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.
