EDISON - The Food and Drug Administration is expected to announce a virtual ban of alcoholic energy drinks, even as a leading manufacturer is pulling its products off the market.

The FDA is expected to say today that caffeine is an unsafe food additive to alcoholic drinks, a move that would effectively ban them from sale.

Phusion Projects, which manufactures Four Loko, announced late yesterday that it would reformulate its drinks, removing caffeine. While there is little known medical evidence that the drinks are less safe than other alcoholic drinks, public health advocates say they can make people feel more alert and able to handle risky tasks like driving.

Last month, Ramapo College in Mahwah banned alcoholic energy drinks. The move came after nearly two dozen students were hospitalized after reportedly consuming Four Loko.
