Is Mifepristone legal in Canada?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Yes. Mifepristone is an approved medicine in Canada, classified as "Health Canada approved, prescription only". Approval covers its labeled indication and it is supplied on prescription, not over the counter. Products labeled "research use only" fall outside that approval and the label does not make human use lawful. On the evidence, no human study is cited on its profile.

What this means
- 01
Health Canada has approved Mifepristone for at least one labeled indication, so a pharmaceutical-grade product exists in Canada and is dispensed on prescription.
- 02
Approval is indication-specific. Uses outside the label are a clinical decision for a prescriber, not something the approval itself authorizes.
- 03
Unlicensed online vials, including those labeled "research use only", are not the approved product and are not covered by the approval.
What Mifepristone is
Blocking cortisol signalling was a serious longevity hypothesis, because chronic glucocorticoid exposure damages muscle, bone and brain. The mouse lifespan test found nothing in either sex.
The reason anyone tested this is worth stating, because it is a good hypothesis. Cortisol rises with age, and sustained glucocorticoid exposure causes exactly the changes that define ageing badly: muscle wasting, bone loss, visceral fat accumulation, insulin resistance, hippocampal atrophy and immune suppression.
Mechanism: A competitive antagonist at the glucocorticoid receptor, blocking cortisol's transcriptional effects, and at the progesterone receptor, which is the basis of its obstetric use. At the glucocorticoid receptor it prevents the catabolic signalling that drives muscle proteolysis, hepatic gluconeogenesis and adipose redistribution.
Regulatory history: FDA-approved as Korlym for hyperglycaemia secondary to hypercortisolism in Cushing's syndrome, and as Mifeprex for medical termination of pregnancy. Not approved for any ageing indication.
How Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for Mifepristone at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
