There is no single U.S. GLP-1 patent expiration date. This GLP-1 drug patent expiration tracker separates the five things that get mashed into one headline: listed patents, FDA exclusivity, Paragraph IV filings, FDA approval, and actual pharmacy availability. Three older GLP-1s already have approved U.S. generics. Semaglutide and tirzepatide have live Paragraph IV filings — and dates running into the 2040s.

Here's the part almost nobody tells you: Apotex says a proposed generic version of Ozempic has already received tentative FDA approval in the United States. It still isn't for sale, and the reason why is the whole story on this page.

Best for / Not for you

This page is for you when you need to:

• Look up patent and generic-entry milestones for a specific GLP-1 brand and form
• Understand why 2026, 2032, 2033, 2039, and 2041 all show up in articles about the same drug
• Tell the difference between "FDA approved it" and "you can buy it"
• Check a headline you just read against the actual government record

This page is not for you when you need:

• An exact day a generic will hit your pharmacy — nobody can give you that, including us
• A ruling on whether a patent is valid or being infringed
• Advice about your own prescription — that's a conversation with your clinician
• Availability outside the U.S. — see our generic semaglutide availability by country tracker
• Permission to treat a compounded drug as a generic — it isn't one, and we explain why below

What we actually verified

We checked:

• FDA Orange Book patent and exclusivity records at the product-number level
• The FDA landing page that labels the current Paragraph IV download “as of August 3, 2026”, plus the row data inside the file
• FDA's first-generic approval tables for exenatide and liraglutide products
• Separate company launch or product records for the older approved generics
• Novo Nordisk's Q2 2026 financial report filed on Form 6-K August 4, 2026, read in full
• Health Canada's approval announcements from April, May, and June 2026
• Federal court docket records and company announcements, each cited by date

We did not claim:

• An exact future generic launch date for any product
• That every approved generic is currently on a pharmacy shelf
• That any listed patent is valid, infringed, or legally blocking a specific company
• That a compounded medication is a generic
• That a foreign patent date applies in the United States

Company-stated vs. independently verified

That middle row matters. The tracker says “Apotex announced tentative approval” rather than turning a company release into an unqualified FDA claim. That is not a wording trick. It is the line between what the company says and what we independently attached to the record.

The RX Index is the independent GLP-1 decision resource that scores telehealth providers and treatment paths on clinical legitimacy, care quality, transparency, access, and cost, so readers can choose the path that fits their situation.

GLP-1 drug patent expiration tracker: status at a glance

Notice what that column is doing. It is showing you status, not a year. A year like "2033" tells you almost nothing on its own. "Paragraph IV filed, no approval" tells you exactly where a drug sits today.

One thing this tracker cannot do

We cannot tell you the exact day a generic GLP-1 will reach your pharmacy. Nobody can. Patent lawsuits, private settlements, FDA review times, factory capacity, and a company's own launch decision can all move that date — in either direction.

The FDA says the same thing about its own data. Its position is that patent and exclusivity dates give a rough estimate at best, and that generics are sometimes approved before every listed patent and exclusivity has expired.

We think that admission makes this tracker more useful, not less. Every page that hands you one confident year is quietly hiding four moving parts. We show you all of them, with the date we last checked each one. A countdown clock means this is the wrong site. The current truth and what would have to change are below.

Why is there no single GLP-1 patent expiration date?

A drug does not automatically go generic when one patent expires. Generic entry depends on four moving parts — patents, FDA exclusivity, litigation or settlement, and manufacturing and launch. The part that still blocks approval or sale is the one that matters most. This is why articles about the same drug print different years and several of them can be technically accurate.

Here are the four moving parts in plain English.

A patent is private property — the drugmaker's ownership of an invention. FDA exclusivity is something else entirely: a period where the government limits when a copy can be submitted or approved, regardless of who owns what. They are two different systems, and they routinely end on different dates.

Most people have never heard of clock #2. It can be the one that matters most.

