Both liver and thyroid function studies improve following treatment for hyperthyroidism. Total T4 (reference range 4.5–12.5 μg/mL), free T4 (reference range 0.89–1.80 ng/dL), total bilirubin (reference range 0.2–1.2 mg/dL), alkaline phosphatase (reference range 38–126 U/L), total T3 (reference range 0.6–1.71 ng/dL), T3 uptake (reference range 0.90–1.30 TBI) AST (reference range 8–60 U/L), ALT (reference range 14–78 U/L) levels measured over hospital course during therapy with propylthiouracil (PTU; orange), methimazole (MMI; blue), corticosteroids (dexamethasone; green), and potassium iodide (SSKI; purple). PTU 400 mg q6 h, dexamethasone, and SSKI 4 drops q6 h were started on the end of day 2 of hospitalization. Dexamethasone was discontinued and PTU was reduced to 200 mg q8 h on day 9. SSKI was reduced to 2 drops q8 h on day 12. PTU was discontinued and MMI 40 mg daily was initiated on day 13. MMI and SSKI were discontinued on days 16 and 18, respectively. PTU was then restarted at 200 mg q8 h on day 25 and maintained at 150 mg q8 h after day 37 of hospitalization
