What Is Viagra®?
Viagra® is a pill used to treat erectile dysfunction (impotence) in men. It can help many men who have erectile dysfunction get and keep an erection when they become sexually excited (stimulated). You will not get an erection just by taking this medicine. Viagra® helps a man with erectile dysfunction get an erection only when he is sexually excited.

How To Take Viagra®
Take Viagra® about one hour before you plan to have sex. Beginning in about 30 minutes and for up to 4 hours, Viagra® can help you get an erection if you are sexually excited. If you take Viagra® after a high-fat meal (such as a cheeseburger and french fries), the medicine may take a little longer to start working. Viagra® can help you get an erection when you are sexually excited. You will not get an erection just by taking the pill.
How Sex Affects the Body
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 dysfunction if it becomes a frequent problem. During sex, your heart works harder. Therefore sexual activity may not be advisable for people who have heart problems. Before you start any treatment for erectile dysfunction, ask your doctor if your heart is healthy enough to handle the extra strain of having sex. If you have chest pains, dizziness or nausea during sex, stop having sex and immediately tell your doctor you have had this problem.
