I was prescribed Levaquin after taking the prescribed dosage of Zithromax, and my symptons did not clear up. I took the Levaquin for 3 days, I could not sleep well at night, I had bad dreams, my joints ache. On top of not being able to sleep, I was restless, and I just felt out-of sorts. I did not read the side effects informational sheet they gave me with the prescription. I guess I was feeling to bad. I am going back to the Dr. tomorrow, I stopped taking it.
