DISOPYRAMIDE - ORAL

(dye-soe-PIR-a-mide)

COMMON BRAND NAME(S): Norpace

WARNING: Though this medication often gives great benefits to people with irregular heartbeat, it may infrequently cause a serious new irregular heartbeat. Therefore, when starting treatment with this drug, your doctor may recommend that you stay in the hospital for proper monitoring and emergency medical treatment if needed. Talk with your doctor about the benefits and risks of taking this medication.

USES: This medication is used to treat certain types of serious (possibly fatal) irregular heartbeat, such as persistent ventricular tachycardia. It is used to restore normal heart rhythm and maintain a regular, steady heartbeat. Disopyramide is known as an anti-arrhythmic drug. It works by blocking certain electrical signals in the heart that can cause an irregular heartbeat. Treating an irregular heartbeat can decrease the risk for blood clots, and this effect can reduce your risk of heart attack or stroke.

HOW TO USE: Take this medication by mouth with or without food exactly as prescribed by your doctor. If you are taking the immediate-release form, you will usually take it 4 times daily or as directed by your doctor.

If you are taking the extended-release form, you will usually take it twice a day or as directed by your doctor. Swallow extended-release capsules whole. Do not crush or chew extended-release capsules or tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split extended-release tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.

Dosage is based on your age, kidney and liver function, medical condition, and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day.

Tell your doctor if your condition does not improve or if it worsens.
