Can amiodarone affect your thyroid?

Why is amiodarone contraindicated in thyroid disease?
Amiodarone can lead to inhibition of T4 and T3 entry into the peripheral tissues. Both amiodarone and its principle metabolite may have direct cytotoxic effects on the thyroid follicular cells, leading to a destructive thyroiditis [Bogazzi et al.
Does amiodarone cause photosensitivity?

Can amiodarone cause thyroid storm?
Amiodarone-induced thyrotoxicosis was the most common cause of thyroid storm (33%), followed by Graves’ disease (26%). Autoimmune thyroiditis, toxic multinodular goiter, and toxic solitary thyroid adenoma were much less frequent causes (10%, 9%, and 6% respectively).
Does levothyroxine interact with amiodarone?

How is amiodarone induced hyperthyroidism treated?
Mild AIT may spontaneously resolve in about 20% of the cases. Type 1 AIT should be treated with high doses of thioamides (20-60 mg/day of methimazole; or 400-600 mg/day of propylthiouracil) to block the synthesis of thyroid hormones (Figure 1).
Can you take amiodarone with thyroid medication?
Amiodarone may inhibit the peripheral de-iodination of T4 to T3 resulting in a decreased concentration of active hormone, which can cause more overt symptoms in patients with existing hypothyroidism Amiodarone is therefore contraindicated in patients with current or previous thyroid dysfunction.
