What is in this leaflet

This leaflet answers some common questions about Viagra.

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 Viagra against the benefits they expect it will 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. Keep this leaflet with the medicine.

You may need to read it again.

What Viagra is used for

Viagra 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.

Viagra belongs to a new 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.

Viagra will work only if you are sexually excited.

Viagra will not increase your sex drive.

Viagra is not for use in women.

This medicine is available only with a doctor`s prescription.

Before you take Viagra


When you must not take it

Do not take Viagra if:
  • 1.you are being treated for angina (chest pain) or other heart conditions with certain medicines called nitrates

    Common tradenames for other nitrate preparations include tablets such as Imdur Durule, Sorbidin, Isordil, Carvasin, Corangin, ISMO 20, Imtrate, Coronex, Duride, Ikorel and Sodium Nitroprusside.

    Taking other medicines

    Tell your doctor or pharmacist if you are taking any other medicines, including medicines you buy without a prescription from a pharmacy, supermarket or health food shop. Do not take Viagra if you are using nitrate medicines for angina.

    Some medicines and Viagra may interfere with each other. These include:

  • cimetidine, a medicine used to treat ulcers

    Ask your doctor or pharmacist, if you are not sure if you are taking any of these medicines.

    How to take Viagra

    Take Viagra exactly as your doctor has prescribed.

    Follow all directions given to you by your doctor and pharmacist carefully.

    They may differ from the information contained in this leaflet.

    If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.

    How much to take

    Your doctor will decide the correct dose for you depending on your condition and response.

    This can be one 25 mg tablet a day or one 50 mg tablet a day or one 100 mg tablet a day.

    Do not take more than one dose of Viagra a day.

    When to take it

    Take your dose of Viagra about one hour before you intend to have sex.

    Swallow the tablet whole with a full glass of water.

    The amount of time Viagra takes to start working varies from person to person, but it normally takes between half an hour and one hour.

    You may find Viagra takes longer to work if you take it with a heavy meal.

    Viagra will work only if you are sexually excited.

    If you take too much (Overdose)

    If you take too much, you are more likely to experience side effects.

    Immediately telephone your doctor or Poisons Information Centre (telephone in Australia 13 11 26; in New Zealand 0800 POISON or 0800 764 766) for advice if you think that you or anyone else may have taken too much Viagra. Do this even if there are no signs of discomfort.

    While you are using it

    Things you must do

    Stop using Viagra if you have a loss of eyesight in one or both eyes. Seek medical attention urgently.

    If Viagra does not help you get an erection or if your erection does not last long enough to complete sexual intercourse, tell your doctor.

    In these cases, your doctor may decide that you need a higher dose.

    If you are about to start taking any new medicines, especially nitrates, tell your doctor and pharmacist that you are taking Viagra. See "Before you take Viagra" for a list of common nitrate medications.
  • Tell any other doctors, dentists and pharmacists who are treating you that you are taking Viagra.

    Things you must not do

    Do not use the drug amyl nitrite (sometimes called "poppers") while you are taking Viagra. If you get an angina attack do not take nitrate medicines to relieve the pain but tell your doctor immediately. Make sure your doctor knows you are taking Viagra. Do not give Viagra to anyone else, even if they have the same condition as you.

    Things to be careful of

    Be careful drinking alcohol while taking Viagra.

    Drinking alcohol can temporarily impair the ability to get an erection.

    Do not drink large amounts of alcohol before sexual activity.

    If you experience changes in vision, or dizziness, when taking Viagra, you should not drive or operate machinery.

    Side effects

    Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Viagra.

    While Viagra helps most people it can cause some unwanted side effects in a few people. All medicines have side effects. If unwanted effects occur, most are likely to be minor and temporary. However, some may be serious and need medical attention.

    Do not be alarmed by this list of possible side effects.

    You may not get any of them.
  • Tell your doctor or pharmacist if you notice any of the following and they worry you:
  • headache, dizziness
  • flushing
  • indigestion
  • stuffy nose
  • changes in vision such as blurring, a blue colour to your vision or a greater awareness of light
  • diarrhoea
  • urinary tract infection (stinging or burning urine, more frequent need to pass urine)
  • rash.
  • Very rarely 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.

    Rarely men have lost eyesight some time after taking drugs to treat erectile dysfunction (known as impotence). It is not known at this time if Viagra causes this. If you lose eyesight in one or more eyes, seek medical attention urgently.

    This is not a complete list of all possible side effects. Others may occur in some people and there may be side effects not yet known.

    If you notice any other symptoms that worry you, check with your doctor. Ask your doctor or pharmacist if you don`t understand anything in this list.

    After using Viagra


    Keep this medicine where children cannot reach it.

    A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

  • Keep Viagra in a cool, dry place where the temperature stays below 30 degrees C. Do not store it or any other medicine in the bathroom or near a sink. Do not leave it in the car or on windowsills.

    Heat and dampness can destroy some medicines.

    Keep the tablets in their pack until it is time to take them. If you take your tablets out of the pack they will not keep as well.


    If your doctor tells you to stop taking Viagra, or the tablets have passed their expiry date, ask your pharmacist what to do with any left over.
