What is Viagra?
Viagra is an oral impotency medication made by Pfizer and introduced to the
pharmaceutical
market in 1998. Viagra allows men to achieve stronger erections during sexual
stimulation.
How does Viagra work?
Viagra opens blood vessels in the body, which allows for greater blood
circulation to the penis during sexual stimulation. As the arteries of the penis
harden and expand, blood flow out of the penis is restricted, thus causing an
erection. After sexual activity, blood is allowed to flow out from the penis and
the erection subsides.
What is the success rate of Viagra?
In past studies, Viagra has shown to improve men's ability to achieve erections
in 80% of men.
What does Viagra not
do?
 | Viagra does not cure erectile dysfunction. It is only a
treatment for the symptoms of erectile dysfunction. |
| Viagra does not protect you or your partner from getting
sexually transmitted diseases including HIV virus that causes AIDS.
|
| Viagra is not a hormone or an aphrodisiac. |
When should
Viagra be taken?
Viagra should be taken 30-60 minutes before sexual activity is expected. Viagra
should be taken a maximum of once per 24-hour period.
Can women take Viagra?
At this time, Pfizer is conducting testing for Viagra on women in Europe. There
is no concrete evidence that Viagra is effective for women. Until such evidence
exists from Pfizer or the FDA, it is recommended that women do not take Viagra.
Who should not take Viagra?
Men with hypertension (high blood pressure) should not take Viagra. Men taking
nitrate-based medications such as nitroglycerine or nitrate-based illicit drugs
such as amyl "poppers" should not take Viagra, as it could lower blood pressure
to a dangerous level. Children should not take Viagra.
