Viagra



Viagra (sildenafil) can be prescribed to treat male impotence. This drug does not cure erectile dysfunction just treating it, which means you are supposed to take Viagra every time you are planning to have sex. Do not start taking any new drugs or herbal supplements, especially St. John's wort as they can make your treatment less efficient and cause dangerous side effects. You are supposed to take this medicine from 30 to 60 minutes before having sex and it will remain efficient for up to 4 hours. If you experience a painful erection that lasts for longer than 4 hours seek emergency help.
