1. What is Ervasil and what is it used for
Ervasil 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. Ervasil helps achieve an erection only if there is prior sexual stimulation. Ervasil is used to treat erectile dysfunction in adult men, which is the inability to achieve or maintain an erection sufficient for sexual intercourse.
2. Important information before taking Ervasil
When not to take Ervasil
- 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 is a medicine 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, 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 had a loss of vision due to non-inflammatory anterior ischemic optic neuropathy.
Warnings and precautions
Before starting to take Ervasil, the patient should discuss it with their doctor or pharmacist in the following cases:
- Sickle cell anemia (a disorder affecting red blood cells), leukemia (a blood cancer), or 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 strain associated with sexual activity.
- Ulcer or bleeding disorders (such as hemophilia).
- If the patient experiences sudden vision loss or sudden blindness, they should stop taking Ervasil and seek medical help immediately.
Ervasil should not be taken at the same time as other oral or topical treatments for erectile dysfunction. Ervasil should not be taken at the same time as treatments for pulmonary arterial hypertension (PAH) using sildenafil or other PDE5 inhibitors. Ervasil should not be taken if erectile dysfunction has not been diagnosed. Ervasil is not intended for women. Special considerations for patients with renal or hepatic impairmentPatients with renal or hepatic impairment should inform their doctor. Patients with renal or hepatic impairment should not take a dose of Ervasil higher than 25 mg.
Children and adolescents
Ervasil should not be taken by persons under 18 years of age.
Ervasil 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. Ervasil may interact with some medicines, especially those used to treat chest pain. If the patient's condition worsens, requiring immediate medical attention, they should inform their doctor, pharmacist, or nurse about taking Ervasil and the time of its administration. Ervasil should not be taken with other medicines without a doctor's recommendation. Ervasil should not be taken if the patient is taking nitrates, 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"). Ervasil should not be taken if the patient is 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 protease inhibitors used to treat HIV infections, it is recommended to start treatment with a lower dose (25 mg) of Ervasil. In some patients who take 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 or sitting down quickly. Such symptoms occurred in some patients taking Ervasil and alpha-adrenergic blockers. Their occurrence is most likely within 4 hours of taking Ervasil. To reduce the possibility of these symptoms, the patient should regularly take their fixed dose of alpha-adrenergic blocker before starting to take Ervasil. The doctor may decide to use a lower initial dose (25 mg) of Ervasil. If symptoms of low blood pressure (dizziness, lightheadedness, feeling of impending faint) occur, the patient 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 or sitting down quickly. If the patient is taking medicines containing sacubitril with valsartan (used to treat heart failure), they should inform their doctor or pharmacist.
Ervasil with food, drink, and alcohol
Ervasil can be taken with or without food. Although taking Ervasil during a heavy meal may prolong the time needed for the medicine to start working. The ability to achieve an erection may be temporarily impaired after consuming alcohol. To maximize the therapeutic benefits of Ervasil, the patient should not consume large amounts of alcohol before taking the medicine.
