Answer

Patients with severe hypothyroidism requiring hospitalization (eg, myxedema) may require aggressive management. Overreplacement or aggressive replacement with any thyroid hormone may precipitate tachyarrhythmias or, very rarely, thyroid storm and should be balanced against the need for urgent replacement. Risk is higher with T3 therapy.
