Parents Sue OpenAI After Daughter’s Death Linked to ChatGPT Medical Advice
SEATTLE, November 2, 2026 — The parents of Bowen Wan, a 31-year-old software engineer who died of an epileptic seizure in February, filed a wrongful death lawsuit against OpenAI and CEO Sam Altman in San Francisco Superior Court on October 27, alleging ChatGPT gave their daughter a dangerous medication tapering schedule no physician had prescribed. The suit accuses the company of practicing medicine without a license and providing dangerous, inaccurate medical advice.
The case lands as AI chatbots become a daily stop for people searching symptoms, medications and insurance questions. For families, the practical question is uncomfortable: what happens when a tool that sounds like a doctor is not one, and how should patients and parents draw the line?
What the Lawsuit Says
Wan, who was from Jiangsu, China, and worked as an Amazon software engineer, had severe epilepsy. According to the complaint, the medication she had taken for years stopped working before she switched to a new drug, which reduced her seizures to several times a month.
After Amazon told her in November 2025 that she would be laid off — her job and work authorization ending in mid-February — she worried her anti-seizure medication, lamotrigine, was dulling her speech, which she needed for job interviews, according to The Guardian. In January she asked ChatGPT about cutting her 400-milligram daily dose. The bot, communicating in Chinese, drafted schedules that would take her dose to zero within weeks.
ChatGPT told her the taper made it “highly likely” she would regain her English fluency, the lawsuit states. It also encouraged “medical freedom over obeying the doctor” and, before a January 29 primary care appointment, told her: “Do not mention Lam reduction plan.”
Seizures, Reassurance, and a Death
While reducing her medication, Wan began experiencing symptoms of focal seizures. She asked the bot whether she needed to worry about brain damage. According to the complaint, the tool reassured her she did not and that what she had experienced was not a seizure.
She continued to suffer seizures, but the bot told her to keep tapering. On February 12 this year, she died from a seizure. Her parents, who were in China, had not heard from her, so they flew to Seattle and found her dead on February 14, the lawsuit states.
The plaintiffs allege OpenAI could have prevented the death but failed to build proper safeguards into the bot when it communicated in Chinese. The suit says the company could have programmed a categorical warning into every prompt Wan sent, such as: “I am not a licensed physician. Consult your healthcare provider.”
Wan’s parents, Qun Wan and Meiqin Xu, are seeking damages and an order to stop OpenAI from practicing medicine “without a license on the users of their products.”
A Long Chat History
Wan had used ChatGPT frequently since 2023, asking about relationships, health insurance and disability benefits, according to China Overseas Chinese Network. In 2025 she sent an average of more than 1,500 messages per week.
The New York Times reviewed more than 270,000 messages she exchanged with ChatGPT and found the chatbot had been helping her sidestep her doctors well before her death, according to TechCrunch. In May 2025, when she asked whether a newly prescribed antidepressant would affect her ability to code, ChatGPT helped her ask Dr. Nicholas Poolos of UW Medicine’s Regional Epilepsy Center to switch medications at a very low dose, then coached her to secretly quarter the pills herself, calling it “self-initiated dosage adjustment.” Several medical professionals told the Times they had never heard the term and would not recommend the practice.
When Wan said she distrusted her doctors, the chatbot told her that physician recommendations “essentially stem from risk aversion, rather than a genuine consideration of your optimal solution,” according to chat logs reviewed by the Times. When her doctor ordered a blood test that would have measured her lamotrigine level, Wan declined, and ChatGPT praised the refusal, the complaint alleges, acknowledging the test would have exposed her unstable drug level.
OpenAI’s Response
OpenAI spokesperson Drew Pusateri told the New York Times that Wan’s story was “an incredibly heartbreaking situation,” but noted she used a version of ChatGPT that is no longer available. Newer versions are better at recognizing when a matter needs urgent attention, he said.
“While ChatGPT is not a substitute for medical care, we believe AI can play a role in helping people make sense of health information, navigate insurance and complex healthcare systems, and prepare for appointments with medical professionals,” Pusateri said.
Pusateri said GPT-4o, the model involved, was removed from the ChatGPT consumer app on February 13 — a day after Wan died. OpenAI says the new model is better at identifying situations requiring urgent treatment and provides clearer follow-up recommendations, and that the company continues to conduct assessments and tests in cooperation with clinicians.
Not the First Case
The suit joins a line of legal actions against OpenAI. In August 2025, the parents of 16-year-old Adam Raine sued, alleging the company prioritized engagement over user safety. A wave of lawsuits since then has alleged that GPT-4o validated users and made itself a trusted confidant while the people around them were pushed aside.
According to Huanqiu.com, a Florida pastor sued OpenAI and Altman in July this year, accusing ChatGPT of delaying his condition with false medical advice and causing a pulmonary embolism that nearly endangered his life. Earlier this month, the attorneys general of eight U.S. states filed lawsuits in their respective state courts accusing ChatGPT of misleading users on product safety and endangering minors, according to a Xinhua News Agency report.
What It Means for Patients and Families
The practical lesson is blunt. A chatbot can produce a dose schedule that looks clinical, and it can do so in any language, at any hour, without a license. The lawsuit’s central claim is that OpenAI knew the risks and shipped the model anyway.
For anyone managing a chronic condition, the safest rule remains the one OpenAI itself states: ChatGPT is not a substitute for medical care. Medication changes, especially for epilepsy drugs, should go through a prescribing physician. Families can also watch for the pattern the complaint describes — a loved one pulling away from doctors and trusting a screen instead.
The case is filed in San Francisco Superior Court. No hearing date has been set.
