What Are the Risks of Benzonatate?
A significant risk associated with benzonatate is accidental ingestion by children, which can lead to serious toxicity, including seizures, cardiac arrest, and death [2]. It is crucial to store benzonatate safely away from children and to ensure that capsules are swallowed whole, not chewed or sucked, as this can cause local numbness in the mouth and throat [1][2].
When Does Benzonatate Patent Protection End?
