What long-term monitoring is necessary for patients on Amiodarone?

Patients on Amiodarone require regular thyroid function tests as part of their long-term monitoring. Amiodarone is known to have significant effects on thyroid hormone levels due to its high iodine content and its influence on the metabolism of thyroid hormones. It can lead to both hypothyroidism and hyperthyroidism, sometimes referred to as "amiodarone-induced thyroid dysfunction."

Monitoring thyroid function allows for the timely detection and management of any alterations in thyroid hormone levels, ensuring that any necessary adjustments to the treatment regimen can be made in a proactive manner. This is particularly critical because thyroid imbalances can exacerbate cardiac issues, which is especially vital for patients with heart failure.

Other options, such as monitoring electrolyte levels, blood glucose, or cholesterol, while important in general patient care and management, are not specific to the known effects and risks associated with Amiodarone use. Regular thyroid function tests specifically address the unique side effects and complications that arise with long-term Amiodarone therapy.
