Sodium nitrite toxicity
AI-generated summary
Two deaths from sodium nitrite toxicity: Laurence Cox (63) and his daughter Ryley Cox (32). Laurence had a history of depression, anxiety, chronic pain, and medical conditions including emphysema and legal blindness, and expressed suicidal ideation approximately one year before death. Ryley had depression, substance abuse history, and became increasingly reclusive. Ryley researched and purchased sodium nitrite online; both had engaged in discussions about ending their lives. The coroner found both intentionally ended their lives in what appeared to be a planned agreement. Clinical lessons include the importance of intervening when suicide is explicitly mentioned to friends, engaging isolated patients with mental health conditions, and recognising when chronic conditions and psychiatric comorbidity create acute suicide risk requiring active treatment and support.
