How Viagra Works

 

When a man is sexually excited, the penis rapidly fills with more blood than usual. The penis then expands and hardens. This is called an erection. After the man is done having sex, this extra blood flows out of the penis back into the body. The erection goes away. If an erection lasts for a long time (more than 6 hours), it can permanently damage your penis. You should call a doctor immediately if you ever have a prolonged erection that lasts more than 4 hours. Some conditions and medicines interfere with this natural erection process. The penis cannot fill with enough blood. The man cannot have an erection. This is called erectile disfunction if it becomes a frequent problem.

VIAGRA ® enables many men with erectile disfunction to respond to sexual stimulation. When a man is sexually excited, VIAGRA ® helps the penis fill with enough blood to cause an erection. After sex is over, the erection goes away.
