I was prescribed Levaquin (500 mg) for a respiratory infection to be taken once daily for 7 days. I took the first two doses without incident. I remember feeling pretty good before taking my third dose of Levaquin at bedtime, but all that was about to change. I awoke at 2:00 AM from a disturbing nightmare feeling very agitated and depressed. I somehow managed to calm myself down and get a few hours of sleep. When I woke up I was still feeling very anxious and depressed. I knew right away that this had to be the Levaquin, so I immediately threw it in the trash. My depression finally lifted around midday; however, the anxiety stayed with me until evening. I am normally a very calm, healthy, and happy person with no history of depression, and I don't ever recall having any side effects to medication. The most disturbing thing about this experience was how I went from my normal disposition to becoming a completely different person in a matter of hours. I felt very emotionally unstable and kept having random thoughts and images of suicide. I never really felt in danger of doing harm to myself, but the fact that I was even having thoughts and images of this was extremely disturbing. I submitted an incident report through the FDA web site and I encourage others to do the same. Needless to say, I will never take any medication in the future without first investigating its potential side effects. I hope this information will be helpful to others. I felt comfort in this site knowing that others have shared similar experiences. I also wish the best for those of you who still suffer from your side effects from this dangerous medication.
