Viagra is a medication used for the treatment of erectile dysfunction. Also known as sildenafil, it works by relaxing the muscles of the penis blood vessels, and increasing blood flow to that area.
Viagra should be taken 30 minutes to an hour before having sexual intercourse. It may also be taken up to 4 hours before having sex, although it should not be taken more than once in a 24 hour period. It should be taken as prescribed.
Before taking Viagra, your medical history as well as any medications you are taking should be taken into account. If you are taking any othe type of erectile dysfunction medication such as Revatio, which is another brand of sildenafil, do not take Viagra unless advised by your doctor to do so. Certain medications can cause unwanted or dangerous side effects if used alongside Viagra, therefor it is imperative that you inform your healthcare provider of any medicines you are taking, especially if you are currently taking Adempas.
