Benzonatate
"I developed dry cough for 6 days after having a sore throat. Not being able to sleep at all for almost a week, I finally went to see a doctor. He prescribed 10mg Clarintin and claimed I have post nasal drip, I was skeptical since I didn't have nose issue but took it since I don't want to doubt his professionalism, true enough I was still coughing the following 2 days which made me even more cranky due to the lacked of sleep. Thanks to everyone on this site, I found hope and call the doctor back to ask him for Benzonatate 200mg. After taking for 2 days and three times a day, I was finally sleeping! Remember that this drug works best for dry cough like one of the reviewer said and wet cough might not see result as quickly or as effectively!"
