Häufig gestellte Fragen
Is Ciprofloxacin better than Vardenafil? ▾
Ciprofloxacin and Vardenafil are not "better or worse" — they treat different things. The sensible question is which fits your specific need.

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