The German pharmacy network acts as the crucial operational arm of the national cost-control strategy, with pharmacists having the legal obligation to perform generic substitution. When a physician prescribes an off-patent drug, the pharmacist must generally dispense the product covered by the patient's insurance Rebate Contract.

This role requires pharmacists to be experts in drug delivery forms, contract details, and, critically, patient communication. They must counsel patients on the switch, alleviating any concerns about efficacy or quality to maintain patient adherence and trust in the substituted affordable medicine.

The exceptions to this rule—such as the doctor ticking the aut idem box or the pharmacist having pharmaceutical concerns—further emphasize the professional's gatekeeping role in maintaining both cost-efficiency and clinical safety within the supply chain.
