Dispensing and Variabilities in Pricing of Headache OTC Medicines by Community Pharmacies in a German Big City: A Simulated Patient Approach.

Background: In Germany, over-the-counter (OTC) medicines for self-medication may only be dispensed by community pharmacies (CPs). From the customer's point of view, "adequate" counseling includes not only the recommendation of medicines that meet guidelines, but also the dispensing of low-priced medicines. This is all the more important in Germany against the background of free pricing and a lack of obligation to display prices. The aim was to analyze the dispensing and possible price variability of OTC medicines for headache. Methods: The cross-sectional design of the study based on the simulated patient methodology (SPM) included all 42 CPs of the German big city Potsdam and used eight trained simulated patients (SPs). Between October and December 2020, four different SPs visited each CP four times with two almost identical scenarios with the demand for a medicine for headache. Results: All 168 planned visits were successfully completed and ibuprofen (60.1%) was dispensed most frequently. Across all dispensed medicines, prices varied from €0.93 to €9.97 (∆ 972%; median €3.46 [interquartile range (IQR) €2.25]). For repeated dispensing of the same CPs, the price variability was a maximum of €8.77. In addition, packs with ≤10 tablets were dispensed in 47.6%, with 11 to 20 tablets in 50.6%, and with >20 tablets in 1.8% of visits. Conclusion: Increasing price transparency and strengthening price competition could make it easier for customers to access OTC medicines according to their personal needs.