We'll show you the clearest proof further down, in Canada, where the key active-ingredient patent was already listed as expired but separate data protection still ran until January 4, 2026.

The right treatment path isn't the same for everyone — it depends on your state, your insurance and formulary, whether you want an FDA-approved or compounded medication, your preferred treatment path (injection or oral), and your budget. Because a patent date can't resolve any of that for you, use The RX Index's Find My GLP-1 Path tool to see which treatment paths are actually open to you today, with source-verified pricing.

Which GLP-1 drugs already have FDA-approved generics?

Three do. The FDA approved the first generic referencing Byetta on November 19, 2024, the first referencing Victoza on December 23, 2024, and the first referencing Saxenda on August 27, 2025. All three are older GLP-1 medications — exenatide and liraglutide — not semaglutide or tirzepatide.

Most people are surprised by this. The GLP-1 generic era already started in the U.S. It just started with the drugs almost nobody is asking about.

These dates come from the FDA's own 2024 and 2025 first-generic approval tables. They are not estimates.

For the separate market check, Hikma announced the U.S. launch of its generic referencing Victoza in December 2024, Teva announced the launch of its generic referencing Saxenda in August 2025, and Amneal lists an approved exenatide injection in its portfolio. That is why the tracker does not stop at the FDA approval date.

Two things to be careful about here.

First, Victoza and Saxenda are not interchangeable. They both contain liraglutide, but they are separate FDA products with separate approvals. A generic referencing Victoza is approved for diabetes. A generic referencing Saxenda is approved for weight management. Same molecule, different rulebook rows.

Second — and this is the rule the whole page runs on — FDA approval does not prove the drug is at your pharmacy. The FDA states this itself in the same tables where it publishes these dates: an approved drug may not be available on or immediately after its approval date. Approval means FDA cleared the product for marketing. Someone still has to make it, ship it, and stock it.

So we track those as two separate fields. Approval date is one column. Verified retail availability is another. We will never merge them.

What did going generic actually do to the price?

Less than most people expect, at first. Optum Rx reports that the average list price of a first generic is often only 10–15% below the brand. Its cited U.S. review found declines of about 15–40% with 3–5 competitors and 60–90% with 10 or more. Health Canada says many generics there cost 45–90% less than the brand. The discount depends on competition, not on the day one patent expired.

This is the most important section on this page, because it answers the question underneath the question. Nobody types "patent expiration tracker" because they enjoy patent law. They type it because they want to know when this stops costing so much.

Here is the honest answer, built from what has already happened rather than what anyone predicts.

The official numbers that look like a contradiction

All three can be true. They're measuring different markets and different stages of competition. The first entrant usually starts the price fight. A crowded market is what drives the deeper cut.

That means the date you're waiting for isn't the finish line. It's the starting gun. The real savings deepen only when enough companies actually make and sell competing products.

What happened to the GLP-1s that already went generic

We pulled this from Novo Nordisk's Q2 2026 financial report filed with the SEC on August 4, 2026. A company reporting its own losses to securities regulators is about as reliable as evidence gets — nobody overstates their own sales decline.

Read that last row again. Novo Nordisk is telling investors, in writing, that Canadian prices came down while sales volume stayed broadly stable. That is what generic competition does when it works.

But here's what generic liraglutide actually costs you today

This is the part that will save some readers a year of false hope. A generic GLP-1 has been on the U.S. market since 2024. It is still not automatically cheap.

These are cash or discount prices, not guaranteed insurance copays. Quantity, pharmacy, location, stock, and eligibility can change the number.

Real savings — $372.45 for generic Saxenda against $1,324.03 for the brand is roughly 72% lower in the same GoodRx snapshot. But "generic" did not mean four dollars at Walmart. It meant hundreds of dollars instead of more than a thousand in that comparison.

If you are budgeting your next few years around a generic semaglutide that suddenly costs $30, please plan differently. We'd rather tell you now than let you find out in 2032.

