Disopyramide is a medication primarily used to treat certain types of irregular heartbeats, known as arrhythmias. It works by stabilizing the electrical activity in the heart, helping to restore a normal rhythm. Disopyramide belongs to a class of drugs called antiarrhythmics and is often prescribed when other treatments are ineffective. Patients taking disopyramide may experience side effects, including dry mouth, constipation, and blurred vision. It is important for individuals to discuss their medical history with a healthcare provider before starting this medication, as it may not be suitable for everyone, especially those with certain heart conditions or other health issues.
