A woman used ChatGPT to taper off a seizure medication. She cut her dose by one-fourth using a pill cutter. She hid the plan from her doctors. The drug controlled her severe epilepsy. She believed it caused side effects like stilted speech and slow thinking. She died after a prolonged seizure during a call with her father. Her father had urged her to follow her doctor’s advice. The incident occurred in early February 2026.
