Amiodarone
Amiodarone is an antiarrhythmic used for selected serious Arrhythmia when its expected benefit outweighs substantial organ and interaction risks. Its effects and interactions can persist after treatment stops.
Key points
- Amiodarone affects several cardiac ion channels and can control selected atrial or ventricular rhythm disorders.
- Heart rhythm, lungs, thyroid, liver, eyes and interacting medicines may need baseline and follow-up review.
- New breathlessness, persistent cough, fainting, jaundice or major vision change requires prompt medical assessment.
Listings are for comparison and general information, not an arrhythmia recommendation; suitability and supply depend on cardiology, clinician and pharmacy checks, monitoring and prescription requirements.
How amiodarone works
Amiodarone prolongs cardiac electrical recovery and also affects sodium and calcium channels and adrenergic activity. These combined actions can stabilise some abnormal rhythms but may also slow the heart or create a different rhythm problem.
Important safety checks
Clinicians may use an ECG, chest or lung assessment, thyroid and liver tests and an eye review according to symptoms and treatment duration. Amiodarone interacts with several anticoagulants, statins, digoxin, other rhythm medicines and many additional products. Sun protection may be advised because photosensitivity is common.
When to seek urgent care
Seek urgent help for fainting, chest pain, a very slow or irregular pulse, severe breathlessness, new persistent cough, coughing blood, jaundice, severe weakness or sudden visual change. Do not stop amiodarone or another heart medicine without urgent clinical advice unless emergency services direct otherwise.
