A prospective survey of pharmacists’ tasks and patients’ knowledge and satisfaction was conducted in 35 randomly selected community pharmacies in Tabriz, Islamic Republic of Iran. The total pharmacist interaction received a mean score of 3.05 out of 5. Providing written directions for use attained the highest score of 0.98 out of 1. Patients scored 3.18 out of 5 for knowledge about their medicines. There was a close correlation between patients’ knowledge of dispensed drugs and pharmacist interaction (r = 0.95). Mean total prescription filling time was 7.6 min, but only 1.4 min was spent on pharmacist–patient counselling. The interaction between pharmacist and patient increases patients’ knowledge about dispensed medicines and their satisfaction with the pharmacist’s activities.
