Mischa Barton Hospitalized

Mischa Barton was rushed to the hospital after suffering a reaction to medication at a friend's Memorial Day BBQ. Mischa had been drinking alcohol which reacted with antibiotics she had been taking for Bronchitis.

The 21-year-old celeb was rushed to an undisclosed medical facility in Los Angeles, where we are told she is "resting comfortably" ... the starlet is with family and "feeling much better."

I guess when your Mischa Barton it's kind of hard to fit antibiotics into your schedule between puffs of weed & cigarettes and swigs of Bacardi 151.
