There is no definitive answer, as the two pharmacies may be connected in various ways. However, typically CVS and Walgreens are both members of the pharmacy benefit management (PBM) network, which means that they can share data about their customers and prescriptions. This allows the pharmacies to more closely monitor and manage patients’ medications.
Additionally, the two pharmacies often offer similar services, such as flu shots and vaccinations. This means that it can be easier for patients to find the medications they need at both CVS and Walgreens.