What actually changes your cost in the next 12 months isn't a patent date. It's your plan's formulary, manufacturer self-pay pricing, and whether you qualify for the Medicare GLP-1 Bridge. We track all three, with dates, in our GLP-1 price and access tracker.

When could generic Ozempic, Wegovy, or Rybelsus arrive?

No U.S. launch date is established for any semaglutide product. The FDA landing page labels its current Paragraph IV download “as of August 3, 2026,” and the rows show challenges filed against every major semaglutide brand. Apotex has also announced tentative FDA approval for a proposed generic Ozempic injection. Tentative approval is a real milestone, but it is not final approval and does not allow ordinary pharmacy sale.

Let's go product by product, using the FDA's own Paragraph IV Certifications List.

A Paragraph IV certification is a formal statement filed by a generic company saying, in effect: we believe your patent is invalid, unenforceable, or that our product wouldn't infringe it, so approve us anyway. It's the legal starting pistol for a generic challenge.

Semaglutide: the current Paragraph IV record

Source: FDA Paragraph IV Certifications List. The FDA landing page labels the download “as of August 3, 2026.” Counts are applications in the FDA row, not a deduplicated company count.

Now look at what those rows show when you place them together.

Ozempic and Wegovy contain the same active ingredient. Their last qualifying patents in these Paragraph IV rows are 2,798 days apart — Ozempic's at June 21, 2033, Wegovy's at February 17, 2041. That's a gap of 7 years and 8 months. They are still different FDA products with different doses, devices, and approved uses. They are not identical medicine in a different box.

And the largest Ozempic row shows seven potential first-applicant ANDAs. Standard Wegovy shows one. We can't tell you why from the public record, but that's a striking split worth watching. We also cannot turn those row counts into a reliable count of unique companies.

A date pattern we computed from the FDA record

Look at Ozempic's first Paragraph IV date: December 6, 2021.

Ozempic was approved December 5, 2017. Under U.S. law, a new chemical entity gets five years of exclusivity, but a generic company may file a Paragraph IV challenge after four years — a point the industry calls NCE-1. Four years after December 5, 2017 was December 5, 2021.

December 5, 2021 was a Sunday.

The first challenge is dated Monday, December 6, 2021 — one day after the four-year date and the first business day after it.

That timing strongly suggests generic applicants were ready to file as soon as the window opened. Hold that thought, because the tirzepatide section below shows the same pattern in an even more dramatic form.

What the Apotex announcement means

Apotex announced on April 10, 2026 that its semaglutide injection application had received tentative FDA approval — which it described as the first for a generic version of Ozempic in the United States.

That is genuinely significant. It means the application moved beyond filing and reached a tentative approval decision.

It also means almost nothing for your pharmacy in 2026.

Tentative approval means final approval is delayed because a patent or exclusivity still blocks it. The product cannot be marketed under that tentative approval. You cannot fill it.

We are publishing this as Apotex announced rather than as a flat FDA fact because the proof attached here is the company's April 10 release, not a linked FDA approval letter. The FDA Paragraph IV record independently confirms that an Ozempic challenge exists. It does not, by itself, prove tentative approval.

One more filing worth watching

Novo Nordisk's August 4, 2026 securities filing discloses that Cipla notified Novo Nordisk that it filed a U.S. application for a generic Ozempic with Paragraph IV certifications, and Novo sued Cipla for patent infringement in federal court in New Jersey.

The same filing says that on June 30, 2026, Sandoz sued Novo Nordisk in the Unified Patent Court in Milan, asking the court to cancel a European patent covering the 1 mg semaglutide dose for diabetes across 18 EU countries.

Neither event means a cheaper U.S. drug is coming soon. Both mean the fight has actually started.

When could generic Mounjaro or Zepbound arrive?

No U.S. launch date is established for either. But something notable happened in 2026: FDA records show the first Paragraph IV filings against both Mounjaro and Zepbound are dated May 13, 2026 — the exact day the four-year filing point arrived — and 85 days later, on August 6, Lilly filed 14 patent complaints against generic challengers in Delaware federal court.

