Liothyronine is a manufactured form of the thyroid hormone triiodothyronine (T3).[1] It is most commonly used to treat hypothyroidism and myxedema coma.[1] It is generally less preferred than levothyroxine.[1] It can be taken by mouth or by injection into a vein.[1]

Side effects may occur from excessive doses.[1] This may include weight loss, fever, headache, anxiety, trouble sleeping, arrythmias, and heart failure.[1] Use in pregnancy and breastfeeding is generally safe.[3][1] Regular blood tests are recommended to verify the appropriateness of the dose being taken.[1]

Liothyronine was approved for medical use in 1956.[1] It is available as a generic medication.[3] A month's supply in the United Kingdom costs the NHS about £247 as of 2019.[3] In the United States the wholesale cost of this amount is about US$22.40.[4] In 2017, it was the 252nd most commonly prescribed medication in the United States, with more than one million prescriptions.[5][6]
