Learn Some Viagra Facts
How does Viagra works?
Viagra facts: Viagra increases blood flow to
the penis. When sexually stimulated the arteries in
the penis relax and enlarge. As these arteries expand
the veins taking blood away from the penis are compressed
restricting the blood flow out of the penis, thus causing
an erection. It is if the nerves and blood vessels that
facilitate this process are not working sufficiently
that erectile dysfunction occurs.
Effects from Viagra can be experienced
in as short a time period as 30 minutes and can last
for up to four hours. However, in order to attain an
erection one must be sexually aroused. Viagra is effective
in as many as 80% of cases.
Will Viagra help me?
Viagra facts: The success rate is about 70
percent. Problem candidates usually have conditions
like poorly managed diabetes, blocked arteries, or long-standing
high blood pressure.
Do I have to see a doctor?
Viagra facts: Erectile dysfunction can signal
illnesses such as diabetes, heart disease, and certain
prostate conditions. Your regular physician or a urologist
will get a full medical and sexual history, do a physical
exam, and test your blood and urine.
How quickly does Viagra take
effect?
Viagra facts: It can take as long as an hour,
but some men see results in 20 minutes. Most doctors
start their patients on 50 milligrams of Viagra but
may later alter the dose up to 100 milligrams or down
to 25 milligrams. It may take four or five experiences
using Viagra before you learn the dosage and timing
that are best.
How long does the effect last?
Viagra facts: Four to six hours, or until orgasm.
How often can I take it?
Viagra facts: The approved dosage is no more
than one pill a day. "I know some of my patients,
couples who are high-powered Washington types, who when
they finally get away for a weekend together and want
to have some fun are probably going to take one in the
morning and one at night. That most likely will not
cause a problem," says a Washington urologist.
It might increase the possibility of side effects, which
occur in up to 10 percent of men.