This is the clearest example on the whole page of the gap between "you may file" and "you may sell."

Tirzepatide: the current Paragraph IV record

Source: FDA Paragraph IV Certifications List. The FDA landing page labels the download “as of August 3, 2026.”

The May 13 finding

Mounjaro was approved May 13, 2022. Four years later — the NCE-1 point for tirzepatide — was May 13, 2026. A Wednesday. A business day.

The first filings are dated May 13, 2026. Not a day later. Zero days after the four-year point.

With semaglutide, the first recorded challenge came on the first business day after the four-year date. With tirzepatide, the filings came on the literal date. And the FDA did not show one potential first applicant — it showed 13 potential first-applicant ANDAs on the largest Mounjaro rows and 12 on Zepbound's.

Lilly told investors in its August 5 quarterly filing that it had received Paragraph IV notices during July. On August 6, 2026, docket records show Lilly filed 14 complaints in Delaware federal court. The Sandoz case alone lists ten patents and a statutory stay deadline of November 13, 2029. That date is 7.5 years after Mounjaro's May 13, 2022 approval, reflecting the special NCE-1 rule for a timely suit filed after a Paragraph IV application submitted between years four and five.

That sequence — first legal date → a dozen-plus row-level first-applicant counts → 14 complaints in 85 days — is the entire lesson of this page compressed into one summer. The generic industry is ready. The legal wall is not down.

Do not add these numbers together

This matters and almost every write-up gets it wrong.

Those counts are per FDA row, not per company. The same manufacturer can appear on the 2.5 mg row, the 7.5 mg row, and the 15 mg row. Adding 13 + 13 + 12 does not give you 38 companies. It gives you a meaningless number.

We keep every strength row separate in the dataset, and we will never publish a summed manufacturer total, because the FDA field doesn't support one.

A realistic read for a patient: tirzepatide's compound patent is listed to May 13, 2036 — 3,555 days, or about 9.7 years, from this update. That is not a guaranteed launch date. Even if a challenger wins or settles earlier, FDA status, manufacturing, and launch still have to line up. If your plan for affording Zepbound is "wait for the generic," you need a different plan for the next several years.

If that's you, don't guess your way through it. See which GLP-1 treatment paths are open to you right now → The tool checks your state, your coverage, and whether you want an FDA-approved or compounded medication, then shows you what it actually costs. It takes about two minutes, and no purchase is required to use it.

Why does Canada already have generic Ozempic?

Because Canada's clocks ended earlier — and not in the order most people assume. Novo Nordisk's key Canadian active-ingredient patent was already listed as expired, while Health Canada's separate data-protection register ran until January 4, 2026. Health Canada approved the first generic semaglutide on April 28, 2026, becoming the first G7 country to do so.

This is the single best proof that a patent is not the only thing standing between you and a cheaper drug.

Here's the verified timeline:

That 13-day approval-to-launch interval is a useful real-world number. It shows that a product can move fast once the legal, regulatory, and manufacturing pieces are all ready. It does not tell us how fast any U.S. product will move.

One more detail worth watching: Health Canada's public queue moved from eight other applications under review on April 28, to seven on May 1, to six on June 29. That is a dated sequence, not a prediction. We keep the current country-by-country count in our generic semaglutide availability tracker.

Can I buy the Canadian generic from the U.S.?

Don't plan on it.

The FDA says that, in most circumstances, it is illegal for an individual to import a prescription drug that is not approved in the United States. FDA has narrow enforcement-discretion policies and separate government importation pathways, but neither turns a Canadian online order into routine U.S. pharmacy access. A product approved by Health Canada is not an FDA-approved product for U.S. purposes.

For the full country-by-country picture — India, Brazil, China, Canada, and other markets — use our generic semaglutide availability by country tracker.

