Elantan® 40mg Tablets
Read all of this leaflet carefully before you start taking this medicine because it contains important information for you.
Elantan belongs to a group of medicines called organic nitrates.
Organic nitrates work by widening the blood vessels in your heart to allow an increased amount of blood to flow to areas which need it. Elantan is used to prevent angina pectoris. Angina usually feels like a tight pain in the chest, neck or arm area. The pain comes from the heart muscle and is a sign that part of it is not getting enough oxygen for the amount of work it is doing.
Elantan 40mg tablets may also be used in conjunction with other treatments after heart attack or heart failure.
Do not take Elantan:
• if you are allergic to isosorbide mononitrate, other nitrates or any of the other ingredients of this medicine (listed in section 6)
• if you suffer from severe anaemia (reduction in red blood cells which can make the skin pale and cause weakness or breathlessness)
• if you have had a heart attack (myocardial infarction)
• if you have had a brain haemorrhage (bleeding)
• if you have had a head injury (trauma)
• if you have severely low blood volume (hypovolaemia)
• if you have severely low blood pressure
• if you are suffering from ‘shock’ as the blood has stopped circulating properly around your body (circulatory failure)
• if you take sildenafil, tadalafil or vardenafil (medicines to treat erectile dysfunction and/or pulmonary hypertension) or any other phosphodiesterase inhibitor.
• if you have an eye disease called glaucoma
• if you have been diagnosed with any of the following heart conditions: hypertrophic obstructive cardiomyopathy (HOCM), constrictive pericarditis, cardiac tamponade, low cardiac filling pressures, aortic/mitral valve stenosis and diseases associated with raised intra-cranial (head) pressure
• if you take products that contain riociguat a medicine used in treating pulmonary hypertension.
If any of the above applies to you talk to your doctor or pharmacist.
