Brittany Murphy was left vulnerable due to...

Severe anemia left actressÂ Brittany Murphy very weak and vulnerable to pneumonia and the prescription meds she was using to treat it. This was according to the autopsy report released on Thursday.

In the report it was stated that Murphy's menstrual period contributed to her anemiaÂ and left her in a weakened state and vulnerable to infection. It also contributed the effects that a host of drugs, including hydrocodone and acetaminophen, had on the 32-year-old actress, according to the autopsy report.

Murphy's death wasÂ accidental, but preventable according to coroner'sÂ officials. She died afterÂ collapsingÂ in her home in the Hollywood Hills on Dec. 20.

The report also stated that the medications found in her system were consistent with the treatmentÂ of a cold or respiratory infection.

Murphy's mother and husband reported the actress was ill with flu-like symptoms in the days before her death.

TheÂ autopsy showed no abuse of drugs.Â Â Â Investigators found numerous prescription medications in the actress' home, which she shared with her mother, Sharon, and husband, Simon Monjack.

Murphy was takingÂ anti-seizure medications and hydrocodone, according to the report.

Murphy had been complaining of severe abdominal pain for seven to 10 days before her death. The report states her family thought it was a result of her menstrual period, which they told investigators was often severe.

The "Clueless" and "8 Mile" star had a doctor's appointment scheduled, but sadly she died before her appointment, Assistant Chief Coroner Ed Winter has said.

The autopsy report noted Murphy suffered from diabetes and had to go to the hospital for treatment in Oregon in April 2009.

The reported said she was healthy otherwise.

In an interview in January, Monjack saidÂ he and Murphy were planning a family and contemplating a move to New York before her death. He said his wife had been taking anti-seizure medications after a health episode she experienced while filming "8 Mile."

Her big screen roles diminished after 2005's "Sin City," but Murphy had been juggling several movie projects in the months before her death.
