i was given avalox in 2004 when i was hospitalized for 5 week chronic respiratory infection/ constant asthma wheezing extravaganza, i was seeing things on it and it made me feel much worse. Not full fledged hallucinations but rather seeing things out of the corner of your eye or far away move. Avalox is in the same family (quinolone antibiotics) as levaquin. I never had that kind of a problem on levaquin.
