What is sildenafil (Revatio, Viagra)?

   Sildenafil relaxes muscles of the blood vessels and increases blood
   flow to particular areas of the body.

   Sildenafil under the name Viagra is used to treat erectile
   dysfunction (impotence) in men. Another brand of sildenafil is
   Revatio, which is used to treat pulmonary arterial hypertension and
   improve exercise capacity in men and women.

   Do not take Viagra while also taking Revatio, unless your doctor tells
   you to.

   Sildenafil may also be used for purposes not listed in this medication
   guide.

What are the possible side effects of oral sildenafil (Revatio, Viagra)?

   Get emergency medical help if you have signs of an allergic reaction:
   hives; difficulty breathing; swelling of your face, lips, tongue, or
   throat.

   Stop taking sildenafil and get emergency medical help if you have:
     * heart attack symptoms--chest pain or pressure, pain spreading to
       your jaw or shoulder, nausea, sweating;
     * vision changes or sudden vision loss; or
     * erection is painful or lasts longer than 4 hours (prolonged
       erection can damage the penis).

   Call your doctor at once if you have:
     * ringing in your ears, or sudden hearing loss;
     * irregular heartbeat;
     * swelling in your hands, ankles, or feet;
     * shortness of breath;
     * seizure (convulsions); or
     * a light-headed feeling, like you might pass out.

   Common side effects may include:
     * flushing (warmth, redness, or tingly feeling);
     * headache, dizziness;
     * abnormal vision (blurred vision, changes in color vision)
     * runny or stuffy nose, nosebleeds;
     * sleep problems (insomnia);
     * muscle pain, back pain; or
     * upset stomach.

   This is not a complete list of side effects and others may occur. Call
   your doctor for medical advice about side effects. You may report side
   effects to FDA at 1-800-FDA-1088.

What is the most important information I should know about oral sildenafil
(Revatio, Viagra)?

   Some medicines can cause unwanted or dangerous effects when used with
   sildenafil. Tell your doctor about all your current medicines,
   especially riociguat (Adempas).

   Do not take sildenafil if you are also using a nitrate drug for chest
   pain or heart problems, including nitroglycerin, isosorbide dinitrate,
   isosorbide mononitrate, and some recreational drugs such as
   "poppers". Taking sildenafil with a nitrate medicine can cause a sudden
   and serious decrease in blood pressure.

   Contact your doctor or seek emergency medical attention if your
   erection is painful or lasts longer than 4 hours. A prolonged erection
   (priapism) can damage the penis.

   Stop using sildenafil and get emergency medical help if you have sudden
   vision loss.

What should I discuss with my healthcare provider before taking oral
sildenafil (Revatio, Viagra)?

   You should not use sildenafil if you are allergic to it, or:
     * if you take other medicines to treat pulmonary arterial
       hypertension, such as riociguat (Adempas).

   Do not take sildenafil if you are also using a nitrate drug for chest
   pain or heart problems. This includes nitroglycerin, isosorbide
   dinitrate, and isosorbide mononitrate. Nitrates are also found in some
   recreational drugs such as amyl nitrate or nitrite ("poppers"). Taking
   sildenafil with a nitrate medicine can cause a sudden and serious
   decrease in blood pressure.

   To make sure sildenafil is safe for you, tell your doctor if you have
   ever had:
     * heart disease or heart rhythm problems, coronary artery
       disease;
     * heart attack, stroke, or congestive heart failure;
     * high or low blood pressure;
     * liver or kidney disease;
     * a blood cell disorder such as sickle cell anemia, multiple
       myeloma, or leukemia;
     * a bleeding disorder such as hemophilia;
     * a stomach ulcer;
     * retinitis pigmentosa (an inherited condition of the eye);
     * a physical deformity of the penis (such as Peyronie's disease);
       or
     * if you have been told you should not have sexual intercourse for
       health reasons.

   Sildenafil can decrease blood flow to the optic nerve of the eye,
   causing sudden vision loss. This has occurred in a small number of
   people taking sildenafil, most of whom also had heart disease,
   diabetes, high blood pressure, high cholesterol, or certain
   pre-existing eye problems, and in those who smoked or were over 50
   years old. It is not clear whether sildenafil is the actual cause of
   vision loss.

   This medicine is not expected to harm an unborn baby. Tell your doctor
   if you are pregnant or plan to become pregnant.

   It is not known whether sildenafil passes into breast milk or if it
   could harm a nursing baby. Tell your doctor if you are breast-feeding a
   baby.

   Do not give this medication to anyone under 18 years old without
   medical advice.

How should I take oral sildenafil (Revatio, Viagra)?

   Follow all directions on your prescription label. Do not take this
   medicine in larger or smaller amounts or for longer than recommended.

   Revatio is usually taken three times each day, about 4 to 6 hours
   apart.

   Viagra is usually taken only when needed, 30 minutes to 1 hour before
   sexual activity. You may take it up to 4 hours before sexual activity.
   Do not take Viagra more than once per day.

   Shake the oral suspension (liquid) well just before you measure a dose.
   Measure liquid medicine with the dosing syringe provided, or with a
   special dose-measuring spoon or medicine cup. If you do not have a
   dose-measuring device, ask your pharmacist for one.

   Viagra can help you have an erection when sexual stimulation occurs. An
   erection will not occur just by taking a pill. Follow your doctor's
   instructions.

   During sexual activity, if you become dizzy or nauseated, or have pain,
   numbness, or tingling in your chest, arms, neck, or jaw, stop and call
   your doctor right away. You could be having a serious side effect of
   sildenafil.

   Store at room temperature away from moisture and heat.

What happens if I miss a dose (Revatio, Viagra)?

   Since Viagra is used as needed, you are not likely to miss a dose.

What should I avoid while taking oral sildenafil (Revatio, Viagra)?

   Drinking alcohol with this medicine can cause side effects.

   Grapefruit and grapefruit juice may interact with sildenafil and
   lead to unwanted side effects. Avoid the use of grapefruit products
   while taking sildenafil.

   Avoid using any other medicines to treat impotence, such as alprostadil
   or yohimbine, without first talking to your doctor.

What other drugs will affect oral sildenafil (Revatio, Viagra)?

   Do not take sildenafil with similar medications such as avanafil
   (Stendra), tadalafil (Cialis) or vardenafil
   (Levitra). Tell your doctor about all other medications you use for
   erectile dysfunction.

   Tell your doctor about all your current medicines and any you start or
   stop using, especially:
     * drugs to treat high blood pressure or a prostate disorder;
     * an antibiotic--clarithromycin, erythromycin, or
       telithromycin;
     * antifungal medicine--ketoconazole or itraconazole; or
     * medicine to treat HIV/AIDS--atazanavir, indinavir, ritonavir, or
       saquinavir.

   This list is not complete. Other drugs may interact with sildenafil,
   including prescription and over-the-counter medicines, vitamins, and
   herbal products. Not all possible interactions are listed in this
   medication guide.
