I was prescribed a 7 day dosage (500mg/2x daily) of cipro for an infection. On the last day I developed a rash breakout about the size of a half dollar near my armpits. I thought it might be from some fruit that I had eaten, perhaps a food allergy, but it has been 5 days since I have eaten any fruit, and the rash persists. Could this be a side effect of the cipro, and, if so. any advice of how to get it out of my system?
