Usually in 2-3 days
Avelox has a half-life of about 12 hours (taken orally, 15hrs in IV form)--this means in 12 hours, 1/2 of what you took into your body is gone.
In another 12hours, 1/4 left, at 36hours, 1/8 isl left etc..So for for the typical course of about 10 days therapy, most of the Cipro (ciprofloxacin
) is out of your system in about 2-3 days following your last dose--very cool biochemistry. Have fun learning. Good luck.
