I had a bad bladder infection last year and was prescribed levoquin. Unfortunately, my breathing was also being affected by mg at the time and I did't do the research before I took the levoquin. 2 days later I collapsed at work (unable to breathe in) and went by ambulance to ER and ended up in ICU for 4 days until breathing stabilized. Fortunately, IVIG did the trick and I didn't have to be intubated.

I now have levoquin on my list of allergies and will never take it again.

But as everyone has said, everyone is different. Just be aware, it can affect your breathing.
