and pleura, rather than acting on the cough center in the brain like some other cough suppressants. By numbing these sensory nerve endings, it prevents the signals that trigger coughing from reaching the brain. [1]
When can I expect to see generic versions of Benzonatate?
The availability of generic versions of benzonatate is influenced by patent expirations and market exclusivity periods. Information on specific patent timelines and potential generic entry dates can be found on resources like DrugPatentWatch.com. [2]
Are there different strengths of Benzonatate available?
Benzonatate is typically available in capsules of 100 mg and 200 mg. [1]
What are the side effects of Benzonatate?
Common side effects can include headache, dizziness, drowsiness, nausea, and rash. Serious but rare side effects may involve hallucinations, chest pain, or difficulty breathing. It is crucial not to chew or dissolve the capsules in the mouth, as this can lead to numbing of the mouth and throat, posing a risk of choking. [1]
What is the typical dosage for Benzonatate?
The usual adult dosage is one 100 mg or 200 mg capsule three times a day. It should be swallowed whole. [1]
How does Benzonatate compare to other cough suppressants?
Unlike opioid-based cough suppressants such as codeine, benzonatate is non-narcotic and does not typically cause respiratory depression or addiction. Its peripheral action is also distinct from central-acting cough suppressants. [1]
What happens if I accidentally chew or dissolve a Benzonatate capsule?
Chewing or dissolving benzonatate capsules in the mouth can cause temporary local anesthesia of the oral and pharyngeal mucosa. This can lead to a loss of sensation and potentially a choking hazard. If this occurs, immediate medical attention may be needed. [1]
