Fildena is a brand of sildenafil, a PDE5 inhibitor used to treat erectile dysfunction (ED). Product information identifies Fildena products as containing sildenafil, with strengths such as 100 mg and other formulations available. Sildenafil works by increasing blood flow to the penis during sexual stimulation, helping you achieve and maintain an erection. It does not directly increase sexual desire and does not produce an erection without sexual stimulation.
