Medication Ordering Tip - Understanding Dose Rounding and Dose Banding

Pharmacy tips alert prescribers to common medication ordering challenges and solutions.

Dose Rounding and Banding


Challenge: When prescribing certain medications, or for certain age groups, clinicians may find limited options for specifying a medication dose and wonder what the constraints are about or how to overcome them if clinically justified.

  • Dose rounding may be imposed to ensure a that a practically measurable drug dose (considering equipment available to nursing) can be prepared and administered. Rounding constraints cannot be overridden, however choosing a different product/concentration may help.