What do the dates in this tracker actually mean?

Each date answers a different question. A patent date describes one listed patent. Exclusivity describes an FDA approval restriction. A Paragraph IV date marks a legal challenge. Tentative approval, final approval, first commercial marketing, and verified pharmacy availability are four more separate events.

Seven milestones can appear in a record. Not every product hits all seven, and they do not always happen in this exact order. The point is that none of them means the same thing.

1. Listed patent expiration. The date the brand company submitted to the FDA for a patent it listed, including any extension shown in the record. It is not a generic launch date. The FDA publishes what the company submits; the listing is not an FDA ruling that the patent is valid or infringed.

2. FDA exclusivity. A separate government block that can limit submission or approval of a copy. It runs on its own schedule. It can outlast a patent or end first.

3. Paragraph IV certification filed. A generic company has formally challenged at least one listed patent. This is a filing, not a win.

4. Tentative approval. The FDA has made a tentative approval decision, but a patent or exclusivity still blocks final approval. The product cannot be marketed under tentative approval.

5. Final approval. The FDA has cleared it for marketing. That still doesn't prove it is in stock anywhere.

6. First commercial marketing. The company actually started selling it. This can happen after approval, and the interval varies.

7. Verified retail availability. Someone confirmed you can actually get it filled. This is our own verification layer, not an FDA status. We report it separately and label it as ours.

When you read "the patent expires in 2033," you are looking at only one of up to seven milestones.

Can a generic be approved before the last patent expires?

Yes. It happens. A Paragraph IV certification lets a generic company seek approval before listed patents expire by arguing they're invalid, unenforceable, or not infringed. Litigation, settlements, and the specific scope of each patent can all change the sequence, which is exactly why the latest date in a patent table cannot be treated as an automatic launch date.

Here's how the machinery usually works, in three steps.

Step 1 — the filing. A generic company submits its application with a Paragraph IV certification saying at least one listed patent is invalid, unenforceable, or wouldn't be infringed by its version.

Step 2 — the notice. The brand company and patent holder get formal notice. They generally have 45 days after receiving it to sue.

Step 3 — the stay. If they sue in time, final FDA approval is generally postponed for 30 months from receipt of the notice while the case plays out — unless a court decision or another listed event shortens, extends, or ends the stay. There is a special NCE-1 rule: when the application is submitted between years four and five of new-chemical-entity exclusivity and suit is filed during that period, the stay can be extended so 7.5 years have elapsed from the brand's approval date.

That is why the August 6, 2026 Lilly cases matter. They are not just legal paperwork. A timely suit can delay final approval, and each challenger can have a different notice date and stay deadline.

There's also a 180-day first-applicant reward. The first substantially complete applicant or applicants with a qualifying Paragraph IV certification may earn 180-day exclusivity that can delay approval of some later ANDAs. Multiple first applicants can share it, and an authorized generic is treated differently. It is not safe to translate the rule into “one company will be the only generic seller for exactly 180 days.”

Why some fields in our tables are blank

For records after 2019, a blank approval or marketing field in the FDA's Paragraph IV data means the event has not happened or the determination has not been made. It does not mean a secret approval. It does not mean permanently blocked.

We leave blanks blank. Filling them in with a guess is how bad patent articles get written.

Why does the same GLP-1 show five different expiration years?

Because one drug can appear across several brands, FDA applications, product numbers, strengths, forms, indications, and patent categories — each with its own date. A single brand-level year hides all of that, which is why this tracker keeps the FDA application and product scope visible next to every date.

