What Sildenafil Sandoz is used for
This medicine is used to treat erectile dysfunction, more commonly known as impotence in men. This is when a man cannot get, or keep a hard erect penis suitable for sexual activity.
It contains the active ingredient sildenafil. Sildenafil belongs to a group of medicines called phosphodiesterase type 5 inhibitors.
It works by relaxing the blood vessels in your penis when you are sexually excited. This allows blood to flow into your penis, allowing you to get an erection in the natural way.
Sildenafil Sandoz will work only if you are sexually excited. It will not increase your sex drive.
Sildenafil Sandoz is not for use in women.
This medicine is available only with a doctor's prescription.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
