Insulin therapy is vital for diabetic patients, but errors in its administration can be life-threatening. Pharmacists play a key role in educating and counseling patients on proper insulin pen use. This study investigates the awareness of community pharmacists regarding insulin pen usage using a simulated patient approach. A cross-sectional study employed the simulated patient method, using a scenario with a prescription for a regular insulin pen. The focus was on evaluating pharmacists’ counseling and education roles, comparing their information with expert recommendations for optimal insulin injection techniques. The study revealed moderate performance among community pharmacists in insulin pen counseling and dispensing. Some pharmacists merely dispensed insulin and referred patients to physicians for guidance. While a high percentage demonstrated proper procedures like insulin collection, handwashing, cap removal, and insulin examination, comprehensive patient counseling was often lacking. The simulated patient study highlights the need for standardized training and ongoing education for community pharmacists in insulin pen counseling and dispensing. Many pharmacists lack the expertise to provide diabetic patients with adequate guidance, underscoring the importance of practical demonstrations and addressing geographical variations in practices.
