All about Generic Levitra - Vardenafil.

• The recommended dose is 10 mg taken 1 hour before sexual activity.
• A higher dose of 20 mg is available for patients whose response to the 10 mg dose is not adequate.
• Two lower doses (2.5 mg and 5.0 mg) are also available and may be necessary for patients taking other medicines or have medical conditions that may decrease the body’s ability to metabolize vardenafil.
• Levitra should not be used more than once a day.

It should not be taken with

•  Nitrates (such as nitroglycerin tablets or patches)

•  An alpha blocker: alpha blockers are medicines used to treat benign prostatic hyperplasia and high blood pressure because the combination may significantly lower blood pressure and lead to fainting or even death in some men.

•  Levitra should not be used in patients who have a rare heart condition known as “prolongation of the QT interval” because of the possibility of producing abnormal heart rhythm.

•  Levitra should not be taken by men in whom sexual activity is inadvisable because of their underlying cardiovascular status (heart condition).

•  Levitra is not recommended in patients who have suffered a heart attack or stroke within the last six months, or patients who have significantly low blood pressure, uncontrolled high blood pressure, unstable angina, severe liver impairment, or retinitis pigmentosa (an eye disorder).

The most common side effects reported in clinical trials included headache, flushing, rhinitis, and indigestion. Dizziness was reported in about two percent of patients. A small number of patients taking Levitra also reported abnormal vision.

Before taking Levitra, patients are advised to undergo a thorough medical history and physical examination to attempt to diagnose the underlying cause of the erectile dysfunction and to identify appropriate treatment.
