A batch of the widely used diabetes and weight-loss medication Ozempic has been recalled in Canada after concerns about cracked glass in some cartridges. The recall, which involves Ozempic 1mg/3mL injection pens, was voluntarily issued by the manufacturer, Novo Nordisk Canada.
The affected lot number is RZFFE55, and the recall is being carried out across wholesalers and pharmacies nationwide, according to an official statement by the company. This move comes after Novo Nordisk flagged the potential safety risk linked to the damaged glass inside the injectable pen's cartridge.
Statement from the Company
In a note shared with CTV News, Novo Nordisk emphasized its commitment to patient safety, stating,
“Patient safety is our top priority at Novo Nordisk. We aim to produce and distribute high-quality products. We apologize for any inconvenience caused by this situation.”
They’ve also confirmed that Health Canada has been officially informed of the recall.
What Health Canada Says
The national health department has labelled the situation a "Type II recall", which means the risk of serious harm is considered low, but some mild or temporary side effects may occur if the medication is used. Type II recalls usually do not involve life-threatening dangers but still require attention from consumers and healthcare professionals.
What Should Ozempic Users Do?
If you're using Ozempic, check the lot number on your injection pen. If it matches RZFFE55, you should stop using the product immediately and contact your pharmacist or healthcare provider.
Health Canada is also urging people to report any unusual side effects they may have experienced after using the affected product.
Why This Recall Matters
Ozempic is not just a treatment for type 2 diabetes—it’s also frequently prescribed off-label for weight loss, making it highly popular and widely used. A recall of this nature can affect a large number of patients across the country who depend on the drug for daily health management. Although the company says the likelihood of harm is low, it is taking swift action to remove the defective batch from circulation.
How to Stay Safe
- Double-check your medication’s lot number: RZFFE55 is the one affected.
- Return the product to your pharmacy if your lot number matches.
- Consult with your healthcare provider for a replacement.
- Report any side effects to Health Canada through its official website.
