Amiodarone is a medication primarily used to treat certain types of serious irregular heartbeats, known as arrhythmias. It works by affecting the electrical signals in the heart, helping to restore a normal rhythm. This drug is often prescribed for patients who have not responded well to other treatments. While Amiodarone can be effective, it may also cause side effects, including potential impacts on the lungs, liver, and thyroid. Regular monitoring by a healthcare provider is essential to manage these risks and ensure the medication is working as intended.
