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
           erection such as sickle cell anemia, leukemia or multiple myeloma or
           who have an abnormally shaped penis may not be able to take Viagra ®.
           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. 

Finding the Right Dose for You
           If you arc older than age 65, or have serious liver or kidney problems,
           your doctor may start you at the lowest dose (25 mg) of VIAGRA ®. 

How should I Take VIAGRA ®?
           Take VIAGRA ® about one hour before you plan to have sex. Beginning
            in about 30 minutes and for up to 4 hours, VIAGRA ® can help you get an
            erection when you are sexually excited. You will not get an erection just by
            taking the pill. 

Possible Side Effects of Viagra ®
           Like all medicines, VIAGRA ® can cause some side effects. These effects
           are usually mild and do not last long. Some of these side effects are more
           likely to occur with higher doses. The most common side effects of
           VIAGRA ® are headache, flushing of the face, stuffy nose, urinary tract
           infection, diarrhea upset stomach, and visual changes such as mild and
           temporary changes in blue/green colors or increased sensitivity to light.
