About Viagra

  • Taking Viagra

    Take one tablet 1hr before sex. Works best on an empty stomach. Effects can last for up to 4hrs. Never take more than one tablet within 24hrs. Alcohol will limit Viagra's effectiveness. Do not combine Viagra with other ED medicines.

  • How it works

    Viagra's active ingredient (sildenafil citrate) increases blood flow to the penis. It enables a firmer, longer-lasting erection if you are sexually aroused.

    The treatment will not resolve the underlying physical cause of your ED or increase your sexual desire.

  • Side effects

    Side effects are uncommon, but can include nausea, vomiting, back pain, diarrhoea and an allergic rash. Some men also experience facial flushing, headaches, light headedness, nasal congestion, indigestion, palpitations (racing heartbeat), and blurred vision.

    For full information on side effects and correct use, see the patient information leaflet.

  • Effectiveness

    Viagra treats ED in 60-70% of cases. If you have eaten a large meal or drunk more than 1-2 units of alcohol, you may find Viagra is less effective.

    We advise trying an ED treatment 8 times before giving up, considering a higher dose, or seeking an alternative.

  • Strength and dosage

    The standard dose is 50mg. Depending on your age, height and weight, the cause and the severity of your ED, you may be prescribed a lower dose of 25mg, or a higher one of 100mg. Dosage does not affect how quickly or for how long the treatment works.

    Higher doses come with an increased chance of developing side effects.

  • Safety: taking other medicines

    If you are taking alpha-blockers (such as doxazosin or tamsulosin), you should wait at least 6 hours between taking those and taking Viagra.

    You will be unsuitable for Viagra if you are taking nicorandil or nitrates, such as GTN spray or isosorbide mononitrate tablets to treat angina.

    It is important that you let us know which prescription, over-the-counter medicines and recreational drugs you are taking so that we can prescribe Viagra safely.

  • Alternative treatments

    Some men find counselling helpful as a means of exploring and treating psychological causes for ED.

    If Viagra does not work for you, contact us via your Patient Record so that we can discuss your treatment options. View all our ED treatments.

  • Reordering & subscription

    To reorder Viagra, go to your Patient Record and select ‘reorder’. You will be required to fill in the online questionnaire each time you reorder.
