1. What Zuandol is and what it is used for

Zuandol contains the active substance sildenafil, which belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by dilating the blood vessels in the penis, allowing blood flow when you are sexually stimulated. Zuandol will only help you to get an erection if you are sexually stimulated.

Zuandol is indicated for the treatment of male erectile dysfunction, sometimes called impotence. This occurs when a man cannot get or maintain an erection that is sufficient for satisfactory sexual activity.

2. What you need to know before you take Zuandol

Do not take Zuandol

• 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 can cause a dangerous drop in your blood pressure. Consult your doctor if you are taking any of these medicines, which are often given to relieve angina pectoris (or "chest pain"). If you are not sure, consult 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 can cause a dangerous drop in your blood pressure.
• If you are taking riociguat. This medicine is used to treat pulmonary arterial hypertension (i.e., high blood pressure in the lungs) and chronic thromboembolic pulmonary hypertension (i.e., high blood pressure in the lungs caused by blood clots). PDE5 inhibitors, such as Zuandol, have shown that they increase the hypotensive effect of this medicine. If you are taking riociguat or are not sure, consult your doctor.
• If you have a serious heart or liver problem.
• If you have recently had a stroke or heart attack, or if you have low blood pressure.
• If you have a rare inherited eye disease, such as retinitis pigmentosa.
• If you have previously experienced a loss of vision due to non-arteritic anterior ischemic optic neuropathy (NAION).

• If you have heart problems. In this case, your doctor should carefully check if your heart can withstand the extra strain of having sex.
• If you have a stomach ulcer or bleeding problems (such as hemophilia).
