About Viagra

VIAGRA is a prescription drug used to treat erection difficulties, such as erectile dysfunction (ED). Since it first became available in 1998, the prescription drug VIAGRA has helped about 16 million men around the world improve their sex lives. Amazingly, 9 tablets are dispensed every second worldwide. And no other therapy or prescription drug for erectile dysfunction has been studied as much or has the same amount of real-world experience as VIAGRA since its launch. It's no wonder more than 600,000 doctors have chosen the prescription drug VIAGRA for their patients with ED.

Fact is, when taken correctly, VIAGRA works for most men. Studies show that it works for up to 4 out of 5 men (versus 1 out of 4 on sugar pill). VIAGRA improves erections in most men no matter how long they have had ED, what caused it, how often they have it, or how old they are. And VIAGRA has been proven to work in clinical studies of thousands of men.

VIAGRA is a prescription drug that works by increasing blood flow to the penis. It is not a hormone or an aphrodisiac. Once you take it, VIAGRA can work in as quickly as 30 minutes. VIAGRA works for 4 hours so you can set your own pace. And, in most patients, VIAGRA can be taken as often as once a day.

How safe is VIAGRA?

You may have some questions about the safety of VIAGRA. This is normal for any person taking any drug, especially when it has to do with something as important as your sexual health. One thing you can feel good about is that VIAGRA has been tested in more than 130 controlled studies (completed and ongoing) including over 13,000 men. Through these studies and its real-world experience, VIAGRA has been shown to have a strong safety profile. VIAGRA has helped about 16 million men around the world improve their sex lives. VIAGRA is the #1 prescribed medicine for ED in the US.

You may be taking medicine for high blood pressure. If so, you should also be glad to know that, of the nearly 10 million men in the US who have taken VIAGRA, more than 1 million of them have also taken medicines for high blood pressure.

How does VIAGRA work?

ED is often a physical problem. VIAGRA is a medicine that treats this problem by increasing blood flow where you need it. With VIAGRA, you must be sexually excited to get an erection. If you take VIAGRA and are not sexually stimulated, nothing will happen. You won't get an erection just by taking the pill. VIAGRA is not an aphrodisiac or a hormone. It's a medicine that treats the physical problem of ED. Here's what usually happens when a man is sexually excited:

1. The arteries in the penis relax and widen (this allows more blood to flow into the penis).
2. The increased blood flow causes the penis to become hard and erect.
3. The veins that normally carry blood away from the penis get compressed (this restricts the blood flow out of the penis).
4. More blood begins flowing in and less flows out, making the penis larger; this causes an erection.

For most men, the nerves or blood vessels that play a part in this process work properly. For other men, this may not be true. In these cases, the man may not be able to get an erection. VIAGRA works by increasing blood flow to the penis. This way, when a man is sexually excited, he can get and keep an erection.

How well does VIAGRA work?

VIAGRA works for most men who take it. In studies, more than 4 out of every 5 men taking VIAGRA had better erections versus 1 out of 4 on sugar pill. VIAGRA works in most men no matter how long they have had ED, what caused it, or how old they are. And VIAGRA has been shown to work time and again in studies of thousands of patients. In those studies, patients had ED that ranged from mild to severe.

And VIAGRA works fast. In fact, VIAGRA works in as quickly as 30 minutes. Then, you have at least 4 hours to have a romantic experience at your own pace. In most patients, VIAGRA can be taken once a day as needed.
