Levaquin 500mg prescribed for bronchitis for 10 days. Doctor had to stop on day 7 because of migraine aura told to be low blood sugar. This was in December, 2006. After stopping there has been difficulty walking, with severe pain in legs. Also migraine auras return and are still present three months later. These symptoms were not present in December. This is a poison. Why this drug was given I do not know. There are plenty of other antibiotics which I have taken which did not cause symptoms once stopped.
There was one other that was horrible, Ketek, which has now been stopped because of liver problems.
Would not take Levaquin again.
