Background: Dipyrone (metamizole) is widely used for perioperative pain management in countries where it is marketed. However, uncertainty exists concerning the safe use of this drug, specifically considering the rare adverse event of an agranulocytosis. Methods: As evidence from published studies was lacking, an expert panel developed recommendations for the perioperative use of dipyrone. After a formal, structured consensus process, the recommendations were approved by the involved medical societies. Results: The panel agreed that blood cell counts shall not be standard for short-term perioperative use in patients unless they are at risk for neutropenia. The medical staff shall be aware of the symptoms and course of action when agranulocytosis is suspected. Patients shall be informed about the risks and benefits of dipyrone and about potential alternatives. The expert group concluded that dipyrone has a relatively positive risk-benefit ratio compared to other non-opioid analgesics. The group strongly recommended educating patients about the symptoms of agranulocytosis if they have received dipyrone over several days and/or treatment is to be continued after discharge, because agranulocytosis can occur several days after discontinuation of metamizole. Further recommendations refer to the information of the physician taking over the patient’s care after discharge and the avoidance of re-exposure in patients having previously suffered from dipyrone-induced agranulocytosis. Conclusion: The group’s recommendations shall be communicated in order to raise medical staff’s and patients’ awareness of the appropriate use of dipyrone in the perioperative period.
