Benzonatate is used for cough. It may cause drowsiness in some people. It should never be chewed and should always be swallowed whole.

I assume the other drug your are asking about is clonazepam (Klonopin). It is a benzodiazepine. It, too, causes drowsiness.

Other than the increased drowsiness from taking both of these agents together, there are no clinically significant interactions.
