Clinical excipient and dose review

Assessing order suitability for the actual patient.

Procedure

  1. Verify patient, age, weight where needed, route, prescribed dose and frequency. Clarify ambiguous instructions with the prescriber.
  2. Record known allergies/adverse reactions and the responsible ingredient. Distinguish allergy from intolerance, irritation or preference.
  3. Calculate excipient exposure from the maximum daily preparation amount. Consult current official warnings for age/route and concomitant products.
  4. Check units: concentration, dose and volume are different quantities. For C mg/mL and D mg, volume = D/C mL, only for the confirmed chemical and dose basis.
  5. If an excipient must change, reassess the complete new formula, uniformity, preservation and BUD. Do not retain old evidence as applicable without comparison.
  6. Document the decision, source and date. Free from a specified ingredient does not mean free from allergy risk.
Stop criterion

Dose, route or critical-excipient mismatch: no supply before clarification.
