Notice: Prescription Drug List (PDL): Human and Veterinary Antimicrobials

November 30, 2018
Our file number: 18-118591-617

The purpose of this Notice of Amendment is to notify that Health Canada has amended 14 antimicrobial active ingredients or their salts or derivatives from non-prescription to prescription on the Veterinary Prescription Drug List (PDL). These amendments include adding antimicrobial classes, listing certain antimicrobials as derivatives rather than as antibiotic classes, and deleting qualifiers that are no longer necessary.

Additionally, the Human PDL has been amended to specifically list the derivatives of Erythromycin and Lincomycin, and to delete the Erythromycin derivative, Tulathromycin, which is only used in veterinary medicine. These amendments are effective as of December 1, 2018.

The revised listings are provided in the tables below.

Rationale:

Products for Human Use:

As noted in the Notice of Intent to Amend, the changes to the "Products for Human Use" part of the PDL are to correct inaccuracies (See Table 1a and 1b).

Products for Veterinary Use:

As noted in the Notice of Intent to Amend, the changes to the "Products for Veterinary Use" part of the PDL are to strengthen veterinary oversight and promote the prudent use of medically-important antimicrobials in animals (See Table 2a-2d).
Products for Human and Veterinary Use:

In addition to the revisions proposed in the Notice of Consultation, there are two additional revisions to the PDL. Specifically, for both the human and veterinary listings, a Carbapenem category is added and the individually listed carbapenems were removed (See Table 1c and 2e).

In addition, multiple ingredients are included in the Cephalosporins category of the human and veterinary listings under the "Including (but not limited to)" section (See Tables 1d and 2f). Several ingredients belonging to this category that were in recent years approved for veterinary use and previously for human use, were not included as specific examples; they are now included in both lists for clarity purposes. These products are already sold under prescription status and are labelled as such.
