The Supreme Court is sending back to state court a case about an Oklahoma anti-abortion law that bans off-label use of certain abortion-inducing drugs.
The justices on Thursday asked the Oklahoma Supreme Court to clarify some questions before the high court considers an appeal.
The state court threw out the law requiring doctors to follow strict guidelines authorized by the Food and Drug Administration and barring off-label uses of certain abortion-inducing drugs.
Such moves include changing a recommended dosage or prescribing it for different symptoms than the drug was initially approved for. Oklahoma judges had halted enforcement during the court challenge.
The justices asked if state law blocks the use of misoprostol, including in conjunction with mifepristone, and if it blocks the use of methotrexate in ectopic pregnancies.
