Important safety information and potential risks associated with the drug.

Warnings and Precautions

Key precautions include the risk of THYROGEN-induced hyperthyroidism in patients with significant residual thyroid tissue, which has been associated with rare fatal outcomes. There are postmarketing reports of stroke, primarily in young women with risk factors. Sudden, rapid, and painful tumor enlargement can occur, potentially compromising vital structures. All contraindications and warnings for radioiodine also apply when THYROGEN is used in combination.
