Which combination is recommended for subacute thyroiditis?

• A. Methimazole
• B. Radioiodine therapy
• C. Levothyroxine
• D. Beta-blockers, NSAIDs, and corticosteroids

Answer: (D)

Subacute thyroiditis causes a painful, inflamed thyroid with a temporary thyrotoxic phase from release of stored thyroid hormone. Treatment focuses on relieving inflammation and controlling the symptoms of excess thyroid hormone, rather than suppressing hormone production.

NSAIDs are the first-line for pain and thyroid inflammation, helping reduce the thyroid pain and swelling. If pain and inflammation are more severe or NSAIDs aren’t enough, corticosteroids are added to provide stronger anti-inflammatory effects and rapid relief. Beta-blockers are used to counteract the adrenergic symptoms of thyrotoxicosis—like rapid heartbeat, tremor, and anxiety—without altering thyroid hormone production.

Antithyroid drugs (which block new hormone synthesis) aren’t useful here because the problem is release of preformed hormone from damaged follicles, not increased synthesis. Radioactive iodine therapy isn’t appropriate for an inflammatory, self-limited thyroiditis, and levothyroxine is reserved for treating hypothyroidism that may occur later, not for the acute thyrotoxic phase.

So the combination of beta-blockers, NSAIDs, and corticosteroids targets the key symptoms and inflammation in subacute thyroiditis, making it the best approach.
