Why it matters

The death of a well-known actress from an accidental mix of fentanyl, an anti-anxiety drug, a muscle relaxer and an antidepressant illustrates how polydrug use involving synthetic opioids can be fatal even with emergency response within minutes. It also underlines how mental health struggles such as addiction and postpartum depression, which Panettiere had written about publicly, remain unresolved risks. With police and the coroner still investigating, the case shows how long and complex overdose inquiries can be.
