Quetiapine and Risperidone Treatment for Hypokalemia in Patients with Schizophrenia (English)

Hypokalemia can cause disorders in multiple systems of the body. Long-term use of certain antipsychotic medications may lead to abnormalities in electrolyte metabolism, including changes in serum potassium levels. We reported a case of a 49-year-old woman with schizophrenia who developed hypokalemia after taking quetiapine and risperidone. When she switched to another antipsychotic medication (amisulpride), her potassium levels returned to normal. We also discussed the possible mechanisms behind antipsychotic-induced hypokalemia, as well as clinical considerations related to this condition.
