Supportive Care Factors

Factor Value
Diarrhoea risk: Anti-diarrhoeals are usually prescribed with this treatment
Emetogenicity: Medium

Emetogenicity: Women 50 years and under should be considered high risk for oxaliplatin-induced nausea and vomiting, so antiemetic prophylaxis regimen should include an NK1 (e.g. aprepitant 125 mg day 1 and 80 mg days 2 and 3) based on trial evidence.
