Explains

PharmD, BCPS · Clinical pharmacist Updated

There is no expected month yet for generic simvastatin and sitagliptin phosphate. None is for sale yet.

Will the generic cost less?

Usually, and more so as more companies sell one. One company has applied to the FDA to make it. In the FDA’s study of past launches, pharmacies paid about 31% less once one company sold a generic. See the price pattern

What should I do now?

Keep taking Juvisync as prescribed. When a generic arrives, your pharmacy may switch you to it automatically, and it may look different. What a generic means for you

Our month is only an estimate based on available information, so we never name a day.

Juvisync’s Road to a Generic

Juvisync has had the market to itself since the FDA approved it in October 2011 (Merck Sharp And Dohme Corp). Its one listed patent runs to October 2026. Generic companies have challenged its patents with the FDA since June 2012.

One generic maker has filed an application with FDA. What opens the door, a ruling, a deal or an expiry, is not settled yet.

Each bar runs from the brand’s approval to the day that protection ends. The green band is our projection for the first generic: a month, never a day, because legal dates move and a generic reaches shelves days to weeks after it is allowed.

Juvisync Patents and FDA Protections

Every patent and exclusivity the FDA Orange Book lists for Juvisync’s own applications. A protection running past the expected month does not mean the date is wrong: a settlement or a court ruling can let a generic in before a patent ends, and a patent on one formulation or use does not block every generic.

Patent Challenges to Juvisync

The first patent challenge to Juvisync reached the FDA in June 2012, from one company on that first day. The FDA’s list has 3 entries for Juvisync, by form and strength. The FDA has not approved a first challenger’s generic yet.

What Is a Patent Challenge?

A generic company that wants to sell its version before Juvisync’s patents run out can tell the FDA that a patent is invalid, or that its version does not infringe it. The FDA calls this a “Paragraph IV certification.” The brand company usually sues, and the FDA then generally cannot approve that generic for up to 30 months while the case runs. To reward going first, the companies that challenge first can get a 180-day head start: the FDA cannot approve the generics that came after them until it ends.

Source: the FDA’s Paragraph IV Patent Certifications list, as of September 2026. The FDA began posting the 180-day decisions and the first challenger’s approval and first sale in June 2019: an older entry it has not updated since reads “Not posted”, and “Not yet” means the list records no such event. “Companies that day” is the FDA’s count of challenges that arrived on the first day.

Who Is Lined Up to Make Generic Simvastatin and Sitagliptin Phosphate

Three steps stand between a brand and a generic you can buy: a company applies to the FDA, the FDA approves it, and the company starts selling it.

1

Applied to the FDA

One company has applied to the FDA to make generic simvastatin and sitagliptin phosphate.

The FDA names a company only once it approves its application, even tentatively, and it has not done that for this one yet, so the company is not named here. Names often come out in the brand company’s patent lawsuits or in the companies’ own announcements.

First in line. One of them was first in line: the first company to challenge the brand’s patents can earn 180 days on the market before the other generics, which is why being first matters.

Generic companies have challenged Juvisync’s patents with the FDA since June 2012: see the patent challenges.

2

Approved by the FDA

Not yet. The FDA has not approved a generic simvastatin and sitagliptin phosphate. Final approval often comes close to the day a generic can be sold.

3

For Sale in Pharmacies

Not yet. No company lists a generic simvastatin and sitagliptin phosphate for sale with the FDA.

Sources: how many companies have applied, from court records and company announcements; approved generics from the FDA Orange Book; tentative approvals from Drugs@FDA; what is for sale from the FDA NDC Directory. The FDA does not disclose an application before it approves it (21 CFR 314.430).

Juvisync Price: What Pharmacies Pay and What Generics Usually Do

What a Generic Could Cost

How we estimate it. The national survey of what pharmacies pay (NADAC) has no recent price for Juvisync, so we cannot show dollars. Here is the FDA’s finding of how far the price pharmacies pay usually falls as generic companies join: about 31% with one company, 44% with two, 73% with four and over 95% with six or more (the typical drop for every drug whose first generic came out from 2015 to 2017).

Median prices pharmacies paid for the generic (invoice prices), compared with the brand’s price before generic entry, from FDA’s 2019 analysis “Generic Competition and Drug Prices”. At the manufacturer’s price FDA found steeper drops (about 39%, 54%, 79% and over 95%), the figures quoted elsewhere on this tracker. A typical pattern, not a price quote for this medicine.

What a Generic Juvisync Means for You

Nothing Changes Until It Is in Pharmacies

Until a generic is actually for sale, keep filling Juvisync as usual. When one arrives, there is nothing you need to sign up for.

Your Pharmacy May Switch You Automatically

Every state lets pharmacists fill a brand-name prescription with an FDA-approved generic rated as equivalent to it, and about 19 states require them to, unless your prescriber writes “dispense as written” or “brand medically necessary” on the prescription. Some states ask the pharmacist to tell you, or to get your OK first. A study of every state’s law has the details.

It Will Probably Look Different

US trademark law does not let a generic look exactly like the brand, so the color, shape or markings usually change. The active ingredient, strength and form are the same. An “authorized generic,” made by or for the brand’s own company, can look identical. The FDA explains.

Your Insurance May Change Too

Once a lower-cost version is available, many insurance plans charge more for the brand, or stop covering it. Your plan’s drug list (formulary) says how.

Until a generic is on US pharmacy shelves, be careful with websites that offer “generic Juvisync”. The FDA warns that unlicensed online pharmacies sell counterfeit and unapproved medicines; its BeSafeRx page shows how to check a pharmacy.

Questions people ask about Juvisync

Is there a generic for Juvisync right now?

No. As of October 9, 2026 no generic simvastatin and sitagliptin phosphate is listed for sale in the FDA NDC Directory.

When will Juvisync go generic?

There is no expected month yet. One generic maker has filed an application with FDA. What opens the door, a ruling, a deal or an expiry, is not settled yet.

Will generic simvastatin and sitagliptin phosphate be the same as Juvisync?

Yes in the ways that matter: the same active ingredient, strength and form, with proof that it reaches your blood the same way. Inactive ingredients can differ, which is why some people notice a different look or taste.

How much will the generic cost?

Nobody can say for sure before launch. One company has applied to the FDA to make it. In the FDA’s study of past launches, pharmacies paid about 31% less once one company sold a generic. That is a pattern from past launches, not a prediction for this one.

Has the FDA approved a generic Juvisync?

Not yet. The FDA Orange Book lists no approved generic version of Juvisync.

When does the Juvisync patent expire?

One patent is listed for Juvisync in the FDA Orange Book; it runs to October 2026, counting a six-month pediatric extension. A patent date is not the launch date: settlements and court rulings often bring a generic earlier, and FDA approval or a company’s own plans can make it later. The expected window on this page (a date that is not known yet) weighs all of that.

Has anyone challenged the Juvisync patents?

Yes. The first patent challenge to Juvisync reached the FDA in June 2012, from one company on that first day. The FDA has not approved a first challenger’s generic yet. A patent challenge (a “Paragraph IV certification”) is a generic company telling the FDA that a patent listed for the brand is invalid or will not be infringed by its version. The first companies to file one can earn a 180-day head start, during which the FDA cannot approve the generics that filed after them.
