I had one single does of Ciprofloxacin and awoke in the middle of the night with a burning clear sticky liquid dripping from my nose. and I was seeing electric blue fish scale pattern everywhere, I knew this was an hallucination so I thought I was having a flash back from the previous decade when I last did LSD.
But I told the nurse and the nurse called the doctor who immediately stopped the use of Ciprofloxacin and it went away after a few hours.
Seems that these were symptoms of an allergic reaction to Ciprofloxacin.
