1. What Isosorbide Mononitrate Tablets are and what they are used for
Isosorbide Mononitrate Tablets belong 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.
Isosorbide Mononitrate Tablets are 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.
Isosorbide Mononitrate 20 mg Tablets can also be used to treat congestive heart failure. Heart failure can happen when the heart muscle is not strong enough to pump the blood around the body. It may cause problems with breathing and swelling of the legs.
2. What you need to know before you take Isosorbide Mononitrate Tablets

• You are allergic to isosorbide

• You have had a heart attack (myocardial infarction)
• You have had a brain haemorrhage (bleeding)
• You have had a head injury (trauma)
• You have a low blood volume (hypovolaemia)
• You have very low blood pressure
• Your blood has stopped circulating around your body properly (circulatory failure)
• You take sildenafil (“Viagra”) or any other phosphodiesterase inhibitor.
• You are suffering from “shock” or vascular collapse
• You have an eye disease called glaucoma
• You have been diagnosed with any of the following heart conditions: hypertrophic obstructive cardiomyopathy (HOCM), const-rictive pericarditis, cardiac tamponade, low cardiac filling pressures, aortic/mitral valve stenosis and diseases associated with raised intra-cranial (head) pressure.
