USA TODAY has contacted Costco for more information on the decision, but the company told Reuters that patients normally get the drug from doctors.

Kroger said it was reviewing the FDA's updated mifepristone Risk Evaluation and Mitigation Strategy (REMS) drug safety program, while CVS told Reuters that it fills "prescriptions for mifepristone in select states where legally permissible."

Costco has announced that it will not sell mifepristone abortion pills at its U.S. pharmacies, citing a lack of consumer demand. The decision follows a campaign from religious groups, including the Alliance Defending Freedom (ADF) and Inspire Investing, to persuade major retailers not to stock abortion tablets.
