77. Which auxiliary label should be affixed to a prescription vial containing benzonatate?

Answer: C

Explanation:

Chewable tablets of benzonatate should not be chewed.

Benzonatate should have a label indicating "Do Not Chew" because it is designed to be swallowed whole. Chewing the capsule can lead to serious side effects and reduce the medication's effectiveness.

A) For Topical Use Only

This label is incorrect because benzonatate is not a topical medication; it is an oral medication used to suppress cough. Therefore, labeling it for topical use would mislead users regarding its intended application.

B) Refrigerate

This option is incorrect because benzonatate does not require refrigeration. Storing it at room temperature is appropriate, and refrigeration could potentially affect the integrity of the medication.

C) Do Not Chew

This label is correct as benzonatate capsules must be swallowed whole to prevent the risk of local anesthesia effects in the mouth and throat, which can occur if chewed or dissolved. This warning is critical for safe usage.

D) For Rectal Use Only

This label is incorrect because benzonatate is not indicated for rectal use. Such a label would be misleading and could cause harm if individuals were to use the medication inappropriately.

Conclusion

The correct label "Do Not Chew" is essential for ensuring that benzonatate is used safely and effectively. All other options either misrepresent the medication's use or are not applicable, highlighting the importance of proper labeling in medication safety.
