Perceptions and attitudes towards off-label dispensing for pediatric patients, a study of hospital based pharmacists in Jordan

BACKGROUND: With growing responsibility of the pharmacists in ensuring public health and safe medicine use, an understanding of the issues surrounding off-label prescribing is crucial to allow pharmacists to make informed decisions about such practice. The aim of this study is to assess the perceptions and attitudes of hospital based pharmacists toward off-label medicine dispensing to children. METHODS: After obtaining the required approvals, a validated questionnaire about off-label dispensing to pediatric patients was administered to 250 randomly selected hospital pharmacists. RESULTS: One hundred and fifty (150) completed questionnaires were returned. Less than half of the respondents (44%, n = 66) admitted to being familiar with the concept of off-label dispensing, claiming to have obtained this knowledge basically through their dispensing experience rather than education. A minority of respondents (36%, n = 54) reported dispensing off-label medicines within their practice knowingly. The majority of respondents had concerns regarding the efficacy (82%, n = 123) and safety (98%, n = 147) of off-label medicines. The most common reasons given by respondents for a dispensed prescription being off label were younger age than recommended (88%, n = 132). Most of respondents (94%, n = 141) claimed to double check the calculations of doses of medicines before dispensing off-label medicines and 60% (n = 90) of them felt that parents and guardians should be told when an off-label medicine has been prescribed for their children. CONCLUSION: The majority of respondents were not familiar with the concept of offlabel medicines. While reporting to have gained their knowledge from their professional experience, only a minority of respondents reported knowingly dispensing off-label medicines for pediatric patients. Respondents indicated that manufacturing more appropriate formulations for pediatric patients would reduce such practices in this population. Having concerns regarding the efficacy and safety of off-label medicines used for pediatric patients, respondents felt that the use of off-label medicines would increase the likelihood of adverse drug reactions (ADRs). Finally, respondents felt that such practice of prescribing and dispensing should receive parental consent.
