1. What is Sildenafilo Alter and what is it used for

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

Sildenafil is used to treat erectile dysfunction in adult men, sometimes also called impotence. This is when a man cannot get, or keep, a hard erection that is sufficient for satisfactory sexual activity.

2. What you need to know before you take Sildenafilo Alter

Do not take Sildenafilo Alter

• 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 decrease in your blood pressure. Tell your doctor if you are taking any of these medicines, often used 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 may lead to a dangerous decrease 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 sildenafil, 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 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 a loss of vision due to non-arteritic anterior ischemic optic neuropathy (NAION).

Warnings and precautions

Tell your doctor, pharmacist, or nurse before you start taking Sildenafilo:

• If you have sickle cell anemia (a disorder of the red blood cells), leukemia (cancer of the blood cells), or multiple myeloma (cancer of the bone marrow).
• If you have a deformity of the penis or Peyronie's disease.
• If you have heart problems. Your doctor should carefully check if your heart can handle the extra strain of having sex.
• If you have currently stomach ulcers or bleeding problems (such as hemophilia).
• If you experience a sudden decrease or loss of vision, stop taking sildenafil and contact your doctor immediately.

It is not recommended to use sildenafil at the same time as any other oral or local treatment for erectile dysfunction.

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

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

The use of sildenafil is not indicated in women.

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

Use of Sildenafilo Alter with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

Sildenafil tablets can interfere with some medicines, especially those used to treat angina.

Do not take sildenafil if you are taking medicines called nitric oxide donors, such as amyl nitrite ("poppers"), as the combination of these medicines can also lead to a dangerous decrease in your blood pressure.

Tell your doctor or pharmacist if you are taking riociguat.

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

Some patients who are taking an alpha-blocker, a medicine used to treat high blood pressure or an enlarged prostate, may experience dizziness or fainting that can be caused by a decrease in blood pressure when sitting or standing up quickly. Some patients have experienced these symptoms when taking sildenafil with alpha-blockers. This is more likely to happen within 4 hours of taking sildenafil. To reduce the likelihood of these symptoms, you should be taking your daily dose of the alpha-blocker regularly before starting sildenafil. Your doctor may advise you to start with the lower dose (25 mg) of sildenafil.

Tell your doctor or pharmacist if you are taking medicines that contain sacubitril/valsartan, used to treat heart failure.
