Objectives: Probiotics have been gaining increased attention from the public recently, which originates concerns about their rationale use among healthcare professionals. Although there is evidence on the efficacy and safety of probiotics in certain gastrointestinal disorders, it is important to identify healthcare professionals' opinions on probiotics. This study aimed to identify the opinions of pharmacists and physicians on the use of probiotics.

Materials and methods: This cross-sectional study was conducted between November, 2017 and August, 2018 among pharmacists and physicians practicing in Ankara, Türkiye. An electronic survey was designed and sent to the participants via e-mail.

Results: A total of 361 pharmacists (74.5% female) and 356 physicians (42.4% female) participated in the study. Approximately two-thirds of pharmacists and physicians were familiar with the mechanism of action and indications of probiotics. Most pharmacists and physicians recommended probiotics to be used in gastrointestinal system disorders (99.7% and 97.7%). Other areas that probiotics are commonly recommended was genitourinary system (29.3%) by pharmacists and dermatological symptoms (15.1%) by phycisians, respectively. Considering patient advice regarding the probiotics, pharmacists (63.3%) seemed to receive more requests compared to physicians (30.9%); and with regard to the probiotic recommendation, 70.7% and 38.2% of pharmacists and physicians, respectively, indicated that they have no concerns, but 61% of physicians have concerns on reimbursement policy when prescribing.

Conclusion: Pharmacists and physicians are healthcare providers commonly asked about probiotics by patients. Therefore, it is important to address healthcare professionals' concerns and increase their knowledge of the use of probiotics for different health conditions. Given that probiotic products can be purchased without a prescription, healthcare professionals in primary care settings should be more vigilant about the rational use of probiotics.
