Precautions
Drug information provided by: Merative, Micromedex®
It is important that you tell all of your doctors that you take vardenafil. If you need emergency medical care for a heart problem, it is important that your doctor knows when you last took vardenafil.
Do not use this medicine if you are also using a nitrate medicine for angina or high blood pressure. Some examples of nitrate medicines include nitroglycerin, isosorbide, Imdur®, Nitro-Bid®, Nitro-Dur®, Nitrol® ointment, Nitrolingual® spray, Nitrostat®, and Transderm Nitro®. Some illegal ("street") drugs called "poppers" also contain nitrates such as amyl nitrate and butyl nitrate. Do not use this medicine if you also use riociguat (Adempas®).
If you experience a prolonged or painful erection for 4 hours or more, contact your doctor right away. This condition may require prompt medical treatment to prevent serious and permanent damage to your penis.
If you have a sudden loss of vision in one or both eyes, contact your doctor right away.
Check with your doctor right away if you have a sudden decrease in hearing or loss of hearing with dizziness or ringing in the ears.
If you already use medicine for high blood pressure (hypertension), vardenafil could make your blood pressure go too low. Call your doctor right away if you have blurred vision, confusion, dizziness, faintness, or lightheadedness when getting up suddenly from a lying or sitting position, sweating, or unusual tiredness or weakness.
This medicine does not protect you against sexually transmitted diseases (including HIV or AIDS). Use protective measures and ask your doctor if you have any questions about this.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
