Disopyramide
About Disopyramide
Disopyramide is an oral prescription medication used to treat and manage certain types of serious, life-threatening irregular heartbeats (arrhythmias). It helps keep your heart beating in a normal, steady rhythm. This medicine is typically prescribed for individuals who have serious heart rhythm issues starting in the lower chambers of the heart.
To work effectively, Disopyramide must be taken consistently at the exact times prescribed by your doctor, usually multiple times throughout the day. You can take this medicine with or without food, but it is best to choose one way and stick to it with every dose to maintain stable levels in your body. Your doctor may also suggest certain lifestyle changes, such as limiting caffeine and getting regular, gentle exercise, to support your heart health.
Some people taking Disopyramide may experience side effects like dry mouth, blurred vision, constipation, or difficulty urinating. While these are usually mild, you must consult your doctor immediately if you face serious issues such as sudden shortness of breath, unexplained swelling in your legs, or chest pain.
Before starting Disopyramide, tell your doctor about your complete medical history, especially if you have glaucoma, liver damage, kidney issues, or myasthenia gravis. Do not take this if you have certain severe heart conditions, such as cardiogenic shock or specific types of heart block, unless you have a working pacemaker.
This medication can interact with other substances, including alcohol, which can worsen dizziness and lower your blood pressure dangerously. If you are pregnant, breastfeeding, or an older adult, you should consult your doctor or pharmacist to discuss the risks and benefits before starting this treatment.

Patients Concern
Disease/Condition Glossary
Arrhythmias: Arrhythmias (irregular heartbeat) is a condition in which your heart beats abnormally, too fast, or too slow. Symptoms of irregular heartbeat include chest pain, shortness of breath, and fast or slow heartbeat. 60 to 100 beats per minute is generally considered a normal heart rate. Pulse indicates your heart rate or the number of times your heart beats in a minute. Normally, the pulse rate increases when you exercise and is slower when you are at rest. Tachycardia is when the heart beats faster than normal, and bradycardia is when the heart beats too slowly. Atrial fibrillation is the most common type of arrhythmia, which causes an irregular and fast heartbeat. Your doctor may run certain tests to diagnose if you have an arrhythmia. Treatment to restore a normal heart rhythm may include medicines like Disopyramide, an implantable cardioverter-defibrillator (ICD), a pacemaker, or surgery.
FAQs
Disopyramide is used to treat arrhythmia (irregular heartbeats). It helps slow the heart rate and prevent abnormal heart rhythms.
Disopyramide contains disopyramide that works by blocking abnormal electrical signals in the heart. Thus Disopyramide helps to treat uneven heartbeats and helps in normalizing the heart rhythm.
No, you are not recommended to take amiodarone with Disopyramide as co-administration of these two medicines may increase the levels of Disopyramide in the blood resulting in Disopyramide toxicity. However, please consult a doctor before taking other medicines with Disopyramide to adjust the dose appropriately.
Do not stop using Disopyramide even if you feel better. It should be strictly used as advised by your doctor to avoid recurring symptoms like irregular heartbeat and to worsen the disease.
Disopyramide should be used with caution in cases of any allergic reactions, heart problems like heart failure, slow heartbeat, QT prolongation (heart muscle takes longer than usual to recharge between beats) in the ECG (electrocardiogram), and electrolyte imbalance (low levels of potassium and magnesium).
Store Disopyramide away from direct sunlight and at a temperature not exceeding 30°C. Keep this medicine out of sight and reach of children.
If you missed a dose, take Disopyramide as soon as possible. However, if it is time for the next dose, skip the missed dose and go back to your regular dosing schedule. Do not double the dose.
Yes, Disopyramide may cause dry mouth as a temporary side effect in some people. It is not necessary for everyone taking Disopyramide to experience this side effect. However, to avoid such side effects, drink plenty of water, regularly rinse your mouth, practice good oral hygiene and suck on sugarless candy. However, if the condition persists or worsens, please consult a doctor.
It is highly recommended to avoid alcohol while taking Disopyramide. Alcohol can increase the risk of side effects like dizziness and lightheadedness, and it can also directly interfere with your heart's rhythm. Talk to your doctor for personalised advice.
Dry mouth is a very common side effect. You can manage this by sucking on sugarless hard candies, chewing sugarless gum, or sipping water frequently. If the dry mouth becomes severe or does not go away, talk to your doctor or pharmacist.
You should only take Disopyramide during pregnancy or breastfeeding if your doctor determines that the benefits outweigh the potential risks to your baby. If you are pregnant or planning to become pregnant, talk to your doctor right away.
Yes, in some cases, Disopyramide can cause low blood sugar (hypoglycemia), especially in older adults or people with liver or kidney issues. If you experience shakiness, sweating, or confusion, check your blood sugar if possible and talk to your doctor.
Some blood pressure medicines, especially those that also slow your heart rate, can interact with Disopyramide. Before starting this medicine, make sure your doctor knows about all other prescriptions you are taking. Talk to your doctor or pharmacist to perform a safety check.
Yes, Disopyramide can cause blurred vision or difficulty focusing your eyes. Be very cautious when driving or doing tasks that require clear vision until you know how this medicine affects you. If your vision changes do not improve, talk to your doctor.
No, you must swallow Disopyramide capsules whole. Crushing, chewing, or opening the capsules can cause the medication to release too quickly into your body, increasing the risk of side effects. If you have trouble swallowing capsules, talk to your doctor or pharmacist for alternative options.
