Disopyramide is used to treat a condition called Hypertrophic Cardiomyopathy (HCM), which is thickening of the heart muscle. This results in obstruction to blood flowing out of the heart, which may cause breathlessness and chest discomfort during exertion.
Disopyramide slows the heart rate and makes the heart contract less forcefully, which helps reduce obstruction of blood flow in the heart in patients with HCM. This may help to improve symptoms such as breathlessness and chest discomfort. It is usually combined with other heart medications such as a beta- blocker (e.g. Bisoprolol, Atenolol) or a calcium channel- blocker (e.g. Diltiazem, Verapamil).
Common side effects include dry mouth and eyes, blurred vision, constipation and difficulty passing urine. Patients may also experience headache, sensation of fast heartbeat, dizziness and abdominal bloating. If you experience any of these, inform your Cardiologist in-charge who has prescribed this medication for you.
Disopyramide may affect the heart rhythm, namely the QT-interval which is monitored using an electrocardiogram (ECG). To reduce the likelihood of a severely abnormal heart rhythm, patients should avoid other medications which also prolong the QT-interval.
These include:
Disopyramide is available as a 100mg capsule. Follow the dosing instructions given by your Cardiologist. Take this medication before food, on an empty stomach.
You are strongly advised to inform the Cardiologist/Doctor or Pharmacist that you are taking Disopyramide, so that they can ensure that your combination of medications is safe for you.
