See main article: Triiodothyronine (T3) Levothyroxine should only ever be prescribed in micrograms (mcg) to reduce the risk of prescription error. Common calculation errors when converting from mcg to mg (e.g. - 0.025mg to 25mcg (correct), may sometimes be mistakenly converted to 250mcg (a 10-fold dose increase error). text/html 2021-12-27T15:06:43-0700 Anonymous (anonymous@undisclosed.example.com) https://www.psychdb.com/meds/thyroid/triiodothyronine-t3?rev=1640646403&do=diff Triiodothyronine (T3) Primer Triiodothyronine (T3) (also known as liothyronine) is the active form of the thyroid hormone, thyroxine. Approximately 20% of T3 is secreted into the bloodstream directly by the thyroid gland. The remaining 80% is produced from conversion of thyroxine by organs such as the liver and kidneys. In psychiatry, liothyronine is sometimes used as an augmentation medication for depression in combination with antidepressants.