Walk down the ladder and you'll see where the confusion comes from:

• A drug is not a brand. Semaglutide is Ozempic and Wegovy and Rybelsus.
• A brand is not an application. Injectable and oral versions can sit under different FDA applications.
• An application is not a product. The FDA assigns separate product numbers and strength groups to different doses, containers, and devices. Mounjaro's autoinjector and KwikPen appear in separate rows.
• A patent is not one kind of thing. A drug-substance patent covers the molecule. A drug-product patent can cover the formula or device. A use patent covers a specific approved use. A use patent can run years past a molecule patent and cover a narrower slice.
• Some patents are being removed. When a company requests that a patent be delisted, it can still appear in FDA data for legal reasons. We flag those rows instead of silently counting them as ordinary protection.
• Pediatric exclusivity can add six months. It attaches to an existing patent or exclusivity rather than standing alone, which is why some records show a base date and a later protected date.

The 10-question test for any patent headline

Next time you see "Ozempic patent expires in [year]," run this:

1. Which country?
2. Which brand?
3. Which FDA application number?
4. Which product or strength?
5. Which patent category — substance, product, device, or use?
6. Does the date include an extension or pediatric exclusivity?
7. Is there a Paragraph IV filing?
8. Is there a tentative approval?
9. Is there a final approval?
10. Has anyone confirmed it's actually in pharmacies?

An article that cannot answer those questions has not earned a confident launch year.

Trulicity is the one that will never have a generic

Trulicity (dulaglutide) is a biologic, not a conventional drug. It was approved under Biologics License Application 125469 and appears in the FDA's Purple Book rather than the Orange Book, so follow-on versions would be biosimilars — not generics. Its original FDA approval date was September 18, 2014.

This trips up a lot of otherwise good articles, and it works in the other direction too — several pages claim semaglutide and tirzepatide need biosimilars. They don't. FDA treats semaglutide, tirzepatide, liraglutide, exenatide, and orforglipron as drugs under NDAs, and the Paragraph IV records show the generic pathway in use.

So when someone asks "when does Trulicity go generic," the technically correct answer is: it doesn't. It may eventually have biosimilars, which is a different pathway with different rules.

A simple 12-year calculation from September 18, 2014 lands on September 18, 2026. But the current Purple Book does not publish that date as Trulicity's verified reference-product exclusivity end date. The public FDA product record shows the original approval date and BLA pathway, but the exclusivity-expiration field is not populated. Patents and any other applicable protection are separate.

So this tracker does not turn September 18, 2026 into a countdown. Arithmetic is not the same thing as an FDA-posted status. As of August 19, 2026, the Purple Book shows no FDA-licensed dulaglutide biosimilar. We will log a real approval when the FDA publishes one, not when a calendar reaches a date we computed ourselves.

Is compounded semaglutide or tirzepatide a generic?

No. FDA-approved generics and compounded drugs are two different categories under U.S. law. A generic goes through an FDA application process and must meet FDA requirements before approval. A compounded drug is not FDA-approved as a finished product — the FDA does not review it for safety, effectiveness, or quality before it's sold.

We're including this section because it's the most common way people get misled on this exact topic, and because we will not let a compounded product appear anywhere in this tracker's generic-status columns.

How to recognize a real FDA-approved generic. You should be able to find all of these:

• An FDA application number
• An FDA approval record you can look up
• A named applicant company
• The reference brand it copies
• The approved strength and form

If you can't find those, it isn't a generic. It's something else.

Phrases that should make you pause:

• "Generic Ozempic" with no FDA record behind it
• "Same as Ozempic"
• "FDA-approved pharmacy" used in a way that implies the medication itself is FDA-approved
• A telehealth brand name presented as if it were the drug manufacturer

None of this means compounded medication is illegitimate or that people using it are making a mistake. Compounding is a real, regulated practice with real clinical uses. It is simply not the same category as an approved generic, and any page that blurs the two is doing you a disservice.

Our own count is simple: zero compounded products appear in any generic-approval row in this tracker. That is a decision rule, not a judgment about an individual prescription.

For the full explanation of how these categories differ, use our guide to GLP-1 biosimilars vs. generics.

What changed recently

This is the part a static patent table can't give you. Newest first.

What happens next

Dated, with what each date does and does not prove.

