This document provides guidance on conducting prescription audits or RCPAs for retail chemists. It emphasizes the importance of identifying customer preferences and prescription habits. RCPAs should be done when chemists are free and information recorded each time to build a customer profile. The representative should introduce themselves with a smile, ask about brand availability, non-moving products, and competitors. Details should be recorded each visit to develop rapport and discuss promoted products. The goal is to understand the chemist and customers to better market appropriate products.
