Levofloxacin
sinusitis
"Have had a serious sinus infection for 5 years now. It's been getting better, but it flares up every few months. 10 days ago, on the last flare up, the doctor prescribed 10 days of Levaquin. On the first day I experienced strange dreams/nightmares, but I stuck with it. My sinuses haven't been this clear since before the initial infection, even though other antibiotics were tried and failed. The real test will be weeks or months after I'm done with this dose. 

For now, Levaquin is the best thing I've taken for these sinus problems. Within 48 hours, my sinuses felt clear again, and now I'm starting to feel normal - for the first time in 5 years."
