What is Viagra?
VIAGRA is a medicine used to treat erection difficulties, such as erectile dysfunction (ED). Since it first became available in 1998, VIAGRA has helped more than 16 million men around the world improve their sex lives. Amazingly, 9 tablets are dispensed every second worldwide. And no other therapy for ED 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 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 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 at least 4 hours so you can set your own pace. And, in most patients, VIAGRA can be taken as often as once a day.