One note on that January 2027 row, because readers mix these up constantly: a price cut is not a patent event. Novo chose to lower its list price. No patent expired to make that happen. It's on this calendar precisely because it may move your cost sooner than any patent on this page.

What can I do if I can't wait for a generic?

Don't start, stop, or switch a prescription because of a projected patent date. Semaglutide's compound-patent date is more than five years away, and tirzepatide's is about 9.7 years away. Neither one is a guaranteed generic launch date. What can move your cost in the next year is your plan's formulary, manufacturer self-pay pricing, appeals, and program eligibility.

Here's the honest framing. For the overwhelming majority of people reading this page, waiting is not a plan. Five years is a long time to pay full price while hoping.

That doesn't mean you're stuck. It means the lever you're reaching for is the wrong one.

Things that can change your cost this year:

• Your plan's formulary and prior-authorization rules, which can change at renewal and sometimes mid-year
• Manufacturer self-pay pricing, which has moved several times in the last 18 months
• Medicare GLP-1 Bridge eligibility, for eligible Part D beneficiaries seeking Foundayo, any Wegovy formulation, or Zepbound KwikPen for weight management
• An appeal after a denial — check the written denial for the reason, deadline, and appeal route
• A clinician-reviewed decision between FDA-approved and compounded treatment paths, which has real trade-offs in both directions and should never be treated as a simple price swap

Things that will not change your cost this year: any patent date on this page.

Decide whether waiting is realistic for you

Run this quick check:

• Do I need treatment now, or can it genuinely wait years?
• Is the milestone I'm counting on only a patent date, or is there an actual approval?
• Has anyone confirmed a product is being sold, not just approved?
• Is my drug's date inside five years, or beyond it?

If you answered "I need something now" to the first one, the patent calendar isn't your answer.

How we built and verified this tracker

We join FDA product, patent, exclusivity, Paragraph IV, approval, and marketing records using application and product identifiers — not by matching brand names. We keep the application, product scope, source date, and plain-English meaning visible where the source provides them, so another researcher can reproduce the key results or tell us we're wrong.

Our source order

1. FDA Orange Book product, patent, and exclusivity files
2. FDA Paragraph IV Certifications List, using the date label on FDA's landing page and checking the row data itself
3. Drugs@FDA approval records and approval letters
4. FDA first-generic approval reports
5. USPTO records for patent-term details
6. Court records for anything about litigation
7. Company securities filings and press releases for company-specific announcements
8. Pharmacy, manufacturer, and wholesaler checks for actual availability
9. Reputable secondary sources for context only — never as the deciding authority when a primary record exists

Rules we don't break

On joining data: match by application number first, keep the product number, keep the strength group, keep the form. Never merge oral and injectable products. Never merge a diabetes reference product with a weight-management one without labeling it.

On patents: keep the original date and any extended date separate. Flag delist requests. Identify whether each patent covers the substance, the product, a device, or a use. Never call the latest date "the generic date." Never publish an opinion on whether a patent is valid or infringed — that's a court's job, not ours.

On Paragraph IV rows: keep each strength group separate. Preserve the FDA's row-level counts. Never infer a unique company count from an ANDA count. Never add overlapping counts together. Leave blank fields blank. The FDA landing page labels the current download “as of August 3, 2026,” but visible page headers inside the PDF are inconsistent. We use the FDA page label for the download date and verify the published rows themselves.

On approvals: tentative approval is not final approval. Final approval is not commercial marketing. Commercial marketing is not nationwide pharmacy stock. Each gets its own field.

One thing we did that we haven't seen in a normal brand-level tracker

We ran the semaglutide and tirzepatide filing dates shown on this page against the four-year NCE-1 point. The two first-day patterns hold: Ozempic's record lands the first business day after the date, and the first Mounjaro and Zepbound records land on the date itself.

We also independently recomputed every date difference published on this page. The Ozempic-to-Wegovy qualifying-patent gap comes out to 2,798 days. May 13 to August 6, 2026 comes out to 85 days. The remaining-day counts use August 19, 2026 as day zero.

