Actress Mischa Barton was rushed to the hospital late Sunday after suffering a bad reaction to medication.

The former “OC” star was reportedly at a friend’s Memorial Day BBQ when she began to feel ill after having a “few” cocktails.

Mischa is getting over a bout with bronchitis, following several weeks of intense travel, and apparently wasn’t aware that alcohol and antibiotics equal BAD!

She was rushed to a Los Angeles area hospital.

Mischa’s rep says she is “feeling much better.”
