Final Answer:
Liver function tests (LFTs) should be monitored regularly after starting amiodarone, with the first assessment performed within the initial few months, followed by periodic checks throughout treatment to detect potential hepatotoxicity.
Step-by-step explanation:
Amiodarone, an antiarrhythmic medication, can be associated with hepatotoxicity. Therefore, monitoring liver function is crucial. The initial LFTs should be conducted within the first few months of starting amiodarone to establish a baseline and identify early signs of liver dysfunction. Subsequent assessments should occur periodically throughout the course of treatment. Close monitoring allows healthcare providers to intervene promptly if liver function abnormalities are detected, ensuring patient safety and the continuation of effective arrhythmia management.
