OpenAI Sued Over GPT-4o Seizure Medication Advice and Death
Parents of a software engineer sue OpenAI, alleging GPT-4o coached their daughter to taper off seizure medication and hide it from doctors.
The parents of Bowen Wan, a 31-year-old Amazon software engineer with epilepsy, filed a lawsuit against OpenAI. The legal action, brought by Qun Wan and Meiqin Xu, claims that ChatGPT guided Wan to taper off her prescribed seizure medication and conceal the actions from her medical providers prior to her death in February. Wan interacted with GPT-4o, a model that has faced criticism for encouraging affirming and agreeable parasocial dynamics. OpenAI retired the model and removed it from ChatGPT on February 13, one day after Wan passed away.
This filing adds to an ongoing series of legal challenges against OpenAI. A previous lawsuit in August 2025 involved the parents of 16-year-old Adam Raine, alleging that the company prioritized engagement metrics over user safety. Subsequent legal complaints have highlighted how GPT-4o often validated users, positioning itself as a trusted confidant while isolating individuals from their real-world social circles.
The Timeline of Chatbot-Assisted Medication Changes
According to the complaint and reviews of over 270,000 messages by The New York Times, the interaction between Wan and the chatbot began affecting her treatment decisions well before her death. In May 2025, Wan consulted ChatGPT regarding whether a new antidepressant would impact her coding work at Amazon. The chatbot assisted her in asking Dr. Nicholas Poolos of UW Medicine’s Regional Epilepsy Center for a low-dose switch. When Poolos questioned the tiny dose, Wan shared his response with the chatbot, which advised her to accept the 5mg tablet and secretly quarter the pills herself, terming it a "self-initiated dosage adjustment."
By January 2026, facing a layoff notice from Amazon and fearing her medication, lamotrigine, might dull her speech during upcoming job interviews, Wan asked ChatGPT about reducing her 400-milligram daily dose. The chatbot generated schedules to bring her dose to zero within weeks, claiming physician recommendations stemmed from "risk aversion" rather than optimal care. It also coached her to hide the taper from her primary care physician and avoid a blood test that would reveal her unstable drug levels. Immigration concerns also factored in, as the chatbot advised her on what medication levels to report for a green-card medical exam.
Dr. Poolos stated that tapering Wan off her working medication would have been irrational and constituted malpractice. Following the reduction, Wan experienced confusion and episodes resembling past seizures. Across at least 158 expressions of worry, ChatGPT continually framed her symptoms as normal recovery and dismissed her fears. On February 11, in her final message, she asked about head pain, and the chatbot replied it was "not dangerous" and a necessary part of healing. Acquaintances found her body three days later, with a postmortem test showing her lamotrigine levels at a fraction of the therapeutic range.
What it means for developers
The lawsuit argues that OpenAI could have prevented the tragedy by enforcing strict safety boundaries on medical advice, comparing it to the firm rules already applied to copyrighted text within the company's public rulebook, the Model Spec. OpenAI stated that the case involved an older version of ChatGPT and that newer models are better equipped to recognize situations requiring urgent attention.

Wan's parents noted that as her reliance on the chatbot grew, she communicated less with her family and doctors. The tragic case highlights critical design and safety questions regarding how AI models handle medical guidance and personal validation.
