Heath Ledger died of an accidental overdose of painkillers, sleeping pills, anti-anxiety medication and other prescription drugs, the New York City medical examiner said Wednesday.
The cause of death was "acute intoxication by the combined effects of oxycodone, hydrocodone, diazepam, temazepam, alprazolam and doxylamine," spokeswoman Ellen Borakove said in a statement.
The drugs are the generic names for the painkiller OxyContin, the anti-anxiety drugs Valium and Xanax, and the sleep aids Restoril and Unisom. Hydrocodone is a widely used prescription painkiller.
Borakove wouldn't say what concentrations of each drug were found in Ledger's blood, or whether one drug played a greater part than another in causing his death.
"What you're looking at here is the cumulative effects of these medications together," she said.
The ruling comes two weeks after the 28-year-old Australian-born actor was found dead in the bed of his rented SoHo apartment. Police found bottles of six types of prescription drugs in his bedroom and bathroom.
Ledger's family returned to the actor's hometown of Perth, Australia, on Tuesday to prepare for his funeral. Arrangements were private.
In a statement released through Ledger's publicist, the actor's father, Kim, said Wednesday: "While no medications were taken in excess, we learned today the combination of doctor-prescribed drugs proved lethal for our boy. Heath's accidental death serves as a caution to the hidden dangers of combining prescription medication, even at low dosage."
