A generic form of sildenafil is called Fildena Pills. When it came to treating erectile dysfunction, it was the first medicine authorized for use. Sildenafil citrate is the active ingredient in Fildena. Keep in mind that if a man is not sexually stimulated, this medicine will not work. Keep these tablets out of children’s reach and at room temperature, away from sources of heat and moisture. When using Fildena, refrain from consuming grapefruit or grapefruit juice.
