Isosorbide mononitrate (generic for Imdur) is a prescription medication known as a vasodilator. It is used to manage chest pain (angina) that is caused by coronary artery disease (a narrowing of the blood vessels that carry blood to the heart).

Vasodilators work by relaxing the blood vessels allowing more blood and oxygen to flow to the heart while lessening its workload.

The most common side effects of Isosorbide mononitrate are headache, dizziness, lightheadedness, nausea, and flushing. These will generally go away as your body adjusts to the medication. A headache is often a sign that the medication is working and your doctor may recommend treatment with over-the-counter pain relievers such as acetaminophen or aspirin. Tell your doctor if the headaches are severe or don’t go away.

To minimize lightheadedness and dizziness, stand up slowly.

Severe adverse reactions to isosorbide mononitrate are rare, but can occur. Tell your doctor right away if you have any serious problems or allergic reactions to this medication.
