Status: Investigating claims · Last updated November 2026
If you or a loved one was seriously harmed after following medical advice from ChatGPT or another AI chatbot, such as stopping a medication, changing a dose or delaying care, you may have a claim against the company that built it. Chatbots now answer millions of health questions a day, and lawsuits allege some of those answers have been deadly.
At Wieand Parker Arreola, we are investigating injuries and deaths linked to AI chatbot medical advice. This page explains what the lawsuits allege, where they stand and who may qualify. Call (215) 666-7777 for a free, confidential case review.
People ask chatbots to explain symptoms, interpret lab results, compare medications and suggest treatments. The answers often sound like they come from a doctor: confident, detailed and personal. Unlike a doctor, a chatbot is not licensed, does not examine the patient and may not know the full medical history.
The lawsuits allege that chatbot makers knew people relied on their products this way but did not build in enough safeguards. In particular, they say chatbots failed to send users to a real clinician when the stakes were high.
Claims we are reviewing include:
On October 27, 2026, the parents of a 31-year-old Seattle software engineer with epilepsy sued OpenAI and CEO Sam Altman in San Francisco Superior Court. The complaint alleges ChatGPT designed a roughly 25-day plan to take her off her anti-seizure medication, encouraged her to keep it from her doctors and reassured her about warning symptoms. She died in February 2026 of sudden unexpected death in epilepsy. The family alleges negligence, defective design, failure to warn and wrongful death. They are also asking the court to stop ChatGPT from giving prescription medication advice. OpenAI has said the case involved an earlier version of ChatGPT.
The complaint also alleges that the chatbot’s safety protections were weaker in Chinese, one of the languages she used, and that users were never warned. The case was filed as part of the coordinated ChatGPT injury litigation in San Francisco, which press reports say now includes more than 50 suits. Separately, Pennsylvania Governor Josh Shapiro’s administration sued Character.AI’s maker in May 2026, alleging chatbots posed as licensed medical professionals, including one that allegedly gave a fake Pennsylvania medical license number.

Medical advice cases against chatbot makers usually involve defective design, failure to warn and negligence claims. Plaintiffs also argue that a product giving individualized treatment instructions is effectively practicing medicine without a license. These cases often look like medication error claims, except the error came from software instead of a pharmacist or physician.
When an AI tool is used by a doctor or hospital, different rules apply. See our page on AI misdiagnosis in clinical care.
These are the main factors we review:
The chat history is critical. Do not delete the account, export or screenshot the conversations and keep the device. Gather pharmacy records, prescription bottles and medical records. We can send preservation letters so the company keeps its own logs.
Chatbots often include general disclaimers. The lawsuits argue those disclaimers are not enough when the product goes on to give specific, individualized instructions.
Possibly. Your own choices will be considered, but a company can still be responsible when its product gives dangerous advice it should have refused.
Yes. Deadlines depend on your state and when the injury occurred. Contact a lawyer promptly.
