Mitch Winehouse tells Anderson Cooper she took a drug to treat alcohol withdrawal.
Amy Winehouse's father admits that there was one drug in her blood when she died—but he insists that she had a prescription for it.
In an interview on Anderson Cooper's new talk show, which airs Monday, Mitch Winehouse says his late daughter was taking a drug called Librium, which is used to treat acute alcohol withdrawal.
Mitch tells Cooper she had a dose-a-day prescription for it, to help prevent withdrawal-related seizures. But he believes that it didn't work as advertised, saying that he thinks the singer died from an alcohol detox seizure. "There was nobody there to rescue her," he adds.
Mitch again adamantly denies that there were illegal drugs in Amy's system when she died. "We really felt we were out of the woods," he says. "We saw the light at the end of the tunnel."
