Vilitra 40 Mg is a medication used to treat erectile dysfunction (ED). It is a phosphodiesterase type 5 (PDE5) inhibitor, which works by increasing blood flow to the penis during sexual stimulation, resulting in an erection. Vilitra 40 Mg is taken orally, typically 30 minutes to 1 hour before sexual activity. It is important to note that Vilitra 40 Mg does not cause an erection on its own; sexual stimulation is required for it to work.
