  ABSTRACT: Background: Hospital formularies are used to encourage the use of safe, ef-fective and most affordable medications. Institutions need to make provi-sions for non-formulary medicines (NFM) due to the dynamic nature of dis-eases and their management. The aim of this study was to describe the pat-terns of non-formulary medicine prescriptions at the Nairobi Hospital, the reasons for their purchase as well as the duration taken to avail them. Methods: A descriptive review of all the non-formulary medicine prescrip-tions from January 2021 to June 2022. The medicines were listed and catego-rized according to the WHO Anatomical Therapeutic Chemical (ATC) classi-fication system. Correspondence between pharmacy and procurement was reviewed to understand the reason for the requests and the duration it took to avail the medicines. Results: A total of 183 NFM were purchased, with a general increase in the number from January 2021 to June 2022. Vitamins, Mineral supplements and General nutrients accounted for 41 (22.4%) of the NFM. Dermatologicals 27 (14.6%), Genito-urinary system drugs and sex hormones 20 (10.9%), Ophthalmologicals 14 (7.6%) and Antineoplastic and Immuno-modulating agents 12 (6.6%) were also frequently purchased out of formulary. The main reasons for NFM purchases were: having no therapeutic equivalents in the hospital formulary 72 (39.3%) and prescriber or patient preference 69 (37.7%). It took a median (IQR) of 4 (2 - 7) days for the phar-macy to avail these drugs; with 18.6% being availed in 1 day and 55.2% tak-ing more than 3 days. For the NFM where no alternative was available in the hospital formulary, sales amounted to USD 63,362 which was 79.1% of the value of all the NFM sales. Conclusion: There’s a need to regularly update the hospital formulary and to emphasize to the prescribers the importance of adhering to it, as much as possible.
