1. What Sildenafil is and what it is used for
Sildenafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by helping to relax the blood vessels in your penis, allowing blood to flow into your penis when you get sexually excited. Sildenafil will only help you to get an erection if you are sexually stimulated.
Sildenafil is a treatment for adult men with erectile dysfunction, sometimes known as impotence. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity.
You must talk to a doctor if you do not feel better or if you feel worse.
2. What you need to know before you take Sildenafil
Do not take Sildenafil :
• If you are allergic to sildenafil or any of the other ingredients of this medicine (listed in section 6).
• If you are taking medicines called nitrates, as the combination may lead to a dangerous fall in your blood pressure. Tell your doctor if you are taking any of these medicines which are often given for relief of angina pectoris (or “chest pain”). If you are not certain, ask your doctor or pharmacist.
• If you are using any of the medicines known as nitric oxide donors such as amyl nitrite (“poppers”), as the combination may also lead to a dangerous fall in your blood pressure.
• If you have a severe heart or liver problem.
• If you have recently had a stroke or a heart attack, or if you have low blood pressure.
• If you have certain rare inherited eye diseases (such as retinitis pigmentosa).

You should not take Sildenafil if you are taking medicines called nitrates, as the combination of these medicines may lead to a dangerous fall in your blood pressure.

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 Sildenafil with alpha-blockers. This is most likely to happen within 4 hours after taking Sildenafil. To reduce the chance that these symptoms might happen, you should be on a regular daily dose of your alpha-blocker before you start Sildenafil. Your doctor may start you on a lower dose (25 mg) of Sildenafil.
