Question to the Department of Health and Social Care:

To ask Her Majesty's Government what action they propose to take in relation to thyroid patients who, having previously had successful treatment on dosages of 20mcg and above of liothyronine, are now facing a restriction on the dosage.

Whilst NHS England and NHS Improvement will regularly review its guidance, at present, there are no plans to revisit the specific recommendations for liothyronine unless new clinical evidence comes to light. Decisions on appropriate treatment for thyroid patients and doses are taken in accordance with a clinical management plan and implemented by the clinician.
