The Supreme Court says Justice Ruth Bader Ginsburg was taken to the Washington Hospital Center Wednesday evening after an apparent adverse reaction to a sleeping aid combined with cold medication she took immediately after boarding an overnight flight bound for London.
Before the plane took off, the court says, she "experienced extreme drowsiness causing her to fall from her seat. Paramedics were called and she was taken to the Washington Hospital Center as a precaution."
Justice Ginsburg was evaluated at the hospital and she was found to be in stable health.
Doctors attributed her symptoms to a reaction caused by the combination of a prescription sleeping aid and an over-the-counter cold medication.
She was admitted overnight for observation and was released this morning.
