Fildena 100 is a medication used to treat erectile dysfunction (ED) in men. The active ingredient in Fildena 100 mg is sildenafil citrate, which is also the active ingredient in the brand-name medication Viagra.

Fildena 100 and Viagra are very similar medications, as they both contain sildenafil citrate and work by increasing blood flow to the penis, resulting in an erection during sexual stimulation. Fildena 100 is a generic version of Viagra and is manufactured by a different company, but it is equivalent in terms of effectiveness and safety.
