I was prescribed Ciprofloxacin for traveler's diarrhea when I was traveling internationally for an extended period of time. I knew it was some hardcore stuff, so I didn't use it until it was a last resort. A single dose, and within 40 minutes I was experiencing neurological effects. I called a nurse-on-call and was told to discontinue. No permanent effects I know of, but it basically gave me temporary dementia. Definitely a medication that should come with stronger warnings. I know it's the only valid treatment for anthrax infections, but for general use it should not be prescribed.
