VESIcare LS’s Road to a Generic

VESIcare LS has had the market to itself since the FDA approved it in May 2020 (Astellas Pharma US Inc). Its one listed patent runs to May 2031. Generic companies have challenged its patents with the FDA since May 2021.

The patents are not the problem. A generic still needs FDA sign-off, and that is when it is expected.

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.

VESIcare LS Patents and FDA Protections

Every patent and exclusivity the FDA Orange Book lists for VESIcare LS’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 VESIcare LS

The first patent challenge to VESIcare LS reached the FDA in May 2021, from one company on that first day. 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 VESIcare LS’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 Solifenacin Succinate

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 application count is on record for VESIcare LS, but the FDA has already approved 18 companies (step 2), and every approval starts with an application.

Generic companies have challenged VESIcare LS’s patents with the FDA since May 2021: see the patent challenges.

2

Approved by the FDA

The FDA has approved generic versions from 18 companies, the first in April 2014. Approved is not the same as on sale: patents, a settlement or the company’s own plans can still hold a launch.

3

For Sale in Pharmacies

Yes. A generic solifenacin succinate is listed for sale by 29 companies. Ask your pharmacy whether it can fill your prescription with it.

VESIcare LS 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 VESIcare LS, 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 VESIcare LS

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 VESIcare LS Means for You

Nothing Changes Until It Is in Pharmacies

A generic is listed for sale now, so your pharmacy may already be able to fill your prescription with it.

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.

Questions people ask about VESIcare LS

Is there a generic for VESIcare LS right now?

Yes. The FDA NDC Directory lists a generic solifenacin succinate from 29 companies. Ask your pharmacy whether it can fill your prescription with it.

When will VESIcare LS go generic?

It already has. The FDA NDC Directory lists a generic solifenacin succinate from 29 companies, so ask your pharmacy whether it can fill your prescription with one.

Will generic solifenacin succinate be the same as VESIcare LS?

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. The FDA has already approved 18 companies to make a generic, and how many of them launch decides how far the price falls.

Has the FDA approved a generic VESIcare LS?

Yes. The FDA Orange Book lists approved generic versions from 18 companies, the first approved in April 2014: Teva Pharmaceuticals USA, Alembic Pharmaceuticals Ltd, Alkem Laboratories Ltd, Bostal LLC and 14 more. Approved is not the same as on sale: patents, a settlement or the company’s own plans can still hold a launch.

When does the VESIcare LS patent expire?

One patent is listed for VESIcare LS in the FDA Orange Book; it runs to May 2031. 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 VESIcare LS patents?

Yes. The first patent challenge to VESIcare LS reached the FDA in May 2021, 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.
