Staxyn can work quickly, but you should give it 30 minutes to take effect. Staxyn contains the same active ingredient as Levitra (vardenafil), but it’s formulated in a quick-dissolve tablet that you place under your tongue. Some men prefer this, since they don’t have to take Staxyn with water. When the drug dissolves under the tongue, it enters the bloodstream somewhat faster than if you were to swallow it whole, as you would with traditional Levitra.
Nonetheless, doctors recommend taking Staxyn a half-hour to a full hour before sex to ensure that it has enough time to become effective. Like Levitra, Staxyn has a half-life of four to six hours.
