Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about Sildenafil Sandoz.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking this medicine against the benefits they expect it will have for you.

It should only be used under strict medical supervision.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

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.

Before you take Sildenafil Sandoz

You must not take Sildenafil Sandoz if you are taking any nitrates or nitrite medications. It may lead to a severe drop in blood pressure, which may be difficult to treat.

Because sexual activity may place a strain on your heart, your doctor will need to check whether you are fit enough to take Sildenafil Sandoz.

  • sildenafil, the active ingredient, or to any of the other ingredient listed at the end of this leaflet under Product Description
