1. What is Princex and what is it used for

Princex contains the active substance sildenafil, which belongs to a group of medicines called phosphodiesterase type 5 inhibitors. The medicine works by helping to relax the blood vessels in the penis, increasing blood flow to the penis during sexual stimulation. Princex helps to achieve an erection only if the patient is sexually stimulated. Princex is used to treat erectile dysfunction in adult men, which is defined as the inability to achieve or maintain an erection sufficient for sexual intercourse.

2. Important information before taking Princex

When not to take Princex:

• if the patient is allergic to sildenafil or any of the other ingredients of this medicine (listed in section 6),
• if the patient is taking nitrates, as their simultaneous intake may cause a dangerous drop in blood pressure. The patient should inform their doctor if they are taking any medicines from this group, which are often used to relieve symptoms of angina pectoris ("chest pain"). In case of doubt, the patient should consult their doctor or pharmacist,
• if the patient is taking medicines that release nitric oxide, such as amyl nitrite ("poppers"), as their simultaneous intake may also cause a dangerous drop in blood pressure,
• if the patient is taking riociguat. This medicine is used to treat pulmonary 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). It has been shown that PDE5 inhibitors, such as Princex, enhance the blood pressure-lowering effect of this medicine. If the patient is taking riociguat or is unsure, they should inform their doctor.

This medicine should not be taken if the patient has severe heart or liver disease, if the patient has recently had a stroke or heart attack, or if the patient has low blood pressure.

• if the patient has certain rare hereditary eye diseases, such as retinitis pigmentosa,
• if the patient has ever had a sudden loss of vision due to non-arteritic anterior ischemic optic neuropathy (NAION),

Warnings and precautions

Before starting to take Princex, the patient should discuss it with their doctor or pharmacist:

• if the patient has sickle cell anemia (a disorder affecting red blood cells), leukemia (a blood cancer), or multiple myeloma (a blood cancer),
• if the patient has a physical deformity of the penis or Peyronie's disease,
• if the patient has heart problems. In this case, the doctor should assess whether the patient's heart condition allows for the additional strain associated with sexual activity,
• if the patient has stomach ulcers or bleeding disorders (such as hemophilia),
• if the patient experiences sudden vision loss or sudden hearing loss, they should stop taking Princex and seek medical attention immediately.

Princex should not be taken with other oral or topical treatments for erectile dysfunction. Princex should not be taken with treatments for pulmonary arterial hypertension (PAH) that contain sildenafil or other PDE5 inhibitors. Princex should not be taken if the patient does not have erectile dysfunction. Princex is not intended for women.
