Actress Mischa Barton hospitalized briefly

Actress Mischa Barton was hospitalized for two hours after an antibiotic she was taking interacted badly with alcohol.

Barton, 21, starred on Fox network's teen drama "The O.C." Her screen credits include "The Sixth Sense," "Notting Hill" and the upcoming "Virgin Territory."

"She is fine now," said a statement from her publicist, Leslie Sloane Zelnik. The statement said Barton left Tuesday for an undisclosed overseas location to begin work on a new movie.
