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 confirmed Thursday it has no plans to start dispensing mifepristone, also known as the abortion pill, as it says it hasn’t seen demand for it. Conservative groups claim they deserve credit for keeping the medication out of their stores.
