Vilitra 40 mg works only when there is sexual arousal. It does not create an erection automatically. Instead, it enhances the natural erectile response by relaxing blood vessels in the genital area and allowing better blood circulation. This higher-strength dose is usually taken about 30 to 60 minutes before sexual activity. The effects typically last around 4 to 6 hours, depending on individual factors such as age, metabolism, diet, and overall health.
