Levitra increases venous congestion in that area and helps a man get and keep an erection during sexual intercourse. By itself, Levitra does not cause an erection - there must also be physical stimulation of the penis to achieve an erection. Levitra is only for use in men. Women should never take it, especially if they are pregnant or breastfeeding.
Vardenafil has been licensed to treat erectile dysfunction. Erectile dysfunction (ED), also known as impotence, can be a total inability to achieve an erection, an inconsistent ability to do so, or a tendency to sustain only brief erections. Essentially, erectile dysfunction is the repeated inability to get or keep an erection firm enough for sexual intercourse.
Vardenafil (INN) is a PDE5 inhibitor used for treating erectile dysfunction that is sold under the trade names Levitra (Bayer AG, GSK, and SP), Staxyn in India, and Vivanza in Italy.
Beyond its indications for erectile dysfunction, vardenafil may be effective in the treatment of premature ejaculation, where it may significantly increase the time from penetration to ejaculation.
Vardenafil (INN) is a PDE5 inhibitor used for treating erectile dysfunction. Vardenafil's indications and contra-indications are the same as with other PDE5 inhibitors; it is closely related in function to sildenafil citrate () and tadalafil (Cialis). The difference between the vardenafil molecule and sildenafil citrate is a nitrogen atom's position and the change of sildenafil's piperazine ring methyl group to an ethyl group. Tadalafil is structurally different from both sildenafil and vardenafil. Vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's.
Before using vardenafil
Some medical conditions may interact with vardenafil. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
if you are pregnant, planning to become pregnant, or are breast-feeding
if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
if you have allergies to medicines, foods, or other substances
if you have a deformed penis (eg, cavernosal fibrosis, Peyronie disease), blood cell problems (eg, leukemia, multiple myeloma, sickle cell anemia), or any other condition that may increase the risk of a prolonged erection (priapism)
if you have a history of a prolonged (more than 4 hours) or painful erection (priapism)
if you have a history of certain eye problems (eg, macular degeneration, optic neuropathy, retinitis pigmentosa, sudden vision loss) or hearing problems (eg, ringing in the ears, decreased hearing, hearing loss)
if you have a history of liver or kidney problems, dialysis, high or low blood pressure, ulcers, seizures, lung problems (eg, pulmonary veno-occlusive disease), bleeding problems, blood vessel problems, or heart problems (eg, angina, aortic stenosis, heart failure)
if you have a history of heart attack, stroke, a certain type of irregular heartbeat (long QT syndrome), or a family history of long QT syndrome
Why Is this Medication Prescribed?
Vardenafil is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men. Vardenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. It works by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Vardenafil does not cure erectile dysfunction or increase sexual desire.
Vardenafil comes as a tablet and a rapidly disintegrating (dissolves in the mouth and is swallowed without water) tablet to take by mouth. It is usually taken as needed, with or without food, 60 minutes before sexual activity. Vardenafil usually should not be taken more often than once every 24 hours.
For most individuals, the recommended dose of vardenafil regular tablets is 10 mg per day taken 60 minutes before intercourse. If there is no response or side effects, the dose may be increased to 20 mg or, if there are side effects, it may be reduced to 5 mg.
Individuals 65 years of age or older should begin therapy with 5 mg.
Individuals who are taking medications that increase the blood levels of vardenafil should start treatment with 2.5 to 5 mg of vardenafil. (See drug interactions.)
