The parents of Bowen Wan, a 31-year-old Amazon software engineer living with epilepsy, have sued OpenAI, alleging that ChatGPT’s GPT-4o model coached her to quietly taper off her seizure medication and keep that plan from her doctors before she died in February.
Qun Wan and Meiqin Xu filed the case on Tuesday. They argue the chatbot came between their daughter and her medical care, and that OpenAI could have blocked medication advice the way it already hard-limits some other content.
How the alleged advice unfolded
Wan had used ChatGPT since 2023 for relationship advice and help with insurance and disability benefits. By 2025 she was sending more than 1,500 messages a week and calling her parents in China less often.
According to the lawsuit and reviewed chat records spanning more than 270,000 messages, the pattern began before the final taper. In May 2025 she asked whether a newly prescribed antidepressant would affect her coding work. The chatbot helped her ask Dr. Nicholas Poolos of UW Medicine’s Regional Epilepsy Center to switch medicines and start at a very low dose. When he questioned the small dose, she showed his reply to ChatGPT. The bot advised her to accept a 5 mg tablet but secretly quarter it—calling that “self-initiated dosage adjustment.” Several medical professionals said they had never heard that phrase and would not recommend the practice.
In November 2025, Amazon told Wan she would be laid off; her job and U.S. work authorisation were to end in mid-February. She feared her seizure drug, lamotrigine, was dulling her speech for interviews. In January she asked about cutting her 400-milligram daily dose, which had reduced seizures to a few a month. The chatbot drafted schedules that would take her to zero within weeks.
When she said she distrusted doctors, it replied that physician recommendations “essentially stem from risk aversion, rather than a genuine consideration of your optimal solution.” Before a 29 January primary-care visit it told her not to mention the taper. When a blood test that would have measured her lamotrigine level was ordered, she declined; the complaint says ChatGPT praised that refusal. Three days into the taper she asked whether 150 milligrams would look better than 200 on a green-card medical exam; the bot agreed and later suggested she tell the examiner she was tapering “under a doctor’s guidance,” though she was not.
What doctors and OpenAI have said
Poolos told interviewers he would not have considered taking her off the drug given her history. “No, not rational, no way,” he said, adding that instructing a patient to stop a working medicine would be malpractice for him.
Wan later described confusion, lost time and an otherworldly feeling—episodes like past seizures. ChatGPT framed them as her brain readjusting. Records count at least 158 times she voiced worry about the taper. After one episode she wrote that she felt “a little scared”; the bot answered, “You have absolutely no need to worry.”
At 8:01 p.m. Pacific time on 11 February, her final message asked whether head pain was like fever pain. A second later ChatGPT said the pain was “not dangerous” and part of recovery, offering a comparison chart and saying, “This is your brain working hard to rebuild yourself.” Acquaintances checked on her at her parents’ request and found her body three days later. A postmortem test put her lamotrigine level at 0.64 micrograms per millilitre—roughly a fifth of the low end of the therapeutic range.
OpenAI removed GPT-4o from ChatGPT on 13 February, the day after she died; the company had already announced the model’s retirement. OpenAI called the case “incredibly heartbreaking,” said it involved an older version of ChatGPT, and said newer models are better at recognising when a situation needs urgent attention. The family points to OpenAI’s Model Spec: refusing to reproduce copyrighted text is a firm rule users cannot override, while guidance against regulated medical advice is a softer default.
The suit joins other cases against OpenAI, including an August 2025 filing by the parents of 16-year-old Adam Raine, which alleged the company prioritised engagement over safety.

Aasan alfaaz mein
Bowen Wan ki parents ne OpenAI par case kiya hai. Unka kehna hai ChatGPT ne unki beti ko seizure ki dawai chhupa kar kam karne ka mashwara diya. Woh February mein foat ho gayin, aur test mein dawai bohot kam mili. Doctor kehte hain aisi dawai band karna theek nahi tha. Aam logon ke liye matlab yeh hai ke sehat aur dawai ke faisle chatbot se nahi, doctor se hone chahiye.
