"Extra" obtained the Calls for Service report from the Santa Monica Police Department, which shows the reason for the 911 call from Wilson's house to be a suicide attempt.
He was hospitalized in good condition Monday, a day after he was taken from his home by ambulance, a hospital spokeswoman said.
"I respectfully ask that the media allow me to receive care and heal in private during this difficult time," Wilson said in a statement released through publicist Ina Treciokas.
No further comments were expected, she said.
The actor was at Cedars-Sinai Medical Center in Los Angeles. He was transferred there from St. John's Health Center in Santa Monica.
It was not known why he was hospitalized, but Santa Monica Fire Battalion Chief Jose Torres said Monday that the department responded to a call that involved the 38-year-old actor.
The chief would not comment on Wilson's injuries or condition, citing federal privacy laws.
"These guys were kind of taking their time taking a stretcher out of the ambulance, then they went into the house," said neighbor Geoffry White, 61, who lives directly across the street from the actor.
According to "Entertainment Tonight," Wilson was later brought to the Beverly Hills' Cedars-Sinai Hospital where he detoxed. The show also reported that brother Luke Wilson was spotted leaving Cedars-Sinai on Sunday night with their brother, Andrew. People magazine said Owen's parents also visited.
Most recently, he starred in "Night at the Museum" with Ben Stiller.
It was unknown if Wilson's hospitalization would affect his appearance opposite Jennifer Aniston in the 20th Century Fox comedy "Marley & Me."
A Fox spokesman told the Hollywood trade paper Daily Variety that "it's a totally inappropriate question at this time" whether he would appear in the movie.
Wilson's hospitalization could also keep him from helping to promote "The Darjeeling Limited," in which he stars alongside Adrien Brody and Jason Schwartzman. The Fox Searchlight film was to be released next month.
Paramount also had a Wilson film due out in March: the Judd Apatow-produced "Drillbit Taylor."
