Amiodarone (amiodarone hydrochloride) — Uses, Dosage, Side Effects & Safety
Drug class: Antiarrhythmic (Class III)
Overview
Amiodarone is a prescription medicine used to treat and prevent certain types of serious, life-threatening irregular heartbeats (arrhythmias), such as ventricular tachycardia or ventricular fibrillation. It helps restore normal heart rhythm and maintain a regular, steady heartbeat. Amiodarone works by affecting the electrical signals in the heart muscle, making it less likely for the heart to beat abnormally fast or irregularly. It is usually prescribed when other treatments have not worked or are not suitable. Key points: Amiodarone can cause serious side effects, so regular monitoring is needed. Always take it exactly as prescribed and inform your healthcare provider about any new symptoms or side effects.
