Imdur Oral

Imdur Oral Uses

Isosorbide mononitrate is used to prevent chest pain (angina). When used regularly, isosorbide can decrease the number and severity of attacks of chest pain from angina and improve your ability to exercise. This medication is called a nitrate. It works by relaxing blood vessels and allowing more blood to flow to the heart.

This medication should not be used to treat angina when it occurs. Use other medications (e.g., sublingual nitroglycerin) to relieve an angina attack as directed by your doctor. Consult your doctor or pharmacist for details.

How To Use Imdur Oral

Take this medication by mouth, usually once daily in the morning, with or without food, or as directed by your doctor. Swallow this medication whole with half a glass of water (4 ounces). Do not crush or chew the tablets. Doing so can destroy the long action of the drug and may increase your risk of side effects. You may split the tablet if your prescribed dosage requires it. Exactly follow your doctor's directions on how often to take this drug. The dosage is based on your age, medical condition and response to therapy.

Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time each day. It is important to continue taking this medication even if you feel well.

When this medication is used for a long time, it may not work as well. Different dosing may be required. Follow your doctor's instructions on how to use this product to decrease the risk that the medication will become less effective over time. Talk with your doctor if this medication stops working well.

Do not suddenly stop taking this medication without consulting your doctor. Your condition may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.

Inform your doctor if your condition worsens (e.g., the number of angina attacks increases).
