The use of standard batch sheets ensure that consistent strengths of these products are prepared across all areas of the health sector to prevent medicine dosing errors occurring due to mix-ups. There have been several instances of overdoses and underdosing occurring due to confusion caused by different strengths being prepared by different pharmacies.
The standard batch sheets published here are created and maintained by the Compounding Working Group (CWG), a sub-committee of the Health Quality & Safety Commission Medication Safety Expert Advisory Group. They are based on the best available evidence from recent or robust published studies. In situations where such evidence is weak or unavailable the recommendations are based on current best practice from New Zealand or overseas.
Pharmacists using these batch sheets should be familiar with the content of the following documents:
- General guidance for compounding oral liquids - March 2019
This document addresses common questions about substituting bases, storage conditions, shelf-life and using different brands.
- Pharmacy Council Safety Alert – Caution Required with Compounded Oral Liquid Formulations – April 2019
This document provides recommendations to minimise risk of adverse events related to compounded oral preparations.
