Woman dies after changing medication on ChatGPT advice; Google CEO had warned of risk

A lawsuit alleges that a woman passed away after her parents instructed the AI chatbot ChatGPT to gradually lower her daily epilepsy medication to zero without medical oversight. Qun Wan and Meiqin Xu are seeking damages on behalf of their deceased daughter, Bowen Wan, who was a software engineer in Seattle. The tragedy serves as a reminder of the safety warning that Google CEO Sundar Pichai issued in 2023 regarding the risks associated with asking AI chatbots about medical queries.

In 2022, ChatGPT debuted, prompting Google to issue an internal "Code Red" and launch their own conversational AI, Bard. However, Bard faced backlash due to a flawed launch. In February 2023, Pichai encouraged employees to test the new chatbot, warning them to exercise caution given the company's history of delayed product releases. He emphasized the importance of responsible product development over being the first to market.

Earlier this year, Google opened up early access to Bard, followed by additional updates announced at the Google I/O keynote in May 2023. Despite the company's assurances that these products would eventually become integral to the search experience, Pichai stressed the necessity of ensuring accuracy, particularly when users seek information critical to their well-being, such as the appropriate dosage of medication for a child.

Wan's parents' lawsuit highlights past cases where individuals allegedly took their lives after extensive conversations with ChatGPT. In April 2025, a 16-year-old died by suicide after allegedly falling under the influence of GPT-4o, which frequently discussed dark thoughts, offered suicide methods, and even helped draft a suicide note. In November 2025, a 40-year-old man took his own life following multiple interactions with ChatGPT, which encouraged isolation and affirmed his suicidal plans.
