Background: An off-label medication involves the use of an approved drug for an unapproved indication, population, route of administration, or dosage.The physiological state of children differs from that of adults, making the adult formulation potentially dangerous to children. Off-label prescribing is quite common in children due to challenges in the development of pediatric formulations. The current study was conducted to determine the awareness, practice, and views of pediatricians, general physicians, and pharmacists about prescribing Off-label medication to pediatric patients in Eastern Province, Saudi Arabia. Methods: A cross-sectional study based on a questionnaire was conducted among pediatricians, general physicians, and pharmacists (clinical and community) in Eastern Province, Saudi Arabia. Statistical analysis was conducted using the data exported from Google Forms (Mountain View, California, USA) and Microsoft Excel (Version 2016) and then exported into Statistical Package for Social Sciences (SPSS) version 26.0 (IBM, Inc., Armonk, NY, USA). Chi-square was deemed suitable. The level of significance was set at 0.05. Results: Among the study participants, 53(35.09%) were pharmacists, followed by 24(15.89%) others, 22(14.565) pediatricians, 19(12.58%) other specialists, 17(11.25%) general physicians, and 16(10.59%) were clinical pharmacist.

Further, 97(64.23%) considered themselves not enough knowledgeable about off-label medications. The barriers reported by the participants were as follows: 89(58.945%) said lack of information resources, 71(47.01%) said lack of training, 56(37.08%) said lack of information on the safety of excipients used in pediatrics, 47(31.12%) said lack of formulary, 44(29.13%) said lack of guidelines, and 58(5.29%) said lack of information related to the safety of excipient concentration in pediatrics. The proportion of healthcare professionals who agreed that excipients in adult medication may be harmful to pediatrics was 103(68.21%). The drugs most often prescribed as off-label were paracetamol 54(21.68%), followed by Phenobarbital 35(14%), and Amoxicillin 33(13.25%). Conclusion: There are a considerable number of healthcare professionals unaware of the description of off-label medication. The majority have concerns over the safety and efficacy of the off-label drugs and believe that most frequently used off-label drugs in pediatrics must be tested in pediatrics during clinical trials. In addition, excipient safety data are of considerable importance to ensure off-label drug safety in pediatrics, who believe their knowledge is inadequate and need proper guidelines and training on this issue. result: Among the study participants, 5335.09% were pharmacists, followed by 2415.89% others, 2214.565 pediatricians, 1912.58% other specialists, 1711.255 general physicians, and 1610.59% were clinical pharmacist.7348.345 described the definition of off-label correctly.11475.495 believe that parents and guardians must be informed about off-label medicine prescribed to their children. 5234.43% had concerns about the safety of the medication and 9864.90% believed they should be tested in paediatrics during clinical trials.9764.23% consider themselves not enough knowledgeable about off-label medications.
