Vardenafil at recommended doses has no effect in the absence of sexual stimulation.
Vardenafil potentiates the hypotensive effect of concurrently administered nitrates, therefore patients receiving nitrate therapy should be advised to use an alternate treatment for erectile dysfunction.
Some patients receiving vardenafil may experience a transient visual disturbance which makes objects appear to have a blue tint or creates difficulty distinguishing the difference between the colors blue and green. While the efficacy of sildenafil in treating erectile dysfunction is associated with its competitive inhibition of phosphodiesterase type 5 causing the release of nitric oxide in the blood vessels of the corpus cavernosum, higher doses may cause a transient inhibition of phosphodiesterase 6 located in the retina, resulting in altered blue/green color discrimination.
Vardenafil is metabolized in the liver by the cytochrome 450 enzyme system, therefore, drugs which are inhibitors or inducers of this system should be expected to alter levels of vardenafil when given concomitantly.
Caution should be exercised when prescribing vardenafil to patients with underlying cardiovascular disease, particularly patients with long QT syndrome.
