Fildena 50 contains Sildenafil citrate, the active ingredient also found in Viagra. Sildenafil works by relaxing the blood vessels and increasing blood flow to particular areas of the body, most notably the penis, which helps men with erectile dysfunction (ED) achieve and maintain an erection. The standard dose is 50 mg, but doses can be adjusted based on effectiveness and tolerance.
