Viagra is a medicine used to treat erectile dysfunction (ED, also called impotence). It is sometimes known by its generic name, sildenafil. It works by helping to relax the blood vessels in the penis, allowing blood to flow into the penis causing an erection. If you plan to use Viagra, you should take it an hour before planned sexual activity. You can get an erection for up to 4 hours after taking the Viagra although the erection itself will only last for the normal period of time https://servizio-salute.com/viagra .
