1. What Zuandol is and what it is used for

Zuandol contains the active substance sildenafilo, 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 sexually stimulated. Zuandol will only help achieve an erection if you are sexually stimulated.

Zuandol is indicated for the treatment of male erectile dysfunction, sometimes referred to as impotence. This occurs when a man is unable to achieve or maintain a firm erection suitable for satisfactory sexual activity.

2. What you need to know before taking 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 may cause a dangerous drop in your blood pressure. Consult your doctor if you are taking any of these medicines, which are often prescribed to relieve angina pain (or “chest pain”). If you are unsure, consult your doctor or pharmacist.
If you are using any medicines known as nitric oxide donors such as amyl nitrite (“poppers”), as the combination may 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 been shown to increase the hypotensive effect of riociguat. 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 sudden vision loss due to non-arteritic anterior ischemic optic neuropathy (NAION).

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before taking Zuandol:

If you have sickle cell anemia (an abnormality of red blood cells), leukemia (cancer of blood cells), or multiple myeloma (cancer of the bone marrow).
If you have a penile deformity or Peyronie’s disease.
If you have heart problems. In such cases, your doctor should carefully assess whether your heart can tolerate the additional strain of sexual activity.
If you currently have a stomach ulcer or bleeding disorders (such as hemophilia).
If you experience sudden decrease or loss of vision, stop taking Zuandol and contact your doctor immediately.

It is not recommended to use Zuandol together with any other oral or local treatments for erectile dysfunction.

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

You should not take Zuandol if you do not have erectile dysfunction.

The use of Zuandol is not indicated in women.

Children and adolescents

Zuandol is not indicated for use in individuals under 18 years of age.

Special considerations in patients with kidney or liver problems

Inform your doctor if you have kidney or liver problems. Your doctor may decide to reduce your dose.

Other medicines and Zuandol

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Zuandol tablets may interact with certain medicines, especially those used to treat chest pain. In a medical emergency, you must inform your doctor, pharmacist, or nurse that you are taking Zuandol and when you took it. Do not take Zuandol with other medicines unless your doctor advises you to do so.

Do not take Zuandol if you are taking medicines called nitrates, as the combination of these medicines may cause a dangerous drop in your blood pressure. Always inform your doctor, pharmacist, or nurse if you are taking any of these medicines, which are often used to relieve angina (or “chest pain”).

Do not take Zuandol if you are taking medicines known as nitric oxide donors, such as amyl nitrite (“poppers”), as combining these products may also lead to a dangerous drop in blood pressure.

Inform your doctor or pharmacist if you are taking riociguat.

If you are taking protease inhibitors, such as those used in the treatment of HIV, your doctor may recommend starting treatment with the lowest dose (25 mg) of sildenafil.

Some patients receiving an alpha-blocker, a medicine used to treat high blood pressure or benign prostatic hyperplasia, may experience dizziness or lightheadedness caused by a drop in blood pressure when sitting or standing up quickly. Some patients have experienced these symptoms when taking Zuandol with alpha-blockers. This is more likely to occur within 4 hours after taking Zuandol. To reduce the likelihood of these symptoms, you should already be on a regular daily dose of the alpha-blocker before starting Zuandol. Your doctor may advise you to start treatment with the lowest dose (25 mg) of sildenafil.

Inform your doctor or pharmacist if you are taking medicines containing sacubitril/valsartan, used to treat heart failure.

Use of Zuandol with food, drinks, and alcohol

Zuandol can be taken with or without food. However, you may notice that Zuandol takes slightly longer to work if taken with a heavy meal.

Alcohol intake may temporarily impair your ability to achieve an erection. Therefore, to achieve the maximum benefit from the medicine, it is advisable not to consume large amounts of alcohol before taking Zuandol.

Pregnancy, breastfeeding, and fertility

The use of Zuandol is not indicated in women.

Driving and using machines

Zuandol may cause dizziness and affect vision. You should know how you react to Zuandol before driving or operating machinery.

Zuandol contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per tablet; essentially “sodium-free”.

3. How to take Zuandol

Follow exactly the instructions for administration of this medicine as given by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

The recommended starting dose is 50 mg.

Do not take Zuandol more than once a day.

Do not take Zuandol film-coated tablets together with other medicines containing sildenafil.

You should take Zuandol approximately one hour before planning to have sexual intercourse. Swallow the tablet whole with a glass of water.

If you notice that the effect of this medicine is too strong or too weak, inform your doctor or pharmacist.

Zuandol will only help you achieve an erection if you are sexually stimulated. The time needed for the medicine to take effect varies from person to person, but generally ranges between half an hour and one hour. The effect of this medicine may be delayed if taken with a heavy meal.

If Zuandol does not help you achieve an erection or if the erection does not last long enough to complete sexual intercourse, consult your doctor.

If you take more Zuandol than you should

You may experience an increase in adverse effects and their severity. Doses higher than 100 mg do not increase efficacy.

Do not take more tablets than recommended by your doctor.

Contact your doctor if you have taken more tablets than advised. You may also consult your pharmacist immediately or call the Toxicology Information Service at telephone number 915 620 420, stating the medicine and the amount ingested.
