Class of 2011 Abstract / OBJECTIVES: To quantify and explore the trends of medications which are left unclaimed in community pharmacies. METHODS: Walgreens’ pharmacies have a process that prints off a list of all prescriptions that are left unclaimed for a period of 10 days. The paperwork accounting for the medications unclaimed between the dates of September 1, 2010 through September 30, 2010 were analyzed from two Tucson Walgreens’ pharmacies. Medications were grouped into one of fifteen categories (i.e. anti-lipids, anti-hypertensives, etc) and once data collection was completed total number of prescriptions for each category was determined. Data was then compared between the two pharmacies. RESULTS: A total of 907 prescriptions were accounted for during the 30-day period with anti-psychotics and anti-hypertensive medications being the most common prescriptions left unclaimed in both pharmacies. CONCLUSION: Pharmacists need to make a large effort to stress patient compliance on all medications, with even greater emphasis on those medications that tend to be left unclaimed more often than others.
