Using antiarrhythmic medications, such as disopyramide, may make death more likely. Inform your physician if you suffer from cardiac problems, such as heart failure or a valve issue (HF; condition in which the heart cannot pump enough blood to other parts of the body). Make a quick call to your doctor if you encounter any of the following signs: chest pain or erratic heartbeat.

Disopyramide concerns should be discussed with your doctor. Disopyramide may make arrhythmias (irregular heartbeats) more likely, and it hasn’t been shown to make it easier for people to live longer who don’t have life-threatening arrhythmias.

Some kinds of irregular heartbeats are treated with disopyramide). Disopyramide belongs to the class of drugs known as antiarrhythmic drugs. It functions by strengthening your heart’s defences against aberrant activity.

Extended-release (long-acting) capsules and capsules for oral administration of disopyramide are both available. Every 6 or 8 hours, disopyramide capsules can be used. Every 12 hours, the extended-release capsule is typically consumed. Ask your doctor or chemist to explain any instructions on your prescription label that you are unsure about following. Follow the disopyramide directions exactly. Never take it in larger or less amounts or more frequently than directed by your doctor.

Do not open, chew, or crush the extended-release capsules; simply swallow them.

Disopyramide aids in managing your disease but cannot reverse it. Disopyramide should still be used even if you feel fine. Without consulting your doctor, do not discontinue taking disopyramide.

Ask your doctor or chemist for more details if you’re interested in using this medication for any other conditions.

Before taking disopyramide,

• If you have any allergies, including to disopyramide, any other medications, or any of the substances in disopyramide capsules, notify your doctor right away. Get a list of the ingredients from your chemist.
• Inform your doctor and chemist about any additional prescription and over-the-counter drugs, vitamins, dietary supplements, and herbal products you are now taking or intend to use. Clarithromycin, erythromycin (E.E.S., Eryc, Erythrocin, others), phenytoin (Dilantin, Phenytek), propranolol (Inderal, Innopran), and verapamil should all be mentioned (Calan, Tarka, Verelan). Your physician might need to adjust the dosage of your drugs or keep a close eye on you for side effects.
• Inform your doctor if you have heart block (a disease in which electrical signals from the upper chambers of the heart are not properly transmitted to the lower chambers) or if your QT interval has ever been prolonged (condition that increases the risk of developing an irregular heartbeat that may cause fainting or sudden death). Your physician might advise against taking disopyramide.
• If you have or have ever had heart disease, diabetes, glaucoma, myasthenia gravis (a nerve system ailment that causes muscle weakness), urinary retention, benign prostatic hypertrophy, kidney, or liver disease, let your doctor know.
• Inform your physician if you are nursing a baby, intend to get pregnant, or are already pregnant. Call your doctor if you become pregnant while taking disopyramide.
• If you are 65 years of age or older, discuss the advantages and disadvantages of taking disopyramide with your doctor. Disopyramide is typically not recommended for usage in older adults since it is less reliable and less efficient than alternative drugs that can be used to treat the same disease.
• Inform your doctor or dentist that you are taking disopyramide if you are having surgery, including dental surgery.
• Consult your doctor about whether drinking alcohol is safe while taking disopyramide. Disopyramide side effects can be exacerbated by alcohol.

If you miss a dosage, take it as soon as you recall. If the next dose is soon due, skip the missed one and carry on with your regular dosing plan. To make up for a missing dose, do not take a second one.
