How long before sex should I take Levitra?

The instructions for taking Levitra are nearly identical to those for taking Viagra: 25 to 60 minutes before you plan to have sex. Anecdotal evidence points to Levitra taking effect a little more quickly than Viagra, but in general you can expect the effect to be about the same. As with Viagra, the half-life of Levitra is four to six hours. Unlike Viagra, however, Levitra doesn’t appear to be affected by whether or not you take it with food. Therefore, if you take your Levitra with dinner, you shouldn’t expect it to be any different than if you took it on an empty stomach.
