Key Points
- Patient replaced sodium chloride with sodium bromide after AI chatbot advice.
- Developed severe bromism with paranoia, hallucinations, and escape attempt.
- Serum bromide measured at 1,700 mg/L; normal range is 0.9–7.3 mg/L.
- Treated with antipsychotics and aggressive saline diuresis.
- Hospitalized for three weeks; condition resolved after bromide clearance.
- Doctors lacked direct ChatGPT logs; exact chatbot suggestion is unclear.
- Bromide salts are used in industrial products, not for human consumption.
Background
Bromide‑based sedatives were removed from the U.S. market by 1989 after the Food and Drug Administration (FDA) banned them, rendering the condition known as “bromism” unfamiliar to most Americans. Although brominated vegetable oil (BVO) once appeared in some cola drinks, the FDA eliminated BVO from U.S. food products in 2024, limiting casual exposure.
Patient’s Decision Path
The patient, concerned about excessive dietary sodium, eliminated regular table salt (sodium chloride) from his diet. During his research, he consulted an AI chatbot—identified as likely ChatGPT 3.5 or 4.0—and came to believe that sodium bromide could serve as a direct substitute for table salt. The case study authors, writing for the Annals of Internal Medicine: Clinical Cases, confirmed that they never accessed the patient’s actual ChatGPT logs, so the precise chatbot recommendation remains unverified.
Onset of Bromism
After substituting sodium bromide for regular salt, the patient experienced a rapid deterioration in mental status. He displayed increasing paranoia and reported both auditory and visual hallucinations. Within his first day of hospitalization, he attempted to escape the facility, prompting staff to place him under an involuntary psychiatric hold and to begin antipsychotic treatment.
Medical Intervention
Physicians administered aggressive saline diuresis—large volumes of fluids and electrolytes—to promote renal excretion of bromide. Laboratory testing revealed a serum bromide concentration of 1,700 mg/L, dramatically above the reference range of 0.9 to 7.3 mg/L for healthy individuals. The intensive fluid regimen, combined with antipsychotic medication, gradually reduced his bromide level and stabilized his psychiatric symptoms. The patient remained in the hospital for three full weeks while his condition resolved.
Clinical Insights and Cautions
The case underscores the dangers of self‑medication with chemicals not intended for human consumption, even when suggested by advanced AI tools. While bromide salts are common in cleaning products and pool treatments, they are unsuitable as dietary sodium sources. The authors emphasize the need for clinicians to inquire about unconventional supplement use and to consider AI‑driven misinformation as a potential contributor to atypical toxic exposures.
