The Plan B morning after pill can sit on store counters next to other products, without requiring a prescription or parental consent for any teen age 15 and up.
The FDA has made the decision Tuesday after a federal judge in New York ruled The Plan B pill should be available to all ages without a prescription earlier this month.
The FDA’s decision to lower the age to 15 comes just days before the court's deadline.
A teen must prove they are at least 15 years old at the cash register when making the purchase.
If taken within 3 days of contraception, the pill can prevent pregnancy at a rate of almost 90 percent.
Despite the federal court ruling, the FDA says their decision was "independent of the court case".
