As a result men are able to get the hard and strong erection and sustain it for the ample period of time during the sexual intercourse. Sildenafil allows the men to get the erection for about 4 to 6 hours after taking the dosage. The dosage of the Sildenafil should be taken 45 minutes to 1 hour before the sexual activity to enjoy the maximum benefits.
