What does Levitra do to a man?

When a man takes Levitra, its job is to help him get and keep an erection when he's sexually aroused. The active ingredient, vardenafil, works by increasing blood flow to the penis. It relaxes the blood vessels down there, so when he's turned on, more blood can rush in, making the penis firm. It doesn't magically create an erection without stimulation, nor does it increase desire; it just helps the physical process work better for guys who have erectile dysfunction. Some men might experience side effects like a headache, flushing, or a stuffy nose, but the main intended effect is a more reliable and firm erection for sexual activity.
