How long after finishing cipro (ciprofloxacin) can I take fluconazole?

7 days. The pathway to remove things (like cipro)from the body may be impaired by some drugs. I think a week should be enough.
Depends. As long as you're not having any lasting side effects from the cipro, (ciprofloxacin) which might mask a reaction to the fluconazole, you can take it as soon as you like.
