Isosorbide Mononitrate ER Drug Information

• Imdur Overview

  Isosorbide mononitrate is used to prevent chest pain (angina) in patients with a certain heart condition (coronary artery disease). Imdur belongs to a class of drugs known as nitrates. It works by relaxing and widening blood vessels so blood can flow more easily to the heart. Imdur will not relieve chest pain once it occurs. Also, it is not intended to be taken just before physical activities (such as exercise or sexual intercourse) to prevent chest pain. Other medications may be prescribed by your doctor for these conditions. Consult your doctor for more details.

It is important to take the drug at the same times each day. Do not change the dosing times unless directed by your doctor. Use Imdur regularly to get the most benefit from it. To help you remember, take it at the same times each day. Do not stop taking it without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased. Although unlikely, when Imdur is used for a long time, it may not work as well and may require different dosing. Tell your doctor if Imdur stops working well (for example, you have more frequent or worsening chest pain).
