Update for practices March 2023

We have a quick update for you regarding recent changes to penicillin product withholding periods as well as a webinar on our Dry Cow Therapy Statement.

Penicillin product withholding period reassessments

As part of the Ministry for Primary Industries and Agricultural Compounds and Veterinary Medicines (ACVM) antimicrobial resistance reassessment review, pharmaceutical companies have been asked to review and update their labels regarding appropriate dose rates for clinical disease indications, where penicillin is an antimicrobial of choice.

The most common change has been an increase in dose rate. The higher levels of antibiotic being administered means that withholding periods (WHP) need to be adjusted to ensure maximum residue levels (MRLs) are being complied with.

MPI has created a table of the 69 penicillin products that lists dose rates and WHPs, and highlights any changes. There is also a set of FAQs which we encourage you to read and share amongst your team.

Details about the review can be found here .

DCAT Statement webinar

The Veterinary Council of New Zealand (VCNZ) and the Dairy Cattle Veterinarians (DCV) branch of the NZVA are running a webinar to discuss the recent VCNZ Statement on the Authorisation of Dry Cow Therapy.

Based on feedback from the profession, VCNZ and DCV have put together guidance to address the concerns, including scenarios and recommendations on how to use the published information to address common and practical prescribing concerns. The guidance will be available early next week.
