The Greenville County Coroner's Office in South Carolina has officially confirmed Hayden Panettiere's cause of death. According to the ruling, the actress died from the combined toxic effects of fentanyl, 4-ANPP, alprazolam, methocarbamol and quetiapine. The report classifies the death as accidental.
Fentanyl is a potent synthetic opioid used as a painkiller, while 4-ANPP is a chemical precursor used in the illegal manufacturing of fentanyl. Alprazolam, known commercially as Xanax, is a commonly used benzodiazepine. Methocarbamol, sold under the brand name Robaxin, is a prescription muscle relaxant, and quetiapine, under the brand name Seroquel, is an antipsychotic used to treat schizophrenia, bipolar disorder and major depression.
How the events unfolded
Panettiere, known primarily for her leading roles in NBC's Heroes and ABC's Nashville, died on Sunday, August 16, at age 36. A friend of the actress called 911 to report an unconscious woman. In the audio of the call, emergency services mentioned the terms overdose and cardiac arrest in reference to the moment of death.
Paramedics attempted to resuscitate her using advanced cardiac life support, but Panettiere was pronounced dead at the scene.
An open struggle with depression and addiction
Panettiere had spoken publicly on various occasions about her mental health struggles and her relationship with drugs and alcohol. In an interview with People magazine, the actress recounted that at age 15 she was given what she described as happy pills.
She landed the role in Heroes at age 16, and over time began drinking and occasionally using opioids. My saving grace was that I couldn't lose control while I was on set working, she explained in that interview. But things would spiral out of control off set. And as I got older, drugs and alcohol became something I could hardly live without.
