Viagra vs. Levitra

If you have erectile dysfunction (a repeated inability to maintain an erection firm enough for intercourse), a healthcare provider can recommend medications that help, such as Levitra® (vardenafil HCL) and Viagra® (sildenafil citrate). These drugs are similar in many ways, but there are also some differences to be aware of.
 
When comparing Viagra vs. Levitra, both medicines work in a similar way -- by inhibiting the chemical process that allows blood to flow out of the penis. More blood flow in the penis leads to an improved erection. Both drugs come in tablet form and are usually taken one hour before sexual activity.
 
Some differences are in the effectiveness of the drugs. Clinical studies have shown that up to 88 percent of men reported an improvement in their erections when taking Viagra, while up to 80 percent of men reported that Levitra improved their erections.
 
In addition, clinical studies have shown that Viagra typically begins to work in 14 to 30 minutes. It can continue to work for at least four hours, but, on average, the response decreases after about two hours.
 
Levitra, on the other hand, can take up to an hour to start working. In most cases, it can work for up to four hours.
