Sildenafil Online, however, can be taken as a regular daily prescription to provide background sexual stimulation. The newer agents avanafil, tadalafil and vardenafil are longer lasting and may be taken as a regular prescription on alternate days to provide background stimulation for erections. If these drugs are taken as a regular prescription, treatment should be continued for a minimum period of six weeks before their effectiveness can be adequately assessed.
