Health insurer Humana (HUM) - Get Report is attempting to stop a subpoena from the Federal Trade Commission linked to the agency's review of Walgreens Boots Alliance's (WBA) - Get Report 2015 $7 billion purchase of Rite Aid (RAD) - Get Report , according to Axios

The FTC is demanding the D.C. district court force Humana to give up the documents the agency is seeking by June 26. But, Walgreens and Rite Aid agreed to certain divestitures and legally can finish the deal by July 7.

"Time is of the essence," the FTC said. "Any delay in the resolution of this petition may force the FTC to assess the competitive effects of the transaction with information that is less than comprehensive or to take extraordinary steps to address the merger after it is complete, at which point the prospect of effective relief is far more difficult."

The FTC is concerned that the Walgreens and Rite Aid deal would result in higher drug prices for consumers as Walgreens would own a lot more negotiating power over insurers and employers.

The agency is trying to deduce whether Humana's Medicare prescription drug plans, which uses Walmart (WMT) - Get Report as the preferred in-network pharmacy, would be a viable plan while exuding the combined Walgreens-Rite Aid company.

Humana is pushing back against the FTC, arguing the subpoena is irrelevant, costly and "unduly burdensome."

Humana shares fell 0.5% to $234.58 on Wednesday morning.
