What labs need to be monitored for patients taking amiodarone?

Monitoring for patients taking amiodarone is particularly crucial due to the drug's unique pharmacologic properties and potential side effects. Amiodarone is associated with various organ system toxicities, and regular assessment helps to mitigate risks and manage any emerging complications effectively.

Thyroid function tests are essential since amiodarone contains iodine and can either induce hypothyroidism or hyperthyroidism, leading to significant metabolic disturbances. Additionally, liver function tests are important because amiodarone can cause hepatotoxicity, and regular monitoring ensures that any liver-related side effects are identified early. Lung function testing is necessary as well, as amiodarone is known to potentially cause pulmonary toxicity, including pulmonary fibrosis.

While other laboratory tests could be relevant for specific situations—like electrolytes for the risk of arrhythmias or cardiac enzyme levels in instances of suspected acute coronary syndrome—they do not address the specific toxicities associated with amiodarone therapy. Therefore, the focus on thyroid, liver, and lung function tests is vital for the safe use of this medication.
