Vardeforce 20mg is used to treat impotence in men. This is the inability to get or maintain a hard and suitably erect penis for sexual activity due to insufficient blood flow. The active ingredient vardenaphile relaxes the blood vessels of the penis, increases blood flow and causes an erection, which is a natural response to sexual stimulation. The indicated safe dose of Vardeforce 20mg (vardenaphile) within 24 hours is 20mg (1 pill). However, 10mg of Vardeforce (vardenaphile) is recommended as an initial dose. The effective treatment time is 8 hours. This medicine is always taken 30 minutes before the sexual activity and along with a large glass of water.
