December 1 Deadline is Approaching: All MIAs for Veterinary Use Will Be Sold by Prescription Only

October 9, 2018

As you are aware, Health Canada is moving a number of Medically Important Antimicrobials (MIAs) approved for veterinary use before 2004 to the Prescription Drug List (PDL). With this change, Health Canada will establish the same level of oversight for those MIAs approved before 2004 as for those approved after.

As of December 1, 2018, all MIAs for veterinary use will be on the PDL and must be sold by prescription only.
