Rectal thionamide administration in the setting of thyroid storm: a case report and review of the literature.

Thyroid storm is a clinical diagnosis for which urgent recognition is required to prevent untoward mortality. Treatment for thyroid storm requires prompt administration of thionamides, iodine, corticosteroids, and beta-blockers. In extreme circumstances, treatment considerations include plasmapheresis and thyroidectomy. Infrequently, patients with a thyroid storm may not be able to tolerate oral medications, for which alternative routes of access are required. Currently, available alternatives include intravenous methimazole (in Europe and Japan), as well as both enema and suppository preparations of propylthiouracil and methimazole.
