The Society for Endocrinology supports the British Thyroid Association position on treating underactive thyroid
The Society for Endocrinology fully supports the British Thyroid Association (BTA) Executive Committee statement on the treatment of underactive thyroid (hypothyroidism) published online on the BTA website on 8 February 2017.
In summary, the conclusion is that the benefits of combination therapy with LT-4 and LT-3 are still unproven, and the potential for harm exists with unregulated use of unapproved therapies especially the lack of long term L-T3 safety data and the unavailability of L-T3 formulations which accurately mimic natural physiology.
The BTA statement has also been endorsed by the Association of Clinical Biochemistry (ACB); the British Thyroid Foundation (BTF); the Royal College of Physicians (RCP).
