Levitra contains a medicine called vardenafil. It works in the same way as sildenafil, which is the active ingredient in Viagra. However, vardenafil and sildenafil are not the same substance and they are effective in different dosages.
Common dosages for Viagra are 50mg and 100mg. For Levitra, however, the most commonly prescribed dosages are 10mg and 20mg.
