Levitra Tablets 20mg contain the active ingredient, vardenafil and are used for treating erectile dysfunction, also known as male impotence. Insufficient blood flow to the penis during sexual activity prevents the ability to achieve or maintain an erection sufficient for sexual intercourse to take place.
Vardenafil acts on the erectile tissue within the penis, increasing blood flow sufficiently to cause an erection. Levitra tablets are best taken within an hour of planned sexual activity and may be effective for up to four hours, provided there is sexual stimulation taking place.
Levitra is sometimes prescribed for and may be effective in treating premature ejaculation.
