Amiodarone is a potent antiarrhythmic medicine used to treat life-threatening heart rhythm issues such as ventricular fibrillation. It works by relaxing overactive heart muscles to restore a normal heartbeat. This active ingredient is found in trusted generic alternatives that meet strict UK quality standards. Our pharmacy ensures convenient and reliable access to various medications containing Amiodarone for patients requiring heart rhythm stabilisation.
Amiodarone belongs to a class of medicines called anti-arrhythmic agents. Its main role is to help control abnormal heart rhythms. In the United Kingdom, amiodarone is found in products such as Cardarone and the generic preparation simply called amiodarone.
Patients may encounter amiodarone in several forms. The most commonly prescribed options are:
Both are oral tablets, and the same active ingredient is present in each product. The choice between a brand and a generic often depends on prescribing preferences and local pharmacy stock. In the UK, these medicines are supplied under the supervision of a qualified prescriber and are listed on the NHS formulary.
Amiodarone is used to manage several cardiac conditions where the heart’s rhythm is irregular:
These uses are approved by the Medicines and Healthcare products Regulatory Agency (MHRA). In some cases, clinicians may prescribe amiodarone for other rhythm problems based on individual assessment, but those decisions are made on a case-by-case basis.
Amiodarone helps the heart beat more regularly by influencing the electrical signals that control each heartbeat. It slows down the speed at which these signals travel, which can stop rapid or erratic rhythms and allow the heart to settle into a normal pattern. Most people notice an effect within a few days, although full stabilisation may take longer, especially when the medication is started at a lower dose and built up gradually.
People taking amiodarone-containing medicines often experience mild and temporary effects, such as:
These symptoms usually lessen as the body adjusts to the medication.
Rare but important warnings include:
If any of these appear, urgent medical evaluation is required.

Amiodarone may interact with a range of other substances. General points to remember include:
For a complete list of interacting agents, refer to the patient information leaflet that accompanies each specific product.
Amiodarone tablets should be stored in a dry place away from direct heat, ideally at room temperature. Treatment length varies: some people use the medication for a short-term course to stabilise an acute rhythm problem, while others remain on it for longer periods to prevent recurrent episodes. Because formulations and strengths differ between Cardarone and the generic amiodarone, always follow the instructions printed on the product’s label. For detailed guidance on dosing, administration, and monitoring, see the specific medication’s information sheet.
