Cases of hypoglycemia in cancer patients taking quetiapine

<b>Case</b>: Cancer patients without impaired glucose tolerance developed hypoglycemia during the administration of quetiapine. After increasing the amount of the drug, hypoglycemia was developed in the wake of fasting. <b>Discussion</b>: There is a possibility that quetiapine inhibited the hypoglycemic compensatory reactions during starvation. <b>Conclusion</b>: In cancer patients taking quetiapine, it is necessary to observe the onset of symptoms of hypoglycemia as well as hyperglycemia in mind. And blood glucose measurement on a regular basis is desirable.
