How long after starting cipro (ciprofloxacin) should a woman start diflucan to prevent a yeast infection?

Yeast infection: The drug Cipro (ciprofloxacin) is a powerful fluoroquinone antibiotic and is in the system days after the last pill is taken. You should ask your doctor if there is a more appropriate antibiotic (based on culture and sensitivity) that can treat your infection without giving you a yeast infection. If you are just extremely sensitive, then talk about probiotics or vaginal suppositories to help maintain your flora.
