Heath Ledger's Dad Reveals Actor's Last Words

The night before Heath Ledger died in 2008 from a lethal drug overdose, his sister Kate warned him not to mix prescription medications.

"The last conversation Kate had with him was this discussion about his medications and she warned him, "You can't mix drugs that you don't know anything about'," Ledger's father Kim told news.com.au.

"He said 'Katie, Katie, I'll be fine'.

The 28-year-old died from a lethal combination of several different prescription medications in his New York apartment.

The toxicology report found that Ledger's death was the result of "acute intoxication by the combined effects of oxycodone, hydrocodone, diazepam, temazepam, alprazolam and doxylamine", and his death was "accident, resulting from the abuse of prescribed medications."

Ledger says his son was not addicted to opioids, but simply made the mistake of mixing the wrong drugs.

"It was a one-off thing," he said.

"That's what killed us, because he was warned by his sister the night before: 'You shouldn't mix what you're taking for pnemonia with your ambien'. But most of Heath's problems were self-induced."

His hectic work schedule had begun to take its toll, Ledger said.

"Heath mixed a couple of drugs together with sleeping tablets and he's gone forever. That's something we (himself, wife Sally and sister Kate) just have to deal with."

"Losing a child is something that never leaves you. You can live with the pain, but it never leaves you."
