Reduction of erectile dysfunction
What is it?
Medication that chemically assists erections of the penis.
It's also known as Levitra.
How long does it last?
Vardenafil takes around half an hour to take effect, and the effects may last for several hours.
Alternatives to vardenafil include tadalafil and sildenafil.
While tadalafil does have a longer lasting action than sildenafil and vardenfil, there is no evidence that any of the treatments is more effective than the others 1.
There is good medical evidence that all three treatments are safe 2, with the vast majority of side effects being minor (flushing, headaches, temporary back pain) and subsiding within a few weeks of treatment 3.
