Explains

PharmD, BCPS · Clinical pharmacist Updated

Generic furosemide is expected to be available in April 2034, about 7.5 years away. None is for sale yet.

Why April 2034?

It is when Furoscix’s patents 9,884,039, 10,272,064, 11,433,044 and 12,370,168 end. They cover a way of using it and the product’s formulation, and once they end, generics should be able to go on sale as soon as the FDA approves them. We rate it toss-up: still unsettled. Just as likely to slip as to hold.

If Furoscix’s last patent runs to January 2040, how can a generic come sooner?

The 10 patents that run past the expected month, to January 2040 (11,497,755, 11,559,535, 11,571,434, 11,998,555 and 6 more), cover the product’s formulation and a way of using it. A patent like that protects one way of making or using the medicine, not the medicine itself. A generic company can often make its version a different way or leave that use off its label, or a court can rule the patent invalid or not infringed. That is why the expected month comes before the last protection ends. See the road to a generic

Why hasn’t the FDA approved a generic yet?

That is normal before a launch. The FDA usually can’t give a generic its final approval while a patent or exclusivity still blocks it, so final approval often comes close to the day the generic can be sold. No company holds a “tentative” approval yet either (the FDA’s word for a generic that is ready but still blocked).

Will the generic cost less?

Usually, but no company is recorded as having applied to make one yet, and a single company usually brings only a modest drop. See the price pattern

What should I do now?

Keep taking Furoscix 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.

Furoscix’s Road to a Generic

Furoscix has had the market to itself since the FDA approved it in October 2022 (Scpharmaceuticals Inc A Wholly Owned Sub Of Mannkind Corp). Its 14 listed patents run to January 2040.

The first generic of Furoscix is expected in April 2034.

Why that month: patents 9,884,039, 10,272,064, 11,433,044 and 12,370,168, on a way of using it and the product’s formulation, end then. That is about 6 years before the last listed patent runs out, in January 2040.

Why a Generic Can Come Before January 2040

The last listed patent runs to January 2040, but it covers the product’s formulation and a way of using it, not the medicine itself, which a generic can often work around or challenge. Dr. Brian explains

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. Sources: FDA Orange Book; the expected month from court records and company announcements.

Furoscix Patents and FDA Protections

Every patent and exclusivity the FDA Orange Book lists for Furoscix’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.

The one that matters for a generic launch: patents 9,884,039, 10,272,064, 11,433,044 and 12,370,168, which end in April 2034, the month the first generic is expected. Why the later ones may not hold it back

Who Is Lined Up to Make Generic Furosemide

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

No company is recorded as having applied to the FDA to make a generic Furoscix yet.

2

Approved by the FDA

Not yet. The FDA has not approved a generic furosemide. 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 furosemide 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).

Furoscix 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 Furoscix, 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 Medicare and Medicaid Spend on Furoscix

Big public spending is part of why generic makers line up for a medicine, and why its first generic matters beyond the pharmacy counter. Figures are before manufacturer rebates, which are confidential.

What a Generic Furoscix Means for You

Nothing Changes Until It Is in Pharmacies

Until a generic is actually for sale, keep filling Furoscix 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 Furoscix”. 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 Furoscix

Is there a generic for Furoscix right now?

No. As of October 9, 2026 no generic furosemide is listed for sale in the FDA NDC Directory.

When will Furoscix go generic?

April 2034 is the expected month, and that is toss-up but not certain. It is when Furoscix’s patents 9,884,039, 10,272,064, 11,433,044 and 12,370,168 end. They cover a way of using it and the product’s formulation, and once they end, generics should be able to go on sale as soon as the FDA approves them. The last listed patent runs to January 2040, but it covers the product’s formulation and a way of using it, not the medicine itself, which a generic can often work around or challenge.

Will generic furosemide be the same as Furoscix?

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. No company is recorded as having applied to the FDA to make one yet, and a single company usually brings only a modest drop.

Has the FDA approved a generic Furoscix?

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

When does the Furoscix patent expire?

The FDA Orange Book lists 14 patents for Furoscix; the last runs to January 2040. The one behind the expected month is patents 9,884,039, 10,272,064, 11,433,044 and 12,370,168, which end in April 2034. 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 month on this page (April 2034) weighs all of that.
