ABSTRACT

This case report describes a 64-year-old male who developed subclinical hypothyroidism after three months of low-dose amiodarone (100 mg/day). Routine monitoring showed a TSH increase to 44.40 mU/L with normal FT4 and FT3 levels. Based on the Naranjo scale (score: 7), amiodarone was deemed a probable cause of SCH. This case highlights the importance of routine thyroid monitoring during amiodarone therapy, even at low doses.
Keywords: Side effects of amiodarone, amiodarone induced subclinical hypothyroidism, low dose of amiodarone, ablation, cryobaloon isolation, atrial fibrillation.
