Tertroxin (Liothyronine sodium) 

Tertroxin is a synthetic form of "liothyronine" (T3), which is a naturally occurring thyroid hormone, produced by the thyroid gland.

Levothyroxine – thyroid hormone replacement (T4) medication breaks down into Liothyronine (T3) once it absorbs after ingesting. 

Tertroxin is usually prescribed, after very careful consideration, by a thyroid treating specialist (Endocrinologist) who will determine if it will benefit the patient.  It can be prescribed to take with Levothyroxine (T4) medication or alone.  Please seek advice from an Endocrinologist who will monitor your pathology results regularly whilst taking Tertroxin.
