Fildena Pill works by improving blood flow to the penis, helping men achieve and maintain an erection during sexual activity. Its active ingredient, Sildenafil Citrate, is a PDE5 inhibitor that relaxes the blood vessels in the penile region. This relaxation allows increased blood flow when sexually stimulated, which results in a firm and lasting erection. Fildena does not cause spontaneous erections—it only works in response to sexual arousal. The effects typically begin within 30 to 60 minutes and can last for up to four hours. It’s a popular and effective treatment option for erectile dysfunction (ED) when used under medical supervision.
