What is in this leaflet

All medicines have risks and benefits. Your doctor has weighed the risks of you taking SILARAN against the benefits it is expected to have for you.
It should be used only under strict medical supervision. If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What SILARAN is used for
SILARAN is used to treat erectile dysfunction, more commonly known as impotence, in adult men. This is when a man cannot get, or keep, a hard erect penis suitable for sexual activity.
Sildenafil citrate belongs to a group of medicines called phosphodiesterase type 5 inhibitors. It works by relaxing the blood vessels in the penis when you are sexually excited. This allows blood to flow into your penis, allowing you to get an erection naturally.
SILARAN will only work if you are sexually excited. It will not increase your sex drive.
SILARAN is not for use in women.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
This medicine is available only with a doctor’s prescription.
Before you take SILARAN
YOU MUST NOT TAKE SILARAN IF YOU ARE TAKING ANY NITRATE MEDICATION. IT MAY LEAD TO A SEVERE DROP IN YOUR 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 SILARAN.

If you take too much (overdose)
If you are taking more than the recommended dose of SILARAN, you are more likely to experience side effects.
Immediately telephone your doctor or the Poisons Information Centre (13 11 26), or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much SILARAN.
Do this even if there are no signs of discomfort. You may need urgent medical attention. Keep telephone numbers of these facilities handy.

- You have an erection that persists for more than 4 hours
If you experience any of the above while taking SILARAN, you need to seek medical attention urgently.
Tell your doctor in case SILARAN does not help you get an erection or if your erection does not last long enough to complete sexual intercourse. In such cases, your doctor may recommend a higher dose.
If you are about to be started on any new medicine, especially nitrates, tell your doctor and pharmacist that you are taking SILARAN.

If you have an angina attack, do not take nitrate medicines but tell your doctor immediately, and tell him/her that you are taking SILARAN.

If you experience dizziness or change in vision when taking SILARAN, do not drive or operate machinery.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking SILARAN.
SILARAN helps most people suffering from erectile dysfunction (or impotence), but it may have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Do not be alarmed by the following list of side effects. You may not experience any of them.
Tell your doctor if you notice any of the following and they worry you:
- an uncomfortable feeling in the stomach or belching after eating
- nasal congestion
These side effects are more common and are usually mild and short-lived.
Tell your doctor as soon as possible if you notice any of the following:
- unusual heart beat
- urinary tract infection (stinging or burning sensation, need to pass urine more frequently)
- blood in the urine
- changes in vision such as blurring, a blue tinge to your vision or being more sensitive to light
- persistent headache or fainting
- bleeding from the nose
These may be serious side effects. You may need urgent medical attention. Serious side effects are rare.
If any of the following happens, tell your doctor immediately or go to Accident and Emergency at your nearest hospital:
- signs of allergy such as shortness of breath, wheezing or difficulty in breathing, swelling of the face, lips, tongue or other parts of the body
- chest pain
- sudden decrease or loss of hearing
- seizures, fits or convulsions
- your erection may persist for longer than usual. If your erection continues for four hours, or sooner if there is pain, you should seek medical attention urgently. This very rarely happens.
- men have lost eyesight some time after taking drugs to treat erectile dysfunction (or impotence) on rare occasions. It is not known at this time if SILARAN causes this. If you lose eyesight in one or more eyes, seek medical attention urgently.
Other side effects not listed above may also occur in some patients. Tell your doctor if you notice anything else that is making you feel unwell.
Ask your doctor or pharmacist if you don’t understand anything in this list.
