CVS Caremark does not provide a direct option for merging two accounts. If a customer has multiple accounts, it is usually recommended to keep them separate. However, customers may want to update their account information or consolidate their prescriptions under a single account. This typically involves reaching out to CVS Caremark's customer service for assistance. They may provide options on how to manage multiple accounts more efficiently or help consolidate information as needed. Customers are encouraged to review their account details and consider making note of any necessary information they wish to retain. For specific guidance or to inquire about updates to policies, it may be beneficial to explore the appropriate section on the CVS Caremark website for the most current contact options and information.
