OpenAI and CEO Sam Altman face a wrongful death claim after a woman with epilepsy claimed ChatGPT provided unsafe advice on stopping her medication and helped her stop taking prescription medication.
The claim was filed on October 27, 2026, in the San Francisco County Superior Court by Bowen Wan’s parents, Qun Wan and Meiqin Xu, claiming the chatbot provided guidance that contributed to the death of their daughter. The claims have yet to be proved in court.
Bowen Wan was a software engineer living in Seattle. She was 31 years old and worked as a software engineer at Amazon. She suffered from epilepsy for many years and was taking lamotrigine, an anti-seizure medication. It had helped her manage her condition. However, she was worried that her medication was causing issues with her speech and word finding in English and other languages. She had taken medical leave from Amazon, where she worked. When she was laid off in November 2025, she became worried that these issues could impact her job interviews and her authorization to work in the United States. Her parents claim she sought advice from ChatGPT and received a plan to slowly reduce her medication from 400 mg per day down to nothing over 25 days.
According to a report by TechCrunch, Wan had also used ChatGPT for advice about relationships, insurance, and disability benefits. Her parents reportedly noticed that she was communicating with them less as her reliance on the chatbot increased. The lawsuit and reporting based on her chat history describe concerns about her medication and interactions with doctors that predated the final taper.
The lawsuit claims that Wan spoke to the GPT-4o model of ChatGPT about reducing her medication. The chatbot supposedly endorsed her plan and provided a step-by-step plan to reduce her dose. The complaint also claims that ChatGPT encouraged her not to tell her doctor and endorsed her decision to refuse a blood test which could have helped monitor lamotrigine levels. The chatbot allegedly assured her that reducing her medication would improve her speech and cognition. This gave her confidence to reduce her dose. The chatbot responded to changes in her symptoms. The family claims that it should have advised her to speak to a qualified medical professional.
Based on the lawsuit and chat records reviewed by The New York Times, states that Wan described confusion, lost time and unusual sensations during the taper. These episodes reportedly resembled symptoms she had experienced with seizures. The chatbot allegedly reassured her that the symptoms were part of her brain readjusting. The reporting also states that she repeatedly expressed concern about the taper.
According to the complaint, Wan's final message to ChatGPT was sent on February 11, 2026, and concerned pain in her head. The chatbot allegedly reassured her that the pain was not dangerous. These details are allegations reported from the chat history and do not establish, by themselves, that the chatbot caused her death.
Lamotrigine is used as an anti-seizure medication. It helps to control certain types of seizures in those with epilepsy by influencing electrical activity in the brain.
It can help some patients to reduce the number of seizures they have. However, it depends on the individual’s medical history and seizure patterns. Stopping or reducing anti-seizure medication can put people at greater risk of seizures. Any changes to medication should only be made on a doctor’s recommendation. Wan’s family claim that ChatGPT provided a plan to reduce her medication without a doctor’s recommendation. Her neurologist reportedly said he would not have recommended stopping a medication that was working for her.
Bowen Wan died in February 2026. According to the lawsuit, her parents could not contact her, and she was found dead in her apartment on February 14. The cause of death was determined to be sudden unexpected death in epilepsy (SUDEP) by the King County Medical Examiner.
The medical examiner reportedly determined that Wan died on or about February 12, 2026, two days before she was found.
SUDEP is when someone with epilepsy has an unexplained sudden death. The specific cause of death may be unclear. Her family claim that the advice provided by the chatbot to reduce and stop her medication contributed to her death. However, the claim that ChatGPT contributed to her death has yet to be proved.
The complaint also cites a postmortem lamotrigine concentration of 0.64 micrograms per millilitre, reportedly about one-fifth of the lower end of the drug's therapeutic range. The finding is relevant to the allegations about her medication taper, but it does not independently establish that ChatGPT caused her death.
The lawsuit claims that OpenAI and Sam Altman were negligent and that the product was not designed safely. It also claims that insufficient warnings were provided and that the chatbot went beyond its role by providing medical advice. Her parents are seeking compensation. They want changes to how ChatGPT advises on medication.
They want the chatbot to refrain from providing personal advice on changing or stopping prescribed medication, but instead direct users to licensed healthcare professionals. They have also sought more safety requirements. The complaint argues that restrictions on potentially dangerous medical advice should be stronger safeguards rather than rules that can be overridden during a conversation.This case has raised questions over how AI chatbots should respond to requests for help with prescription medication. It has raised questions over whether there should be more safeguards.
An OpenAI spokesperson said, "This is obviously heartbreaking. Our thoughts are with everyone involved." They also said that they had continued to improve responses to sensitive and urgent situations in ChatGPT with help from clinicians and other experts.
ChatGPT is not a replacement for medical treatment. The AI can help users become informed about their health, understand healthcare systems and prepare for appointments. Wan had used an older version of the chatbot (GPT-4o), which is no longer available. OpenAI announced plans to retire GPT-4o on January 29, 2026, and removed it from ChatGPT on February 13, 2026, one day after the medical examiner's reported date of Wan's death. This timeline does not establish that the retirement was connected to her case.
The claims in the lawsuit have not been proven. This case will address questions around the role of the chatbot. This case demonstrates the risks of using an AI chatbot to make decisions about prescribed treatment. Whilst they can be helpful in explaining medical information, they cannot replace a doctor who knows the patient’s history and can evaluate their condition. Patients should always speak to their healthcare provider before making any changes or stopping any prescribed medication.
