Background
Lomustine is used as palliative therapy in patients with brain tumours, Hodgkin's Disease and other tumours.
Lomustine was previously marketed in Canada by Bristol Myers Squibb (BMS) under the brand name CeeNU in 10 mg and 40 mg capsules. BMS is no longer selling this drug in Canada.
What we're doing
We recognize the importance of lomustine.
We have allowed Septa Pharmaceuticals to import US-authorized lomustine in 10 mg and 40 capsules and UK-authorized lomustine in 40 mg capsules until December 2026. Visit the List of Drugs for Exceptional Importation and Sale for more details.
We're communicating with provincial and territorial governments and other stakeholders, such as the Brain Tumour Foundation of Canada, to coordinate the sharing of information about this drug. We're also working with manufacturers and stakeholders to identify strategies for continued access to lomustine for patients in Canada.
What you can do
Speak with your doctor or pharmacist if you have questions or concerns about the discontinuation of lomustine. They may be able to offer other options if your medicine is not available.
You should always:
- use a licensed pharmacy to get your medication
- only buy products that are authorized for sale in Canada
- avoid buying products from unlicensed and unverified online sellers, as these products may:
- not contain the active ingredient
- contain other undeclared and hazardous ingredients that could cause serious risks to health
- not meet manufacturing quality and safety standards, and have unknown contaminants
All drugs approved for sale in Canada have an 8-digit drug identification number (DIN). The DIN assures you that Health Canada has assessed a drug and considers it safe and effective when used as directed on the label. The DIN also provides a way to track adverse drug reactions.
Report any health product-related side effects or complaints to Health Canada.
