Wegovy generic name: semaglutide, and why a real generic Wegovy exists in Canada but not in the US

The Wegovy generic name is semaglutide. That part takes one sentence. The follow up question, the one patients actually ask at the pharmacy counter or in a telehealth chat, is harder: if the generic name is semaglutide, can I just buy generic semaglutide? In September 2026 the honest answer depends on which country you are standing in and what the seller means by the word "generic," because that word is now used for three very different products.

The original element in this piece is a five question label check. It is a sequence you can run on any semaglutide product in front of you, a pen, a vial, a tablet, or a checkout page, to sort it into one of five categories: brand Wegovy, a sibling brand of the same molecule, a regulator approved generic, a compounded preparation, or a product with no approval at all. We have not seen this sorting laid out anywhere else, and it answers the real question behind the search.

One molecule, several brand names

Semaglutide is the nonproprietary name, the chemical identity of the drug. Novo Nordisk sells that same molecule under different brand names at different doses for different approved uses. Ozempic is a weekly injection for type 2 diabetes that climbs to a maximum of 2 mg. Wegovy is a weekly injection for chronic weight management that climbs through 0.25, 0.5, 1, and 1.7 mg to a 2.4 mg maintenance dose. Rybelsus is a daily tablet for type 2 diabetes. The Wegovy pill, a daily 25 mg oral semaglutide for weight management, was approved by the FDA in December 2025.

So when someone says Ozempic and Wegovy are "the same drug," they are right about the molecule and wrong about the product. The dose ladder, the pen, and the approved indication differ. The weight results everyone quotes, about 15 percent average loss over 68 weeks versus about 2.4 percent on placebo in the STEP 1 trial, came from the 2.4 mg dose, not the diabetes doses. That detail matters for the generics story below, because most of the generics approved so far copy Ozempic, not Wegovy.

Is there a generic Wegovy? Where the word "generic" is true in 2026

In Canada, yes. Health Canada approved its first generic semaglutide, a copy of Ozempic, on April 28, 2026, making Canada the first G7 country to do so. On June 29, 2026 it approved Sevmia from Apotex, which Health Canada describes as a generic version of Wegovy for once weekly chronic weight management in patients 12 and older. That is a true generic Wegovy: same active ingredient, reviewed by a national regulator against the brand, and cleared for the weight management indication. Health Canada said six more generic semaglutide submissions were still under review at the time.

In the United States, not yet, and the reason is patents rather than science. On April 10, 2026, Apotex announced that the FDA had granted tentative approval to its generic semaglutide injection, a copy of Ozempic. Tentative approval means the FDA has found the application meets its standards but cannot grant final approval yet because of patent or exclusivity protection. The product cannot legally be sold. Novo Nordisk's own annual report filed with the SEC lists US compound patent expiry for its semaglutide brands in 2032, and it holds later patents on formulations, dosing, and pens that generic makers will have to clear or litigate.

Here is the counterintuitive part patients miss: the first US generic in the pipeline copies Ozempic, and a generic Ozempic would not be approved for weight loss. A US patient with obesity and no diabetes who wanted a generic would still, on paper, be waiting for a generic Wegovy specifically.

The three things sold as "generic semaglutide" in the US right now

Because no final approved generic exists in US pharmacies, anything marketed to you today as generic semaglutide falls into one of three buckets.

The first is compounded semaglutide, made by a pharmacy rather than a drug manufacturer. The FDA states plainly that compounded drugs are not FDA approved and are not reviewed for safety, effectiveness, or quality, and it has received reports of adverse events, some requiring hospitalization, tied to dosing errors with compounded injectable semaglutide. We cover the tradeoffs in depth in our guide to compounded versus brand semaglutide.

The second is a salt form. The FDA notes that semaglutide sodium and semaglutide acetate are different active ingredients from the semaglutide base in the approved drugs. A label that reads "semaglutide sodium" is not the Wegovy generic name. It is a different chemical.

The third is the "research use only" vial. The FDA calls these illegally sold unapproved drugs, and it lists semaglutide among the ingredients it has found falsely labeled that way.

The five question label check

Run these in order. Stop at the first question that sorts the product.

Question one: does the name printed on the carton say Wegovy? If yes, and it came from a state licensed US pharmacy, it is the brand, and you are done.

Question two: does it say Ozempic or Rybelsus? Then it is brand semaglutide approved for type 2 diabetes. It is the same molecule but not the product studied for weight management at 2.4 mg, and your prescriber should be the one deciding if that swap makes sense.

Question three: does the active ingredient line read exactly "semaglutide," with no "sodium" or "acetate" after it, and does the package name a manufacturer and an approval, such as a Health Canada DIN? Then it may be a regulator approved generic. If it is a Canadian generic such as Sevmia, know that Canadian approval does not make it FDA approved.

Question four: does the label name a compounding pharmacy, a patient name, or a beyond use date instead of a manufacturer's expiration date? Then it is compounded. Ask the pharmacy which salt form it uses and whether it is a state licensed 503A or an FDA registered 503B outsourcing facility.

Question five: does it say "for research purposes," "not for human use," or give no pharmacy at all? Then it is outside every approval system. Do not inject it.

What the approvals do not tell you

A generic approval proves the copy matches the brand's active ingredient and performance standards. It does not tell you what a generic Wegovy will cost in the US, because none is priced yet. Health Canada says generics there often cost 45 to 90 percent less than the brand, but that range covers all generic drugs, not semaglutide specifically. And no approval so far tells you whether generic pens will match the brand's device, which is the part patients actually handle every week.

For most people, the practical cost question in 2026 is still coverage and savings programs rather than generics.
