Brittany Murphy died from pneumonia, but anemia and prescription drugs also played a role, officials said yesterday.
The primary cause of death was community-acquired pneumonia, with contributing factors of iron deficiency anemia and "multiple drug intoxication," according to the Los Angeles County coroner's office.
The death was ruled accidental, The Associated Press reported.
Coroner's spokesman Craig Harvey declined to specify what types of drugs were involved but said they were all prescription medications. Details about the drugs the "Clueless" and "8 Mile" star had in her system will be released in several weeks when a complete report is done.
Murphy died Dec. 20 at age 32 after collapsing at her Hollywood Hills home. Her mother and husband have said the actress didn't abuse prescription medications or have an eating disorder.
Attempts to reach them for further comment were not immediately successful yesterday.
Murphy's husband, Simon Monjack, and mother, Sharon Murphy, told investigators the actress had been experiencing flulike symptoms in the days before she died.
A memorial for a foundation in Brittany Murphy's name that had been planned for yesterday was abruptly canceled with no explanation.
