What this means
- 01
Health Canada has approved Cetrorelix 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 Cetrorelix is
An FDA-approved GnRH antagonist used in fertility treatment to prevent premature ovulation.
Cetrorelix is a GnRH antagonist that blocks the receptor directly, immediately suppressing LH and FSH without the initial flare seen with agonists. It is FDA-approved as Cetrotide in assisted reproduction to prevent premature ovulation during ovarian stimulation.
Mechanism: Competitively blocks GnRH receptors, producing immediate suppression of LH and FSH release.
Regulatory history: FDA-approved (Cetrotide)
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 Cetrorelix 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.
