Mononit 10, Mononit 20, Mononit 40 is used for the long-term treatment of angina pectoris (chest pain and tightness) and for preventing angina attacks.

2. Important information before taking Mononit 10, Mononit 20, Mononit 40

• if the patient has severe heart muscle or pericardium diseases causing significant impairment of heart function (so-called hypertrophic cardiomyopathy, constrictive pericarditis, cardiac tamponade);
• if the patient is concurrently taking medicines used to treat erectile dysfunction (medicines from the phosphodiesterase-5 inhibitor group, e.g. sildenafil, vardenafil, tadalafil). Treatment with isosorbide mononitrate must not be discontinued in order to take a medicine containing a phosphodiesterase-5 inhibitor, as this may increase the risk of angina attacks (see "Mononit 10, Mononit 20, Mononit 40 and other medicines");
• if the patient has very low arterial blood pressure (hypotension) (systolic pressure below 90 mm Hg);
• if the patient has severe hypovolemia (reduced blood volume in vessels);
• if the patient is concurrently taking riociguat (a medicine used to treat pulmonary hypertension);
• if the patient has severe anaemia (reduced number of red blood cells, which may manifest as skin pallor, weakness, and shortness of breath).

Warnings and precautions
Before starting treatment with Mononit 10, Mononit 20, Mononit 40, discuss this with your doctor or pharmacist.
Exercise special caution when using Mononit 10, Mononit 20, Mononit 40:

• if the patient has low ventricular filling pressure, e.g. in acute myocardial infarction, impaired left ventricular function; avoid reducing systolic blood pressure below 90 mm Hg;
• if the patient has aortic and/or mitral valve stenosis;
• if the patient is prone to fainting associated with sudden body uprighting, e.g. upon waking in the morning (orthostatic circulatory disorders);
• if the patient has conditions associated with increased intracranial pressure;
• if the patient has liver function disorders;
• if the patient has a disease of the eye called glaucoma;
• if the patient has hyperthyroidism (overactivity of the thyroid gland, which may manifest as increased appetite, weight loss, and sweating);
• if the patient has reduced activity of the enzyme glucose-6-phosphate dehydrogenase (G6PD), which may manifest as haemolytic anaemia.

Mononit 10, Mononit 20, and Mononit 40 are not intended for the treatment of acute angina attacks or acute myocardial infarction.
