Sildanafil Medical Information
Sildenafil contains the active substance sildenafil which belongs to a group of medicines called phosphodiesterase type 5 (PDE 5) inhibitors. It works by helping to relax the blood vessels in your penis, allowing blood to flow into your penis when you get sexually excited. Sildenafil will only help you to get an erection if you are sexually stimulated. Sildenafil is a treatment for adult men with erectile dysfunction, sometimes known as impotence. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity.
You should take Sildenafil about one hour before you plan to have sex. Swallow the tablet whole with a glass of water.
The amount of time Sildenafil takes to work varies from person to person, but it normally takes between half an hour and one hour.
Sildenafil can be taken with or without food. However, you may find that Sildenafil takes longer to start working if you take it with a heavy meal.
Drinking alcohol can temporarily impair your ability to get an erection. To get the maximum benefit from your medicine, you are advised not to drink excessive amounts of alcohol before taking Sildenafil.
