I was prescribed levaquin 500mg for 7 days for sinus infection. On day 3, I was very dizzy for few minutes where I thought I'd pass out. Next day, I cut down to 250mg but was still getting dizzy to a lesser extent. Day 6, I didn't take it but started getting lower abdominal and lower back pain. So I'll be going to see my doc to see what is going on. Also, knee joint pain. This medication is too difficult to take. I personally think the side effects are greater than the benefits.
