pneumonia
"This is a horrible antibiotic, please think twice before you fill this prescription. Very quickly after I took my first dose of Levoquin, my heart started racing. I was literally sweating all day, and could not sleep at all. Gave me horrible anxiety. The side effect lasted for a good 24 hours. When I told my doctor about it, he encouraged me to try it for one more day - and that maybe these side effects were due to a steroid I had taken a day before. I had my doubts but I took one more dose another day. Same exact side effects, more sweating, anxiety, heart palpitations. Couldn't sleep AGAIN. When I tried to take a Xanax to allow myself to sleep the result was really bad and caused even more anxiety. Switched to Augmentin."
