Description |

|
All Settings
Suitable for initiation, ongoing prescribing, and discontinuation in both primary and secondary care settings. They are generally familiar, frequently used therapies that can be started within their licensed indications without specialist oversight. |

|
Specialist only Designated for initiation, ongoing prescribing, monitoring, exclusively by a specialists either in a hospital or as part of a specialist service (to note this could be in a non-hospital setting). Primary care should neither start nor continue these treatments except as part of a specialist service. A specialist could be either a medical or non-medical prescriber. |

|
Specialist advice Prescribers in primary care should seek advice and a recommendation from a specialists prior to initiating a medicine. Once agreed with a specialist, medicines can be initiated, prescribed and monitored in primary care without a formal shared-care agreement. |

|
Specialist initiation
Medicines in this category require a specialist to start therapy, titrate dosage, and assess initial efficacy or tolerability. Once stabilised, prescribing responsibility may transfer to primary care without the need for a formal shared-care agreement. |

|
Shared care agreement Prescribing responsibility can be shared across health settings and between specialists and GPs only when formal shared care arrangement has been made. For example, there may be extensive and complex monitoring requirements or significant safety concerns (note would need a national policy on this to define the criteria for requiring a formal SCA), this will be produced once nationally. |

|
Do not prescribe Not approved for routine prescribing in primary or secondary care. For example, because they are agents classified in the BNF as “not NHS” or “Drugs of Low Clinical Value”, or they are products on NICE’s “do not do” list or NHS England’s “should not routinely prescribe” list. |

|
Self Care Not for routine prescribed in primary or secondary care unless as part of care for a long term condition. Instead, patients should be encouraged to self care with support from community pharmacy. |

|
Medicines which are suitable for initiation and maintenance prescribing by primary and secondary care clinicians. These medicines should be initiated and prescribed within their licensed indications |

|
Amber Specialist Initiation: Initiation and maintenance of prescribing by Specialists and transfer to Primary Care prescribing when appropriate. This may be supported by a RICaD, annotated within the formulary entry. |

|
Amber Shared Care: Initiation and maintenance of prescribing by Specialists and transfer to Primary Care prescribing, in accordance with an ESCA, annotated within the formulary entry. |
