Fildena 50 contains sildenafil citrate, the same active ingredient found in Viagra, and is commonly used to treat erectile dysfunction. It works by relaxing the blood vessels in the penis, allowing more blood to flow into the area and helping men achieve and maintain an erection during sexual activity. Fildena 50 is typically taken about 30 minutes to an hour before sexual activity, and its effects can last up to four to six hours.
