Introduction: Mirtazapine is a noradrenergic and specific serotonergic antidepressant (NaSSA) and the previous reports show that may reduce nausea by inhibition of the serotonin 5-HT3receptor. Case report: A 38-year-old woman with advanced renal cancer with distant metastases was administered by sunitinib and oxycodone. Refractory nausea and vomiting developed during the course and mirtazapine at a daily dose of 1.875 mg was begun. The patient's nausea improved during the next day, and furthermore, by increasing the daily dose to 3.75 mg, vomiting was also improved on the third day. The therapy could be continued without withdrawal of sunitinib and oxycodone due to digestive symptoms. Although somnolence might be induced at a daily dose of 15 mg, the present low-dose mirtazapine could improve digestive symptoms without somnolence. Conclusion: We conclude that low-dose mirtazapine is one effective option for refractory nausea and vomiting during administration of sunitinib and oxycodone.
