Benzonatate
"I have had a tremendous hacking cough with walking pneumonia. At my one week follow up, a coughing jag in front of the doctor made him immediately prescribe this drug in the 200mg dosage twice daily. I took it for the first time last night and felt a bit disoriented when it first kicked in. It kept me quiet for most of the night. No cough medicine is going to completely stop your coughing -- and I don't think you'd want it to. Having said that, I've gotten 8 hours of blessed relief and am grateful for this medicine."
