Sample item

Which adverse effect is characteristic of amiodarone therapy?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Thyroid dysfunction

Amiodarone contains iodine and has complex tissue accumulation, so it can cause hypothyroidism or hyperthyroidism as well as lung and liver toxicity.

Option by option

  • A. Thyroid dysfunction (correct)

    Correct: thyroid dysfunction is a recognised amiodarone effect.

  • B. Hair loss from folate deficiency

    Folate deficiency is not the mechanism.

  • C. Severe hypoglycaemia only

    Hypoglycaemia is not its defining toxicity.

  • D. Immediate renal stone formation

    Renal stones are not typical.
