POTENTIAL IMPACT

The practical consequences of a ruling for abortion opponents would be dramatic, including possibly halting the delivery of mifepristone through the mail and at large pharmacy chains, and ending increasingly popular telehealth visits at which the drug can be prescribed.

President Joe Biden’s administration and drug manufacturers warn that such an outcome also could undermine the FDA’s drug approval process more widely by inviting judges to second-guess the agency’s scientific judgments. The Democratic administration and New York-based Danco Laboratories, which makes mifepristone, say that the drug is among the safest the FDA has ever approved.
