Viagra (sildenafil) 100mg Tablets (8)

Viagra 100mg tablets is a treatment for men with erectile dysfunction. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity.

Viagra works by helping to relax the blood vessels in your penis, allowing more blood to flow into your penis when you get sexually excited. Please note that Viagra will only help you to get an erection if you are sexually stimulated. You should not take Viagra if you do not have erectile dysfunction. You should not take Viagra if you are a woman.

Like all medicines, Viagra can cause side effects although not everybody gets them. The side effects reported in association with the use of Viagra are usually mild to moderate and of a short duration. For a full list of side effects see the Patient Information Leaflet.

All medicines including Viagra can cause allergic reactions. You should contact your doctor immediately If you experience any of the following symptoms after taking Viagra: sudden wheeziness, difficulty in breathing or dizziness, swelling of the eyelids, face, lips or throat.
Prolonged and sometimes painful erections have been reported after taking Viagra. If you have an erection which lasts for more than 4 hours, you should contact a doctor immediately.

Tell your doctor
- if you have sickle cell anaemia (an abnormality of red blood cells), leukaemia (cancer of blood cells), multiple myeloma (cancer of bone marrow)
- If you have a deformity of your penis or Peyronie’s Disease.
− if you have problems with your heart. Your doctor should in that case carefully check whether your heart can take the additional strain of having sex.
− if you currently have a stomach ulcer, or a bleeding problem (such as haemophilia).
− if you experience sudden decrease or loss of vision, stop taking Viagra and contact your doctor immediately.

Please tell your doctor or pharmacist if you are taking or have recently taken other medicines, including medicines obtained without prescription.
Viagra tablets may interfere with some medicines, especially those used to treat chest pain. In the event of a medical emergency, you should tell any healthcare professional treating your condition that you have taken Viagra and when you did. Do not take Viagra with other medicines unless your doctor tells you that you can.
You should not take Viagra if you are taking medicines called nitrates as the combination of these products may cause a potentially dangerous decrease in your blood pressure. Always tell your doctor or pharmacist if you are taking any of these medicines that are often used for the relief of angina pectoris (or “chest pain”).
You should not take Viagra if you are using any of the drugs known as nitric oxide donors such as amyl nitrite (“poppers”) as the combination may also lead to a potentially dangerous decrease in your blood pressure.
If you are taking medicines known as protease inhibitors, such as for the treatment of HIV, your doctor may start you on the lowest dose (25 mg) of Viagra.
Some patients who take alpha-blocker therapy for the treatment of high blood pressure or prostate enlargement may experience dizziness or light-headedness which may be caused by low blood pressure upon sitting or standing up quickly. Certain patients have experienced these symptoms when taking Viagra with alpha-blockers. This is most likely to occur within 4 hours after taking Viagra. In order to reduce the likelihood that these symptoms occur, you should be on a regular daily dose of your alpha-blocker before you start Viagra. Your doctor may start you on a lower dose (25 mg) of Viagra.
