■ 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.
Some patients who take alpha-blocker therapy for the treatment of high blood pressure or prostate enlargement may experience dizziness or light-headedness which may be caused by low blood pressure upon sitting or standing up quickly. Certain patients have experienced these symptoms when taking sildenafil with alpha-blockers. This is most likely to happen within 4 hours after taking sildenafil. In order to reduce the chance that these symptoms might happen, you should be on a regular daily dose of your alpha-blocker before you start sildenafil. Your doctor may start you on a lower dose (25mg) of sildenafil.
