A Case of Anaphylactic Shock after First Administration of Oxaliplatin

: A 48-year-old woman with advanced gastric cancer with peritoneal dissemination was treated with weekly paclitaxel from October 2015 and was then administered the CapeOX regimen. Although she had no adverse event during the 2-hour administration of the first oxaliplatin(L-OHP), sudden wheezing, subsequent decrease in blood pressure, and vomiting occurred after completing the administration. After intravenous injection of epinephrine(1mg)and drip infusion of methylprednisolone( 500mg), she received continuous administration of norepinephrine for 5 days. Hypersensitivity reaction to LOHP typically occurs after several cycles and within 30 minutes of starting the administration. However, we have to recognize that the hypersensitivity can also occur after the first cycle and at a later onset.