Frequently asked questions

Is there one GLP-1 patent expiration date?

No. Each drug can have several patents across several FDA products, plus separate exclusivity periods, filings, litigation, approvals, and launch milestones. A single year for a whole brand is always a simplification and can be misleading.

Is generic Ozempic available in the United States right now?

No U.S. generic Ozempic is established as available for sale. Apotex announced tentative FDA approval in April 2026. Tentative approval is not final approval and does not allow marketing.

When does the Ozempic patent expire?

There isn't one answer without specifying which product and which patent. Ozempic's compound patent is listed to December 5, 2031. FDA Paragraph IV rows show last qualifying patents of February 1, 2032 or June 21, 2033 depending on the strength group.

When does the Wegovy patent expire?

The Paragraph IV record for standard Wegovy and Wegovy HD shows a last qualifying patent of February 17, 2041. Oral Wegovy sits under a separate application and shows February 1, 2039. Those are patent-record dates, not launch dates.

When does the Mounjaro or Zepbound patent expire?

Tirzepatide's compound patent is listed to May 13, 2036. FDA records show last qualifying patents of December 30, 2041 for Mounjaro rows and July 22, 2039 for Zepbound rows. Lilly filed 14 related Delaware complaints on August 6, 2026.

Why do some articles say a semaglutide patent expired in 2026?

They may be talking about another country. Novo Nordisk reported that India's semaglutide compound patent expired March 20, 2026. Canada reached generic entry in 2026 under its own patent and data-protection history. Neither fact creates a U.S. generic.

What is a Paragraph IV certification?

It's a formal statement filed by a generic applicant saying a listed patent is invalid, unenforceable, or wouldn't be infringed by its product. It starts a legal challenge. It is not an approval and it is not a launch.

Does a Paragraph IV filing mean a generic was approved?

No. It means an application was filed with a specific type of patent challenge attached. Approval is a separate later step, and timely litigation can delay final approval.

What does tentative FDA approval mean?

It means the FDA has made a tentative approval decision, but a patent or exclusivity period still blocks final approval. The product cannot be marketed under that tentative approval.

Can a generic be approved before the last patent expires?

Sometimes. Paragraph IV challenges, court rulings, settlements, authorized generics, and the exact scope of each patent can all change the order. This is one reason the latest date in a patent table isn't a reliable launch date.

Does FDA approval mean the generic is in pharmacies?

No. The FDA states that an approved drug may not be available on or immediately after its approval date. Manufacturing, distribution, and stocking are separate events.

How much cheaper will generic GLP-1s be?

Nobody can give one percentage. Optum Rx says the first generic is often only 10–15% below brand list price, while markets with 10 or more competitors have shown 60–90% declines. In the August 19 price snapshot, GoodRx showed $372.45 for generic Saxenda and $1,324.03 for brand Saxenda at the listed quantities, while 6 mL of generic liraglutide was $402.26–$441.53 cash on Drugs.com.

Is compounded semaglutide a generic?

No. Compounded drugs are not FDA-approved finished products and are a separate category from FDA-approved generics under U.S. law. They should never be listed with generic approval status.

Why does Canada have generic Ozempic before the United States?

Different patents and different exclusivity rules. Canada's key active-ingredient patent was already listed as expired, while separate data protection ran to January 4, 2026. Health Canada approved the first generic semaglutide on April 28, 2026.

Will Trulicity have a generic?

No conventional generic. Trulicity is a biologic, so a follow-on version would use the biosimilar pathway. Its original BLA was approved September 18, 2014, but the current Purple Book does not publish a verified Trulicity reference-product exclusivity end date, and no dulaglutide biosimilar is approved as of August 19, 2026.

How often is this tracker updated?

Patent and exclusivity files are checked monthly against FDA data releases. Paragraph IV, approval, and major litigation records are checked weekly. Material changes are published with a date and logged in the change table above.
