Is Vasopressin legal in Canada?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Yes. Vasopressin is an approved medicine in Canada. Its legal category is "Health Canada approved, prescription only". The approval covers the use on its label. It is given out on prescription, not sold over the counter. Products labeled "research use only" are not covered by that approval, and that label does not make them legal to use in people. On the evidence, 1 completed human trial is cited on its profile.

Legal category
Health Canada approved, prescription only
Health Canada authorisation and DIN status, from the Vasopressin profile.
Reviewed Sep 2026. This is a legal category, not legal advice.
A "research use only" label on a vial does not make it legal to use on people.

What this means
- 01
Health Canada has approved Vasopressin for at least one use named on its label. So a proper pharmacy-grade product exists in Canada, and pharmacies hand it out on prescription.
- 02
Approval covers only the uses named on the label. Any other use is a prescriber's call. The approval itself does not cover it.
- 03
Unlicensed vials sold online, including those labeled "research use only", are not the approved product. The approval does not cover them.
What Vasopressin is
The natural hormone that makes you hold on to water. As a drug, it is FDA-approved to raise blood pressure in very sick patients.
Vasopressin, also called antidiuretic hormone, controls how much water your body keeps. It works on the kidneys to make urine more concentrated.
How it works: It switches on V2 receptors in the kidney, which makes the body keep water. It switches on V1 receptors on blood vessels, which raises blood pressure.
Approval history: FDA-approved (Vasostrict) to raise dangerously low blood pressure in a type of shock (vasodilatory shock)
How Health Canada treats this kind of product
Allows a drug to be sold by issuing a Notice of Compliance and a Drug Identification Number (DIN). A compound that is not allowed for sale cannot legally be sold for use in people. Bringing in prescription drugs for your own use is also limited.
The legal category above is how The Longevity Archive reads Health Canada, Health Products and Food Branch listings for Vasopressin on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.
Vasopressin in sport and the military
Whether Vasopressin is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in Canada. Before you compete or get tested, look up Vasopressin by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
