Benzonatate
"I have had allergies for months. The drainage caused me to develop a severe case of bronchitis which triggered my asthma to be worse than ever before. Nothing was working for my cough which was keeping me awake night after night. Sleeping sitting up on the couch for 30 min at a time... Doc at ER gave me 2 Tessalon. Cough stopped almost immediately. First night of sleep I have had in weeks. Thank heavens she wrote me a prescription. Now I am looking forward to my second night cough free. Thank God for small miracles."
