1. What is Ervasil Max and what is it used for
Ervasil Max contains the active substance sildenafil, which belongs to a group of medicines called phosphodiesterase type 5 inhibitors (PDE5). The medicine works by helping to relax the blood vessels in the penis, increasing blood flow to the penis during sexual stimulation. Ervasil Max helps achieve an erection only if there is prior sexual stimulation. Ervasil Max 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 Ervasil Max
When not to take Ervasil Max
- 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 concurrent use may lead to a dangerous decrease in blood pressure. The patient should inform their doctor if they are taking any medicines from this group - these medicines 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, so-called poppers),
as their concurrent use may also lead to a dangerous decrease 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 Ervasil Max, enhance the blood pressure-lowering effect of this medicine. If the patient is taking riociguat or is unsure, they should inform their doctor.
- If the patient has severe heart or liver disease.
- If the patient has recently had a stroke or heart attack, as well as in cases of low blood pressure.
- If the patient has hereditary degenerative retinal disorders, such as retinitis pigmentosa.
- If the patient has ever experienced sudden vision loss due to non-arteritic anterior ischemic optic neuropathy.
Warnings and precautions

- Sickle-cell anemia (a disorder affecting red blood cells), leukemia (a blood cancer), multiple myeloma (a bone marrow cancer).
- If the patient has anatomical deformation of the penis or Peyronie's disease.
- Heart problems. In this case, the doctor should assess whether the patient's heart condition allows for the additional effort associated with sexual activity.
- Peptic ulcer or bleeding disorders (such as hemophilia).
- If the patient experiences sudden vision loss or sudden blindness, they should stop taking Ervasil Max and immediately consult their doctor.

Ervasil Max and other medicines
The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.

If the patient's condition worsens, requiring immediate medical attention, they should inform their doctor, pharmacist, or nurse about taking Ervasil Max and the time of its administration. The patient should not take Ervasil Max concurrently with other medicines without their doctor's recommendation. The patient should not take Ervasil Max if they are taking nitrate medicines, as their concurrent use may lead to a dangerous decrease in blood pressure. The patient should always inform their doctor or pharmacist if they are taking nitrates, which are used to treat angina pectoris (chest pain). The patient should not take Ervasil Max if they are taking medicines that release nitric oxide (such as amyl nitrite), as their concurrent use may also cause a dangerous decrease in blood pressure. If the patient is already taking riociguat, they should inform their doctor or pharmacist. When taking medicines from the protease inhibitor group, used to treat HIV infections, the patient should consult their doctor before taking Ervasil Max; in such cases, it is recommended to start treatment with a lower dose (25 mg) of sildenafil. In some patients taking alpha-adrenergic blockers for high blood pressure or prostate enlargement, dizziness or lightheadedness may occur, which can be symptoms of low blood pressure caused by a drop in blood pressure when standing up quickly or sitting down. Such symptoms occurred in some patients taking Ervasil Max and alpha-adrenergic blockers. Their occurrence is most likely within 4 hours after taking Ervasil Max. To reduce the possibility of these symptoms, the patient should regularly take their fixed dose of alpha-adrenergic blocker before starting to take Ervasil Max. The doctor may decide to use a lower initial dose (25 mg) of Ervasil Max. If the patient experiences symptoms of low blood pressure (dizziness, lightheadedness, feeling of impending faint), they should first lie down or sit and wait for the symptoms to pass; drinking water, taking fresh air, tensing abdominal muscles, or crossing legs may also help. The patient should avoid standing up quickly or sitting down. If the patient is taking ketoconazole (an antifungal medicine), erythromycin (an antibiotic), or cimetidine (a medicine for heartburn), they should consult their doctor before taking Ervasil Max.
