cough
"I have occasional asthma and always get stubborn bronchitis every time I get a cold. My lungs get easily irritated and spasm, and I can have intense coughing fits that result in gagging and vomiting. It's a vicious circle since the irritation and spasms cause coughing resulting in more irritation, etc. My physician prescribed Benzonatate for this and it has been wonderfully effective. It works better for me the Codeine cough syrup. The Codeine seems to calm things down, but the benzonatate puts a big stop on the irritated dry cough. My lungs can calm down and heal now. So glad this drug exists!"
