The document discusses the implications of the Falsified Medicines Directive (FMD) for hospital pharmacies in the UK. The FMD requires unique package numbers for all medicine packs to help identify counterfeit drugs. However, there are several operational issues with implementing this for hospital pharmacies given complexities of their supply chains. Hospitals may split drug packs, return unused stock, and source drugs through various channels. National regulations will need to address how to handle package numbers in these hospital situations to ensure successful tracking of drugs across Europe by the 2018 deadline.
