Benzonatate
"I was diagnosed with walking pneumonia and maybe Bronchitis. After 3 weeks of feeling really bad, with all flu symptoms. Coughing, sore throat and feeling crummy, I finally went to the Dr. She prescribed Benzonatate 100mg 3x a day as needed.  Plus Amoxcillan. Took 3 doses yesterday of the Benzonatate 2 today before deciding that it was making me worse.  After reading reviews, I see that I'm not the only one experiencing theses side effects.  I feel like I'm coughing up a Lung, (I'm sure my neighbors hate me) fever, night sweats, headache so bad feels like my head will explode. Depressed...decided not to take anymore and still have side effects day 3. Calling Dr. In the morning.  Correction in a few hours.  It's 5:30 a.m. no sleep. Do not recommend."
