WORCESTERSHIRE DRUG FORMULARY UPDATED – includes APC decisions to February 2010 This Formulary is for use across Worcestershire, both in primary and secondary care. Originating in the Acute Trust, it is now maintained by the Worcestershire Area Prescribing Committee (APC). It is updated following monthly APC meetings and will be regularly reviewed to ensure that the medicines listed are evidence-based and take into consideration recommendations from NICE, MTRAC and APC. Prescribing of medicines within the Acute Trust must be in line with the ‘Strategy for Medicines Use’ in the Acute Trust Medicines Policy. Where it is specified that an APC guideline must be followed these may be found at: http://www.worcspct.nhs.uk/publications/policies-and-procedures/prescribing.aspx Notes for Acute Trust Users: Initiating a new treatment for a patient Trust staff may only initiate treatment with medicines included in the Trust Formulary and Trust staff must comply with any special conditions of use or restrictions noted in the formulary against the medicines. In emergency situations a Consultant may wish to prescribe a medicine that is not on the formulary. In such circumstances an attempt must be made to contact the Director of Pharmacy who may authorise pharmacy to obtain and supply the medicine. If this is not possible a senior pharmacist may obtain and supply the medicine without authorisation but a retrospective approval must be obtained by following the Trust High Cost Drug Procedure (see Intranet under Clinical departments\Pharmacy). No precedent for further supplies will be set. If a patient admitted to the Trust is already being treated with a drug not included on the Trust formulary, the patient’s own supply will be used wherever possible. In such circumstances, members of medical, nursing and pharmaceutical staff have responsibility for confirming the authenticity of the medicine. Requests for Drugs to be Included in the Formulary Consultants only may make applications to the APC for additions to the formulary. These must be made on a standard request form available from the Medicines Information Departments at the Alexandra or Worcester Hospitals. Junior Doctor Prescribing Junior Doctors wishing to prescribe drugs they are unfamiliar with would normally be expected to seek the advice of their Consultant.
