Popis: Refractory hypothyroidism is caused by decreased gut absorption, increased metabolism, and poor compliance. Previous studies suggested that the weekly oral, suppository, or intramuscular administration of levothyroxine (LT4) is an effective treatment for refractory hypothyroidism. However, limited information is currently available on treatment involving the weekly intravenous administration of LT4. We managed a case of refractory hypothyroidism due to poor compliance, for which, by weekly intravenous LT4 administration, LT4 was intravenously administered weekly at a dose of 300 μg without any adverse effects such as acute ischemic heart diseases or liver dysfunction and effectively maintained the euthyroid status for 14 months. The weekly oral administration of LT4 (700 μg) was also safely performed and was as effective as its intravenous administration. We herein present precise clinical course of the present case including pharmacokinetic data during the weekly intravenous and oral administration of LT4 and discuss the safety and efficacy of the treatments.
