I have no personal experience of Levaquin or the other quinolone antibiotics (Cipro etc.)
A very dear friend was prescribed Ciprofloxacin during the summer of 2004. I am sure that was the reason for his sudden confusion among other things.
His suffering made me look for information on the Internet and I read a lot of books by Peter R. Breggin and Stephen Fried.
Today I just received another one - Medicine Madness ( Peter R. Breggin) and I am happy to say that he has also included a chapter about ordinary prescribed drugs that can cause psychiatric symptoms.
He, for instance, writes about "Antibiotic Madness".
It`s about this very group of antibiotics.
Here are some lines from his text:
"Hardly anyone thinks of antibiotics as potentially dangerous psychoactive drugs but many of them are".
"Levaquin is a member of the quinolones family of antibiotics, a group that is known to cause severe emotional reactions".
The best thing you can do for yourself and the people around you is to inform your self!
