What is a Drug Identification Number (DIN)?
A Drug Identification Number (DIN) is a computer-generated, eight-digit number issued by Health Canada to authorize a drug product for sale in Canada. This number is a crucial identifier that confirms the product has been evaluated and approved for use. A DIN is a confirmation that the drug meets stringent health and safety standards regarding its formulation, labeling, and manufacturing processes. It is required for all authorized prescription and over-the-counter drugs sold in Canada. The DIN uniquely identifies several key characteristics of the product, including:
- Manufacturer: The company responsible for the drug, which is Novo Nordisk Canada Inc. for Wegovy.
- Product Name: The brand name, in this case, WEGOVY®.
- Active Ingredient(s): Semaglutide.
- Strength(s): The concentration of the active ingredient.
- Pharmaceutical Form: Such as a pre-filled pen for subcutaneous injection.
- Route of Administration: For Wegovy, this is subcutaneous injection.
The DINs for Wegovy in Canada
Because Wegovy is available in different dose strengths for the weekly injection, each specific dose is assigned a unique DIN. These numbers allow for precise identification and tracking within the healthcare system, from the manufacturer to the patient. The following is a list of the DINs for the single-use, pre-filled Wegovy pens available in Canada, as approved by Health Canada:
- 0.25 mg dose: The DIN is 02522551.
- 0.5 mg dose: The DIN is 02522578.
- 1.0 mg dose: The DIN is 02522586.
- 1.7 mg dose: The DIN is 02522594.
- 2.4 mg dose: The DIN is 02522608.
This system ensures that healthcare providers can correctly prescribe and dispense the appropriate starting and maintenance doses of the medication during the patient's treatment plan.
Health Canada's Approval and the Significance of the DIN
Wegovy's path to approval in Canada began with a New Drug Submission (NDS) from the manufacturer, Novo Nordisk Canada Inc., which was authorized by Health Canada in November 2021. The authorization followed an extensive evaluation of clinical data, primarily from the STEP (Semaglutide Treatment Effect in People with Obesity) clinical trial program. The DINs are a key part of this authorization, signifying that the product's safety, efficacy, and quality have been rigorously assessed by the regulatory body.
The DIN serves several important functions:
- Consumer Protection: It assures patients that the product they are receiving is the genuine, authorized medication and not a counterfeit. Unauthorized drugs without a DIN are non-compliant with Canadian law and are not verified for safety.
- Market Monitoring: Health Canada uses the DIN system to monitor drugs on the market. This includes tracking sales, managing product recalls if necessary, and conducting inspections to ensure continued quality control.
- Claims and Coverage: Insurance companies and provincial drug plans use the DIN to verify drug products for coverage. Patients can provide the DIN to their insurer to check for plan benefits and coverage details.
How to Find Your Wegovy DIN
For patients, finding the DIN for their specific Wegovy prescription is straightforward. The DIN is typically found in a couple of key places:
- On the medication box: The eight-digit DIN will be clearly printed on the label of the Wegovy® packaging.
- On your pharmacy receipt: The DIN is also listed on the official pharmacy receipt provided with your prescription.
If you cannot locate the number, your dispensing pharmacy can provide it for you.

Conclusion
The Drug Identification Number (DIN) is an essential component of Canada's drug regulation system, providing a unique marker for every authorized drug product, including Wegovy. By assigning a distinct DIN to each dose strength, Health Canada ensures the safety, quality, and efficacy of the medication from manufacturing through to patient use. For patients and healthcare providers alike, knowing and understanding the DIN is crucial for confirming medication authenticity, managing prescriptions, and navigating insurance coverage. When starting or continuing Wegovy treatment, referring to the DIN on the packaging is the most reliable way to confirm the exact product and dose being used.
