Benzonatate
"Wonderful med! Severe dry cough that got worse. Had a coughing fit that lasted for 6 hours and scared the life out of me. Kaiser prescribed. Took about an hour for coughing to calm down after taking. First night I coughed quite a bit but on the next 100 mg dose cough got better. Do not be discouraged if it does not work right away. Give it a few doses. I also added a humidifier to my bedroom and my coughs were more productive. That coupled with this medicine and I am happy to report after 4 days I am much better. This medicine is my savior. I was up 5 nights straight coughing before I took this."
