What this means
- 01
Health Canada has approved Desmopressin 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 Desmopressin is
An FDA-approved vasopressin analogue for diabetes insipidus, bedwetting, and certain bleeding disorders.
Desmopressin is a synthetic analogue of vasopressin selectively active at the kidney's water-retention receptor, without the blood-pressure effect. It is FDA-approved for central diabetes insipidus, nighttime bedwetting, and to boost clotting factors in mild hemophilia and von Willebrand disease.
Mechanism: Selectively activates V2 receptors to concentrate urine and release stored clotting factor VIII and von Willebrand factor.
Regulatory history: FDA-approved (DDAVP) for multiple indications
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 Desmopressin 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.
