The Centers for Disease Control and Prevention has said it plans to shut off the life-saving Horizon drug for about 200,000 people on Nov. 15.
The FDA said it would take a series of steps over the next several days to close the pharmacy at the end of November.
But, the agency said, the next steps are not clear.
In a statement, FDA Commissioner Dr. Nancy Brown said the agency has “no timetable for closing the business” at Horizon, which has been operating since December.
The agency has said the drug, used to treat hepatitis C, can be used for up to 18 months and is the only drug approved for that purpose by the Food and Drug Administration.
The plan to close Horizon is not the only one the agency is considering.
The Department of Health and Human Services is also considering shutting down Horizon and other specialty drug stores in the United States, and a temporary extension of its temporary suspension of the drug until the end, which is slated to expire at the beginning of December.
