Benzonatate is a cough suppresent man.. but nah u can't get high off of it to the best of my knowledge. If you were prescribed benzonatate, you may be able to score some liquid hydrocodone tho haha.
Benzonatate, is the active ingredient... it is a non-narcotic cough suppresent. When I got Benzonatate prescribed they gave me a 120 serving bottle of Hydromet (hydrocodone syrup, NO tylenol woohoo hahaha).
