History
This IS ONLY a summary. It contains important information
about
VIAGRA ®. It is not meant to take the place of your doctor's instructions.
Please read this information carefully before you start taking VIAGRA
®. If
you do not understand any of this information Ask your doctor or
pharmacist.
This medication can help many men when it is used as directed by a
doctor. However, VIAGRA ® is not for everyone. It is intended
for use by
men who have erectile dysfunction. Viagra ® must never be
used by men
who are taking medicines that contain nitrates (nitroglycerin) of any
kind.
(You should not take viagra ® even if you only take nitroglycerin
medication occassionally)
What
Is VIAGRA ®?
VIAGRA ®is a pill used to treat erectile dysfunction (impotence)
in men. It
can help many men who have erectile dysfunction get and keep an
erection
when they become sexually excited (stimulated). You will not
get an
erection just by taking this medication. VIAGRA ® helps a man with
erectile dysfunction get an erection only when he is sexually excited.
How
Sex Affects the Body
When a man is sexually excited, the penis rapidly fills with more
blood than
usual. The penis then expands and hardens. This is called an erection.
After
the man is done having sex, this extra blood flows out of the penis
back
into the body. The erection goes away. If an erection lasts for a long
time
(more than 4 hours) you should call a doctor.
Some conditions and medicines interfere with this natural erection
process
and a man cannot have an erection. If it becomes a frequent problem,
this
is called erectile dysfunction.
During sex, your heart works harder. Before you start any treatment
for
erectile dysfunction, ask your doctor if you are healthy enough to
handle
the extra strain of having sex.
How
VIAGRA ® Works
In many men with erectile dysfunction, VIAGRA ® helps the body's
natural
erection process. When a man is sexually excited, the penis will fill
with
enough blood to cause an erection. After sex is over, the erection
goes away.
VIAGRA
® Is Not for Everyone
VIAGRA ® is only for patients with erectile dysfunction. VIAGRA
®is not
for newborns, children, or women. Do not let anyone else take your
VIAGRA ®. VIAGRA ® must be used only under a doctors supervision.
VIAGRA ® must never be used by men who are taking any medicines
that
contain nitrates. Nitrates are found in many prescription medicines
that are
used to treat angina (chest pain due to heart disease) such as:
nitroglycerin (sprays, ointments, skin patches or pastes, and tablets
that are
swallowed or dissolved in the mouth) isosorbide mononitrate and
isosorbide dinitrate (tablets that are swallowed, chewed, or dissolved
in
the mouth) Nitrates are also found in illicit drugs such as amyl nitrate
or
nitrite ("poppers"). If you are not sure if any of your medicines contain
nitrates, or if you do not understand what nitrates are, ask your doctor
or
pharmacist. If you take VIAGRA ® with any nitrate medicine or illicit
drug
containing nitrates, your blood pressure could suddenly drop to an
unsafe
level. You could get dizzy, faint, or even have a heart attack or stroke.
What
VIAGRA ® Does Not Do
* VIAGRA ® does not cure erectile dysfunction. It is a treatment
for
erectile dysfunction.
* VIAGRA ® does not protect you or your partner from getting sexually
transmitted diseases, including HIV-the virus that causes AIDS.
* VIAGRA ® is not a hormone or an aphrodisiac.
General
Precautions with Viagra ®:
You should have a complete medical evaluation to determine the
cause of your impotence before taking Viagra ®.
Men who have medical conditions that may cause a sustained

There are several medications that are known to interact with Viagra
®, so be sure to tell your doctor about all medications you are
taking
including those you can get without a prescription.
Viagra ®has not been studied with other treatments for impotence,
so use in combination with other treatments is not recommended.

get an
