Vilitra 10 is a prescription medication used to treat erectile dysfunction (ED). It belongs to a class of drugs called phosphodiesterase type 5 inhibitors (PDE5 inhibitors). Vilitra 10 works by relaxing blood vessels and increasing blood flow to the penis during sexual stimulation. This helps you to achieve and maintain an erection. Vilitra 10 is available as a tablet that you take orally. It comes in three different doses: 5 mg, 10 mg, and 20 mg. The recommended starting dose for most men is 10 mg. If you are taking certain other medications, your healthcare provider may start you at a lower dose. It is important to take Vilitra 10 exactly as prescribed by your healthcare provider. Do not take more or less than directed. If you miss a dose, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and continue with your regular schedule.
