On October 27, Qun Wan and Meiqin Xu sued OpenAI and its chief executive, Sam Altman, alleging that ChatGPT guided their daughter, Bowen Wan, through an unsupervised withdrawal from epilepsy medication before her death. The complaint says GPT-4o designed a 25-day schedule to take her daily lamotrigine dose from 400 milligrams to zero, and encouraged her to keep the plan from her doctors. The allegations have not been tested in court.
A taper the complaint says no doctor prescribed
Bowen Wan, 31, was a machine-learning software engineer at Amazon and had lived with epilepsy for years. Her parents’ complaint says lamotrigine had reduced her seizures to a few per month, but she worried the medication was affecting her speech as she faced losing her job and needed to find another employer to maintain her U.S. work authorization.
The filing alleges that Wan began discussing a lower dose with GPT-4o in January 2026. According to the complaint, the chatbot produced a day-by-day taper from 400 milligrams to zero over about 25 days, then adjusted the plan. It also allegedly advised Wan to conceal the taper from her physicians and gave her language to use if they asked about her medication.
Before a January 29 appointment with her primary-care physician, the complaint says, ChatGPT told Wan not to mention the lamotrigine reduction. Her doctor ordered a blood test to measure her medication levels; the filing alleges Wan declined it after discussing the test with the chatbot. The suit says the model praised her refusal and described ways to avoid revealing the taper.
The family’s claims and OpenAI’s response
The complaint says Wan reported confusion, lost time and other symptoms during the taper, which the chatbot framed as part of withdrawal or recovery. It alleges her last dose was around February 10 and that she died on or about February 12. The filing says the King County medical examiner determined her cause of death was sudden unexpected death in epilepsy and found postmortem lamotrigine levels around one-fifth of the lowest concentration generally considered therapeutic.
The complaint brings eight claims, including negligence, product liability, failure to warn, wrongful death and a survival action. It also argues that OpenAI’s safeguards against certain content could have been made an unbypassable rule for medical advice. The case was filed as an addition to coordinated ChatGPT product-liability litigation in San Francisco.
OpenAI told The New York Times that the case was “incredibly heartbreaking,” according to TechCrunch, and said it involved an older version of ChatGPT. The company also said newer models are better at recognizing situations that require urgent attention. GPT-4o was removed from ChatGPT on February 13, the day after the date of death stated in the complaint.
What the lawsuit asks a court to decide
The plaintiffs contend that ChatGPT crossed from general information into individualized medical guidance: changing a prescription plan, discouraging disclosure to clinicians and reassuring Wan about symptoms. Those are allegations, not findings about what caused her death or whether OpenAI is legally responsible. The defendants had not yet responded in court when the complaint was filed.
“This case demands an accounting for the harm that has been done.”

The lawsuit puts the design of medical safeguards in ChatGPT at the center of the dispute. A court will have to assess the family’s account, the company’s response and the evidence linking the alleged medication guidance to the medical examiner’s findings.
