sildenafil

Read this leaflet carefully before you start taking this medicine, because it contains important information for you.

• Keep this leaflet, as you may need to read it again.
• If you have any questions, ask your doctor or pharmacist.
• This medicine has been prescribed for you only, and you must not give it to others even if they have the same symptoms as you, as it may harm them.

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

Vizarsin is indicated for the treatment of erectile dysfunction in adult men, sometimes referred to as impotence. This occurs when a man is unable to obtain or maintain a firm, satisfactory erection for sexual activity.

Do not take Vizarsin

• If you are allergic to sildenafil or any of the other components of this medication (listed in section 6).

• If you are taking certain medications called nitrates, as the combination may lead to a dangerous drop in your blood pressure. Consult your doctor if you are taking any of these medications, which are often used to relieve chest pain (or "chest pain"). If you are unsure, consult your doctor or pharmacist.

• If you are using any of the medications called nitric oxide donors such as amyl nitrite ("poppers"), as the combination may lead to a dangerous drop in your blood pressure.

• If you are taking riociguat. This medication 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 clots). PDE5 inhibitors, such as Vizarsin, have shown to increase the hypotensive effect of this medication. If you are taking riociguat or are unsure, consult your doctor.

• If you have a severe 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 vision loss due to non-arteritic anterior ischemic optic neuropathy (NAION).

Warnings and precautions

Consult your doctor or pharmacist before starting to take Vizarsin:

• If you have sickle cell anemia (a blood disorder), leukemia (blood cancer), or multiple myeloma (bone marrow cancer).

• If you have a penile deformity or Peyronie's disease.

• If you have heart problems. Your doctor must carefully check if your heart can handle the additional strain of sexual activity.

• If you have a current stomach ulcer or bleeding problems (such as hemophilia).

• If you experience a sudden decrease or loss of vision, stop taking Vizarsin and contact your doctor immediately.

Do not use Vizarsin simultaneously with any other oral or local treatment for erectile dysfunction.

Do not take Vizarsin with treatments for pulmonary arterial hypertension (PAH) that contain sildenafil or any other PDE5 inhibitor.

Do not take Vizarsin if you do not have erectile dysfunction.

Use of Vizarsin is not indicated in women.

Use of Vizarsin with other medications

Vizarsin tablets may interact with some medications, especially those used to treat chest pain. In case of a medical emergency, you must inform your doctor, pharmacist, or nurse that you are taking Vizarsin and when you took it. Do not take Vizarsin with other medications unless your doctor advises you to.

Do not take Vizarsin if you are taking medications called nitric oxide donors, such as amyl nitrite ("poppers"), as the combination may also lead to a dangerous drop in your blood pressure. Inform your doctor or pharmacist if you are taking riociguat.

If you are taking medications known as protease inhibitors, such as those used to treat HIV, your doctor may recommend that you start treatment with the lowest dose (25 mg) of Vizarsin.

Some patients taking an alpha-blocker, a medication used to treat high blood pressure or prostate enlargement, may experience dizziness or lightheadedness that may be caused by a drop in blood pressure when sitting or standing up quickly. Some patients have experienced these symptoms when taking Vizarsin with alpha-blockers. This is more likely to occur in the 4 hours following Vizarsin intake. To reduce the likelihood of these symptoms, you should be receiving your daily dose of the alpha-blocker regularly before starting Vizarsin. Your doctor may recommend that you start treatment with the lower dose (25 mg) of Vizarsin.

Vizarsin can be taken with or without food. However, you may notice that Vizarsin takes a little longer to take effect if taken with a large meal.
