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.

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;

  • swelling in your hands, ankles, or feet;
  • shortness of breath;

This is not a complete list of side effects and others may occur.

Important Information 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.

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.

How To 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.

If You Miss A Dose (Revatio, Viagra)

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

If you miss a dose of Revatio, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What To 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.

Drugs That 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.
