Counselling with a focus on product and price transparency for over-the-counter headache medicines: A simulated patient study in community pharmacies in Munich, Germany.

Background: In Germany, over-the-counter (OTC) medicines may only be dispensed by community pharmacies (CPs). German CPs must ensure 'adequate' counselling, including the cost of medicines. Along with information gathering and advice giving as classic aspects of counselling, the aim was also to investigate counselling indicators of product and price transparency.
