Evaluation of instructions in patient information leaflets for the use of intranasal corticosteroid sprays: an observational study.

ABSTRACT

OBJECTIVES: In this study, we analysed patient information leaflets (PILs) of intranasal corticosteroid sprays (INCS) of different manufacturers in the UK to determine if instructions for the use of INCS are complete and uniform. SETTING: PILs of all INCS of all manufacturers, available for patients in the UK, were collected from the British National Formulary website and the Medicines and Healthcare products Regulatory Agency website. All instructions in these PILs were analysed. PARTICIPANTS: We identified PILs of INCS from 21 different manufacturers, available for patients in the UK. RESULTS: We analysed the instructions for the use of INCS in 21 different PILs and there is large variation in the PIL instructions for the technique of using INCS across PILs. CONCLUSION: Complete and uniform instructions for the use of INCS are lacking in PILs for registered preparations in the UK. Structured and standardised instructions to be used by both professionals and patients are essential in order to optimise daily use of INCS.
