Cough
"I was prescribed this medication at the ER, after a coughing fit so severe I almost passed out. I took my narcotic cough syrup before bed. I woke up about 6 hours later coughing, so I took the Tessalon Perles. My coughing stopped, but I got every side effect. My head was pounding so bad I couldn&#039;t sit or stand for more than a few minutes. I was very disappointed, because I needed something to get me through the day. This medication worked great on my cough, but I felt worse in every other perspective."
