Patients using amiodarone should have which of the following monitored regularly?

Amiodarone is an antiarrhythmic medication that has several side effects and interactions that warrant careful monitoring of various body functions. Among these, the monitoring of liver enzymes is particularly important because amiodarone can cause hepatotoxicity. The drug affects the liver due to its metabolism and can lead to elevated liver enzymes, indicating potential liver damage or dysfunction.

Regularly checking liver enzymes allows healthcare providers to detect any early signs of liver impairment, ensuring that any necessary adjustments to the medication or additional interventions can be made in a timely manner to prevent more serious complications.

While kidney function, heart rate, and thyroid hormones are also important considerations when monitoring patients on amiodarone, the direct link between amiodarone and liver enzyme elevations highlights why monitoring liver function is critical in managing the treatment effectively.
