Seventeen-year-olds will have open access to “Plan B” emergency contraception thanks to a judge’s ruling yesterday, and access for younger teens is likely to follow.

A federal court ruled yesterday that the Bush-era Food and Drug Administration relied on politics, not science, when it limited non-prescription sales of Plan B to women aged 18 and over. The court blasted the FDA’s “political considerations … and implausible justifications” in its consideration of Plan B.

The court directed the FDA to allow 17-year-olds access to non-prescription Plan B within 30 days, and to review its decision to require prescriptions for younger teens.
