Vilitra 20 is usually prescribed for the treatment of the early stage of erectile dysfunction. It helps you get and maintain an erection during mating. If you plan to take it occasionally, as needed, it is recommended that you take one pill half an hour to an hour before having s*x. If you are taking it on the recommendation of your doctor, take the medicine according to his instructions (usually 1 pill per day). Do not take more than the recommended dose, which is one tablet a day, unless otherwise directed by your doctor. You should avoid taking the pill more than four hours before having s*x, as its potency begins to decline afterward. Also, you can take it with or without food, but the latter is better as Vilitra 60 works faster without food.You can exclude this option if you take it as needed. However, for those who have to take it daily, they may have missed a dose. In such a condition, you should take the missed dose as soon as you remember.
