Uses

What is Vardenafil used for?

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

Vardenafil is used to treat erectile dysfunction (impotence).

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

How should I take Vardenafil?

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

Vardenafil can be taken with or without food.

Vardenafil is usually taken only when needed, about 60 minutes before sexual activity. The medicine can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Follow your doctor’s instructions.

To take the orally disintegrating tablet (Staxyn):

  • Keep the tablet in its blister pack until you are ready to take it. Open the package and peel back the foil from the tablet blister. Do not push a tablet through the foil or you may damage the tablet.
  • Using dry hands, remove the tablet and place it in your mouth. It will begin to dissolve right away.
  • Do not swallow the tablet whole. Allow it to dissolve in your mouth without chewing.
  • Swallow several times as the tablet dissolves. Do not take Staxyn with liquid.
  • Do not take vardenafil more than once a day. Allow 24 hours to pass between doses.
  • 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.

How do I store Vardenafil?

Vardenafil is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store Vardenafil in the bathroom or the freezer. There may be different brands of Vardenafil that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.

You should not flush Vardenafil down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.

Precautions & warnings

What should I know before using Vardenafil?

Before using this drug, tell your doctor if:

  • You are pregnant or breastfeeding. This is because, while you are expecting or feeding a baby, you should only take medicines on the recommendation of a doctor.
  • You are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
  • You have allergy with any of active or inactive ingredients of Vardenafil or other medications.
  • You have any other illnesses, disorders, or medical conditions.

Taking vardenafil with certain other medicines can cause a sudden and serious decrease in blood pressure. Do not take vardenafil if you also take riociguat (Adempas), or if you take a nitrate drug for chest pain or heart problems. Nitrates include nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite (“poppers”).

Vardenafil 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 Viagra or other drugs similar to vardenafil. Most of these people also had certain pre-existing eye problems or risk factors for blood vessel disorders (such as heart disease, diabetes, high blood pressure, high cholesterol, coronary artery disease, smoking, or being over 50 years old). It is not clear whether vardenafil is the actual cause of vision loss.

Although vardenafil is not for use in women, it is not known whether this medicine passes into breast milk or if it could harm a nursing baby.

Staxyn may contain phenylalanine. Talk to your doctor before using this form of vardenafil if you have phenylketonuria (PKU).
