I took Levaquin as a third antibiotic for the treatment of a bad case of bronchitis that went into asthma and have had a chronic cough. This started one month ago. I first took Zithromax, then Augmentin. The Levaquin was a third antibiotic. The first day I felt I felt dizzy and lightheaded. the first night I had total insomnia and could not sleep. I woke up feeling very nauseated. The second day I felt even more dizzy than the day before. The second night I broke out into hives and itching on my feet. I took Benadryl and discontinued the antiobiotic.
