IMDUR Tabs contains ISOSORBIDE-5-Mononitrate.
Isosorbide mononitrate is used to prevent chest pain (angina) in patients with a certain heart condition (coronary artery disease). This medication 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 (isosorbide mononitrate) is a nitrate that dilates (widens) blood vessels, making it easier for blood to flow through them and easier for the heart to pump.
Imdur is an extended release tablet used to prevent angina attacks (chest pain).
Imdur will not treat an angina attack that has already begun.
You should not take erectile dysfunction medicine (Viagra, Cialis, Levitra, Stendra, Staxyn, sildenafil, avanafil, tadalafil, vardenafil) while you are taking Imdur. Taking these medicine together can cause a sudden and serious decrease in blood pressure.
Seek emergency medical attention if you have early symptoms of a heart attack (chest pain or pressure, pain spreading to your jaw or shoulder, sweating, general ill feeling).
Do not stop taking this medicine suddenly. Stopping suddenly could cause a severe angina attack.
Isosorbide mononitrate can cause severe headaches, especially when you first start using it. These headaches may gradually become less severe as you continue to use the medication. Do not stop taking Imdur. Ask your doctor before using any headache pain medication.
Use this medicine regularly to prevent an angina attack. Get your prescription refilled before you run out of medicine completely.
