Formulary is an iPhone app that provides access to the guidelines and protocols for paediatric prescribing published by the pharmacy department of Our Lady's Children's Hospital in Crumlin. The app has been designed with an easy-to-use navigation system that helps users find the information they need. It contains four sections: Drug dosages, Guidelines & Protocols, General Information, and Parenteral nutrition.

The app is intended for healthcare professionals only and requires users to register to create a record of users that can help verify that any individual user is a medical professional if needed. The app is constantly updated with new drug information and guidelines, and all updates are automatically added to the app. A subscription is required to use Formulary, priced at €5.99 per year, and can be managed or disabled through the iTunes account settings.

Formulary is a useful tool for medical professionals looking for an easy-to-use and constantly updated resource for paediatric prescribing guidelines and protocols.
