Article points out: "Some other drugs that NHS England is proposing to restrict, such as liothyronine, have limited evidence for their benefits, but some patients do find them useful, and patients and some clinicians will express resistance to the proposed restrictions on their use."
It appears that CCGs do not have the authority to tell GPs what not to prescribe. Individual GPs, not CCGs, could be found in breach of the General Medical Services contract if they do not prescribe treatment patients have been told "they need". I would encourage anyone who has had their Liothyronine prescription withdrawn due to CCG 'instruction' to report their GP to the GMC unless it is reinstated.
The article also says: "NHS England also needs to make the necessary changes to the National General Practice Contract and to the NHS Drugs Tariff, to ensure that any prescribing restrictions it imposes have a firm legal basis. If this is not done, it places GPs in the invidious position of being at clinical and legal risk if they adopt NHS England’s prescribing guidance when this is finally published, at a time when they are already under considerable workload pressure.89"
