To evaluate whether medication counseling with emphasis on auxiliary labels improves recall of auxiliary label information and adherence to medication schedules.

A prospective, randomized study of an educational intervention in community pharmacies near Baltimore, Maryland. Fifty literate, English-speaking adults receiving one of the 18 commonly dispensed antibiotics were randomized to receive a counseling session or no counseling. Five to seven days after medication pickup, a structured phone interview was conducted to capture data on recall of auxiliary labels and adherence.

A total of 39 subjects completed the phone interview (78%). The rate of correct recall was high: 77% correct recall for all three labels. Among those with incorrect recall, 7 out of 9 subjects received no counseling (p = 0.11). The auxiliary labels incorrectly recalled were all related to dietary restrictions.

The findings from this study suggest that medication counseling emphasizing auxiliary label information may lead to improved recall and adherence to antibiotics. Additional studies are required to confirm the preliminary findings and determine whether they correspond to improved adherence. Information most commonly misunderstood were related to dietary restrictions. Additional research focusing on counseling related to dietary restrictions is recommended.
