Background And Objective:
Metamizole is a non-opioid ampyrone sulfonate compound with potent analgesic, antipyretic, and spasmolytic effects. Agranulocytosis is a rare life-threatening complication of metamizole.
Case:
Here, we present the case of a 62-year-old patient who developed agranulocytosis as well as hemolysis after a single administration of metamizole.
Conclusion:
This case illustrates the inherent allergic potential of metamizole and its effects on different hematopoietic cell types.
