Haematology regimens within the SACT Regimen Library currently only specify mandatory supportive care medicines to be used for all patients, unless contraindicated. A clinically equivalent mandatory medicine may be substituted as per institutional practice.

Supportive care factors are included in all regimens, with the appropriate dimensions (value) as Recommended (for most patients), Consider (for some patients after clinical risk assessment), or with guidance (e.g. emetogenicity classification or if variable). Centres are expected to include antiemetics and other supportive care medicines within their own prescribing systems.
