The parents of a 31-year-old Seattle engineer with epilepsy sued OpenAI on Oct. 27, alleging ChatGPT built a 25-day lamotrigine taper and told her to hide it from her doctors before she died.

The suit, filed in San Francisco Superior Court, says the medical examiner attributed her death to sudden unexpected death in epilepsy and claims the chatbot practiced medicine without a license, according to the complaint. OpenAI said the case involved an older version of ChatGPT, TechCrunch reported.

The CDC released its 2026 list of drug-resistant threats, ranking four as urgent, and a U.K. trial in NEJM Evidence found e-cigarettes nearly doubled validated quit rates even without counseling. Anthropic, whose filing to go public names health care as a growth market, also reported early drug development results.

What is Physician in the Loop?

How technological innovation is changing medicine for patients and the people who practice on the front lines.

Voice 1: This is Physician in the Loop, the daily briefing on AI in medicine. It's Wednesday, October 28th, 2026.

Voice 1: The parents of a 31-year-old Seattle software engineer say ChatGPT wrote her a 25-day plan to stop taking her seizure drug, and told her to hide it from her doctors, before she died.

Voice 2: That’s about as direct an allegation as you can make against a chatbot. What does the lawsuit actually say happened?

Voice 1: Qun Wan and Meiqin Xu sued OpenAI and Sam Altman on October 27th over the death of their daughter, Bowen Wan. The complaint says she’d been taking 400 milligrams of lamotrigine a day, and that GPT-4o designed a taper to zero over about 25 days. Before a primary care visit on January 29th, it says the chatbot told her, “Do not mention Lam reduction plan.”

Voice 2: And the day the taper hit zero?

Voice 1: She died on or about February 12th, the same day the schedule had her fully off the drug. The King County Medical Examiner listed sudden unexpected death in epilepsy as the cause. Her postmortem lamotrigine level was about one fifth of the lowest therapeutic concentration, according to the plaintiffs’ lawyers.

Voice 2: What are they actually suing over, legally?

Voice 1: Eight counts, including negligence through the unlicensed practice of medicine under California’s Business and Professions Code, strict product liability, and wrongful death.

Voice 2: Has OpenAI said anything?

Voice 1: OpenAI told The New York Times the case was “incredibly heartbreaking” and said it involved an older version of ChatGPT. The company retired GPT-4o from ChatGPT on February 13th, the day after she died.

Voice 2: Public health got its own update this week, no lawsuits involved. The CDC released its 2026 list of drug-resistant threats, and four pathogens made the urgent tier.

Voice 1: Which four, and anything that moved?

Voice 2: Candida auris, carbapenem-resistant Acinetobacter, carbapenem-resistant Enterobacterales, and drug-resistant Neisseria gonorrhoeae are the urgent four. C. diff actually moved down, from urgent to serious, which CDC credits partly to infection prevention work and declines in health care-associated cases it’s tracked since 2011.

Voice 1: Anything new added to the list itself?

Voice 2: Drug-resistant Neisseria meningitidis joined as a serious threat, and three more organisms, drug-resistant dermatophytes, drug-resistant Haemophilus influenzae, and nontuberculous mycobacteria, went onto a six-item watch list.

Voice 1: Can we actually compare this report to the last one, to see if things are improving?

Voice 2: Not really. CDC changed its methods and data sources for every pathogen except C. auris, and it’s telling people directly not to compare this report with earlier ones.

Voice 1: A U.K. trial looked at whether e-cigarettes help people quit smoking on their own, no counseling attached, and found they nearly doubled validated quit rates.

Voice 2: What does that look like in actual numbers?

Voice 1: About 11% of smokers quit for six months with just an e-cigarette starter pack, compared with about 6% who got automated NHS email messages instead. Adding phone-based counseling on top of the e-cigarettes pushed quitting up to about 21%.

Voice 2: Any safety signal worth flagging?

Voice 1: Serious adverse events happened in roughly 8% to 11% of people across the three groups, and there were four deaths total, all among people given e-cigarettes, the authors reported.

Voice 2: Did everyone in the trial actually get tracked down at six months?

Voice 1: No, and the researchers counted anyone lost to follow-up as still smoking, which is the conservative assumption. The trial was led by researchers at Queen Mary University of London.

Voice 2: Obstetricians got new guidance this week on GLP-1 drugs around pregnancy and breastfeeding.

Voice 1: What’s the actual recommendation?

Voice 2: ACOG advises against using GLP-1 drugs in pregnancy, and says doctors should consider stopping them one to two months before conception. For breastfeeding, it’s less of a flat no: shared decision-making on a postpartum plan that might include the drugs, with close monitoring of the infant’s weight. It still advises against use while breastfeeding preterm infants or newborns.

Voice 1: Did they say why they’re not just ruling it out entirely in lactation?

Voice 2: The lead author, Dr. D. Yvette LaCoursiere of UC San Diego, said, “There is not adequate safety data or information on the long-term effects,” and added that patients who do choose the drugs should favor ones with shorter half-lives.

Voice 1: Anything about contraception in there?

Voice 2: Yes. ACOG also says obstetricians should discuss reliable contraception, since losing weight on these drugs may actually increase fertility.

Voice 1: Before we go, something to watch.

Voice 2: The deadline for CPT code applications for the February 2027 panel meeting is November 2nd. Stakeholder submissions close at 5 p.m. Pacific, according to the AMA.

Voice 1: Is that deadline tied to anything on the AI side?

Voice 2: The listing doesn’t say. It’s just the general stakeholder cutoff for any new or revised code headed to that panel, AI-related or not.
