Generic Name: isosorbide dinitrate (EYE-soe-SOR-bide dye-NYE-trate)
Brand Name: Isordil Titradose
Isordil Titradose is used for:
Preventing symptoms of angina (chest pain) caused by heart disease. Isordil Titradose is used alone or with other medicines. Isordil Titradose 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.
Isordil Titradose 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.
Do NOT use Isordil Titradose if:
- you are allergic to any ingredient in Isordil Titradose
- you are taking avanafil, riociguat, sildenafil, tadalafil, or vardenafil
Contact your doctor or health care provider right away if any of these apply to you.

When used for long periods of time without a break, Isordil Titradose may not work as well. This is known as TOLERANCE.

If you take Isordil Titradose without a break and then suddenly stop taking it, you may get WITHDRAWAL symptoms. These may include chest pain, heart attack, or possibly sudden death. Be sure to have a "nitrate-free" period of time each day; this may help prevent dependence and withdrawal problems.
