Typically, a dosage of 10 mg (half a pill) is advised at first. It is highly advised that you speak with your physician about the appropriate dosage for you before using Vidalista tablets. Vidalista Tablets work best when taken after a low-fat meal because eating a meal with fat slows down the tablet’s effectiveness.
