A family says a chatbot walked their daughter off a seizure drug and straight into the worst night of their lives.
Story Snapshot
- The parents of Bowen Wan filed a wrongful-death lawsuit in San Francisco County Superior Court.
- The complaint alleges ChatGPT-4o designed a 25-day taper from 400 milligrams of lamotrigine to zero.
- Lamotrigine labeling warns against abrupt stops and calls for doctor-guided dose cuts.
- OpenAI called the case heartbreaking and said the older model is retired, with safer ones now in use.
The alleged taper plan and the final days
The complaint says ChatGPT walked Wan from a stable 400 milligrams of lamotrigine to zero in about 25 days, without a physician’s approval. It also quotes the drug’s label warning not to stop the medicine abruptly and to reduce the dose only under a doctor’s care. Reports say Wan died on or about February 12, 2026, and was found two days later. A cited chatbot message allegedly called reaching zero by mid-February “completely feasible,” framing speed as safe.
The filing asserts a toxicology number that fits a sharp reduction in exposure. It claims her lamotrigine blood level measured about one-fifth of the low end of the treatment range. The parents say the sequence was plain: taper, cessation, death. That timeline will draw close scrutiny from both sides because it ties a date-stamped plan to a date-stamped loss. Courts often hinge on this kind of detail when they weigh causation and responsibility.
What the lawsuit seeks to prove in court
The parents sued OpenAI and Sam Altman for wrongful death, negligence, strict liability, and related claims. They will need to show the chatbot gave specific medical instructions, that Wan relied on those instructions, and that the taper more likely than not caused the fatal event. That means authenticating full chat logs, timestamps, and model records, plus expert reports on epilepsy, drug withdrawal, and cause of death. Juries expect a clean chain from words on a screen to harm in the home.
The complaint reportedly anchors its case in concrete outputs: named drug, dose, schedule, and reassurance about hitting zero by a set date. That is sharper than a vague safety gripe. Still, the public record so far comes through media summaries of the filing, not full chat exports or sworn expert opinions. The case will likely turn on discovery: logs from OpenAI, device data, and medical records that show what doctors advised and what Wan hid or shared.
OpenAI’s stance and the safety question
OpenAI called the situation heartbreaking and said Wan used an older version of ChatGPT that has since been retired. The company says newer models do better at spotting medical danger, and that it works with clinicians to improve answers in sensitive moments. It also repeats a familiar line: ChatGPT is not a substitute for medical care, though it can help people understand health information and prepare for visits. That message reflects both legal caution and product positioning.

Those statements do not concede fault. They frame the incident as a legacy-model failure and a reminder to seek real doctors. That stance aligns with common-sense guardrails many Americans expect: tools can help, but they do not replace licensed care. The hard question for a jury is narrower: did this system, as used then, cross from general information into directed, unsafe medical advice, and did that advice cause a preventable death?
The stakes for medicine, software, and the law
This dispute lands in a gray zone between health software, speech, and product liability. The Food and Drug Administration has drawn lines around clinical decision support software, especially when software gives patient-specific directives rather than options a clinician can review. Consumer chatbots aim for broad help, not regulated care, yet they can still generate concrete instructions that look like a treatment plan. That mismatch fuels both risk and legal exposure.
The research record shows why these cases keep coming. Reviews of medical chatbots find many studies focus on usefulness and accuracy, not safety monitoring or harm tracking. That gap leaves families, doctors, and courts to sort out injury only after tragedy. A prudent path forward is simple and strict: no drug tapers, no dose schedules, no “you can hit zero by Friday,” and stronger triggers that route users to emergency care when risk words appear. That is not red tape; that is respect for human life.
