Precautions & warnings

What should I know before using Levitra® (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 Levitra® or other medications.
  • You have any other illnesses, disorders, or medical conditions.

You should not use Levitra® if you are allergic to vardenafil.

Taking Levitra® 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.

To make sure Levitra® is safe for you, tell your doctor if you have:

  • Heart disease, heart rhythm problems
  • A recent history (in the past 6 months) of a heart attack, stroke, or congestive heart failure
  • A personal or family history of Long QT syndrome
  • High or low blood pressure
  • Seizures
  • Liver disease, kidney disease (or if you are on dialysis)
  • A blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia
  • A bleeding disorder such as hemophilia
  • A stomach ulcer
  • Hearing or vision problems, history of vision loss
  • An eye disorder such as retinitis pigmentosa (an inherited condition of the eye)
  • A physical deformity of the penis (such as Peyronie’s disease)
  • If you have been told you should not have sexual intercourse for health reasons

Levitra® 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.

FDA pregnancy risk category reference below:

  • A=No risk
