CVS Health’s Caremark has reached a settlement with the Federal Trade Commission requiring notable changes to the pharmacy benefit manager’s business practices, including that Caremark prefer the lowest-cost drugs on its standard formularies and pass through savings negotiated with drugmakers to clients.

The settlement announced by the FTC on Tuesday puts to bed regulators’ allegations that Caremark preferred more expensive versions of insulin in order to increase its rebates, driving up prices for the lifesaving diabetes drug. The FTC lodged the suit against Caremark, along with fellow PBM giants Express Scripts and Optum Rx, in 2024.

Express Scripts settled with the FTC in February while Optum Rx is still finalizing an agreement with the antitrust agency.

The terms of CVS’ settlement are very similar to those secured with Express Scripts. The deal prevents the drug middleman from discriminating against cheaper drugs in its standard formularies for commercial clients, and requires it to provide a standard offering to plan sponsors that doesn’t include rebates.

It requires Caremark to include any purchases a patient makes through TrumpRx, President Donald Trump’s online drug marketplace, towards the deductible in certain health plans, once regulatory changes make that possible. The settlement also includes a number of transparency provisions.
