Uses

What is Risordan® (isosorbide dinitrate) used for?

Risordan® is a nitrate. It works by relaxing the blood vessels in the body, allowing them to widen. This lets more blood flow through the blood vessels, which reduces the work the heart has to do to pump blood. This reduces the oxygen needs of the heart and decreases chest pain.

It is commonly used for preventing symptoms of angina (chest pain) caused by heart disease. Risordan® is used alone or with other medicines.

Risordan® is not intended for the immediate relief of acute attacks of angina. It may also be used for other conditions as determined by your doctor.

How should I take Risordan® (isosorbide dinitrate)?

  • If you expect to engage in an activity that may cause angina, take the sublingual tablet about 15 minutes before the activity.
  • If you use the sublingual tablet to treat an angina attack that has already begun, use the medicine at the first sign of chest pain. Place the tablet under your tongue and allow it to dissolve slowly. Do not chew or swallow it.
  • It is important to keep this medicine on hand at all times in case of an angina attack. Get your prescription refilled before you run out of medicine completely.
