The Food and Drug Administration said it will not fight a judge's ruling opening access to the "morning after" pill.
The decision means 17-year-olds will be able to buy the emergency contraceptive over the counter without a prescription.
The tiny pill already has a history of controversy, and Planned Parenthood of North Texas said it was pleased to hear the news.
"We would just like for young people to be armed with all the tools possible so they don't find themselves with an unintended pregnancy that could potentially hijack their futures," spokeswoman Kelly Hart said.
"If something, like, she'd ever want to have that while she was underage, I'd want to be aware of that and be able to help her and support her," she said.
Scott Davis, a father of a 17-month-year old girl agreed. He said he was worried the regulation could easily sideline a parent from what could be a very important conversation with their teenager.
"Hopefully she's not in that situation, but if she was, I would definitely want to know about that," he said. "I think you should probably be talking about that anyway, but this adds another layer to it."
The same U.S. district judge in New York who ordered the FDA to allow 17-year-olds to get the Plan B pill over the counter also ordered the agency to look into whether all age restrictions should be lifted.
