The Liz and Dick actress' rep tells Us Weekly the star was taken to a hospital in New York City Sunday night after suffering an asthma attack.
Still, "Lindsay was treated and released, and is doing fine," the rep assured Us in a statement Monday.
TMZ initially reported that the Canyons star, 26, was being treated at Mount Sinai hospital for a lung infection, although her rep said the info regarding her ailment was incorrect.
Lohan's hospitalization comes just a few days after she was arrested for leaving the scene of an accident; the actress allegedly bumped into a pedestrian with her car in NYC's Meatpacking District around 1 a.m. on September 19.
