Supportive Care Factors

Factor Value
Diarrhoea risk: Anti-diarrhoeals are usually prescribed with this treatment
Emetogenicity: Medium to high
Hypersensitivity / Infusion related reaction risk: High - routine premedication recommended

Emetogenicity: Routine antiemetic premedication may not be required for continuous dosing of oral anti-cancer medicines with MEDIUM to HIGH emetic risk; an individualised approach is appropriate.
