Triostat (liothyronine sodium injection) (T3) is a thyroid hormone preparation indicated in the treatment of myxedema coma/precoma. Triostat can be used in patients allergic to desiccated thyroid or thyroid extract derived from pork or beef. Triostat is available in generic form. Common side effects of Triostat include:

An initial intravenous Triostat dose ranging from 25 mcg to 50 mcg is recommended in the emergency treatment of myxedema coma/precoma in adults. Triostat may interact with oral anticoagulants, insulin or oral hypoglycemics, estrogen, oral contraceptives, tricyclic antidepressants, digitalis, ketamine, and vasopressors. Tell your doctor all medications and supplements you use. Tell your doctor if you are pregnant before receiving Triostat. Thyroid hormones do not readily cross the placental barrier and in general, thyroid replacement therapy to hypothyroid women should not be discontinued during pregnancy. Minimal amounts of Triostat pass into breast milk. Thyroid hormones such as Triostat are not generally associated with serious side effects. Consult your doctor before breastfeeding.
