Medically Important Antimicrobials Restrictions

HCBC Staff
Created: May 4, 2018

Prescription required as of December 1, 2018

As of December 1, 2018, all Medically Important Antimicrobials (MIAs) will require a prescription from a veterinarian, and can only be dispensed by a veterinarian, licensed pharmacist, or as mixed medicated feed from a commercial feed mill.
These drugs will no longer be available for purchase at livestock medicine outlets, co-operatives, or other places where over-the-counter animal medications are currently sold.

Health Canada is implementing these changes in an effort to protect human health by limiting the opportunities in which antibiotic resistant organisms can emerge. The list of MIAs is based on antimicrobial categorization determined by Health Canada in relation to each drug’s importance to human medicine.

What are MIAs?
Some MIAs include:

Penicillin G
Streptomycin/ Dihydrostreptomycin
(or their salts or derivatives)
A strong veterinary-client relationship is an important piece of the puzzle in adapting to Health Canada’s restrictions on the purchase of Medically Important Antimicrobials (MIAs).

How do you prepare for these changes?
Develop a valid client-patient relationship with your veterinarian.
Hang the Canadian Animal Health Institute poster listing all MIAs and its corresponding cover letter in a visible, high traffic area within your facility.
Talk with local horse owners to be sure they are aware of these changes.
Consider developing a herd health plan with your veterinarian.
Ask questions of your local pharmacy.
What is a Veterinary Client-Patient Relationship?
A veterinary client-patient relationship (VCPR) is the relationship you establish with your veterinarian and the terms under which it operates, as evidenced by medical records. A strong VCPR is most important in areas where access to veterinary care is limited due to distance and remote access. By establishing a practice of relevant and timely interaction with the veterinarian, you are prepared in the event that a prescription is needed in a timely fashion.
