Cough
"I was prescribed benzonatate today for the third time in the last few years. I have a wicked sinus infection and hacking cough. Every time I have been prescribed benzonatate, I have had a good attitude, &quot;Maybe this time it will work.&quot; Every time I have used it, I have felt like I was given a placebo by mistake. No side effects at all, but it has never worked for me. Not working today either.  Still hacking."
