The science of veterinary medicine is currently lacking studies on medication safety, although its importance in protecting animals from medication errors is central. Pharmacy professionals have an important role in ensuring medication safety of both prescription and over-the-counter medications of animals. However, this requires adequate competencies of pharmacy professionals in veterinary pharmacotherapy. The present study aimed to explore the competencies of pharmaceutical staff in community pharmacies in veterinary pharmacotherapy, which factors influence these competencies and what kind of information sources they typically use on veterinary pharmacotherapy.The study was conducted as a cross-sectional online survey targeted to pharmacy professionals in the Finnish community pharmacies, providing 596 responses. Less than half of the respondents (41%, n = 246) are considered to possess good competencies in veterinary pharmacotherapy. A third of the respondents (35%, n = 211) would dispense an anti-inflammatory drug for an animal off-label, whereas 24% (n = 145) would not interview the pet owner to discover the need for internal parasite medication before dispensing the drug. A small proportion (<1%, n = 5) would have dispensed a broad-spectrum internal parasite medication. Approximately a quarter of the respondents (27%, n = 159) stated that they acquired information on pharmacotherapy only from the material produced by the manufacturers of veterinary drugs.The competencies of pharmacy professionals in veterinary pharmacotherapy need to be strengthened in many areas to better promote veterinary medication safety. It should also be ensured that pharmacy professionals can access and use independent, high-quality information on veterinary pharmacotherapy.
