How does sildenafil work?

Sildenfil works by increasing blood flow to the penis, in turn helping men to get and maintain an erection.

It should be noted that men will still require sexual stimulation, as sildenafil doesn't have an active impact on libido.

The effectiveness of any erectile dysfunction drug can vary. As such, if you find that taking Sildenafil doesn't help you to get and maintain an erection the first time, it might work more effectively the next.

Doctors typically suggest trying all forms of erectile dysfunction drugs 8 times before giving up. 

How to take Sildenafil

Take one tablet of Sildenafil one hour before having sex, as it takes 30-60 minutes for it to work. For optimum performance, Sildenafil should be taken on an empty stomach and you should not drink excessive amounts of alcohol, as it can make the drug ineffective.
