Supporting risk-based prescribing in everyday practice
With growing expectations around responsible parasite control, there is more pressure than ever to show tailored, evidence-based prescribing decisions. Boehringer Ingelheim is here to support your whole practice team as you embed this approach.
Responsible use and risk assessment
To help you bring responsible prescribing into everyday practice, we created Parassess®: a fast, structured way for owners to understand their pet’s individual risk. This online tool is based on ESCCAP guidelines and has been developed alongside leading parasitologists. It collects key lifestyle and behaviour information in just a few minutes and generates a personalised report for owners to discuss with you.
Practice Parassess® training
To build skills and confidence across the team, our practice Parassess® training helps you roll out Parassess® to pet owners and supports implementation of a protocol that works specifically in your practice.
