Questions fréquentes
Is Finasteride better than Ciprofloxacin? ▾
Finasteride and Ciprofloxacin are not "better or worse" — they treat different things. The sensible question is which fits your specific need.
Can Finasteride and Ciprofloxacin be combined? ▾
Whether they can be combined depends on the indications and the interaction profile of each. If both are in a single prescription, the prescriber has weighed it; in self-medication they should never be combined.

No — they belong to different classes and have distinct side-effect profiles. Each has its own prescribing information.
