Formulary

Note: Liothyronine 20mg tablets should only be prescribed as per the following guidance:

  • In line with British Thyroid Association (BTA) guidance, where levothyoroxine has failed, liothyronine may be recommended for individual patients after a carefully audited trial of at least 3 months duration of liothyronine.
  • Existing patients should be reveiwed, as appropriate, by an endocrinologist to ensure the continuing need for liothyronine. Patients shouldn't have treatment stopped without review by an endocrinologist.
