  2. Has the FDA approved a generic? Not yet None in the FDA’s records yet Why not yet?
  3. When does the brand’s protection end? May 2044 The last of 10 listed patents Why sooner?
  4. Can you buy a generic today? Not yet No company lists one for sale

Explains

PharmD, BCPS · Clinical pharmacist

Generic milsaperidone is expected to be available between 2036 and 2037. None is for sale yet.

Why 2036 to 2037?

The patent fight is likely to end in an agreement that sets the launch. The terms are not public yet. We rate it probable: more likely than not, but it can still move.

If Bysanti’s protection runs to May 2044, how can a generic come sooner?

The patent that runs to May 2044 (12,478,619) covers 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. Here, the companies are expected to settle on a date. 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 Bysanti 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.

Bysanti’s Road to a Generic

Bysanti has had the market to itself since the FDA approved it in February 2026 (Vanda Pharmaceuticals Inc). Its FDA protection (new chemical entity) runs to February 2031. Its 10 listed patents run to May 2044.

The first generic of Bysanti is expected between 2036 and 2037.

Why that month: the patent fight is likely to end in an agreement that sets the launch. The terms are not public yet.

Why a Generic Can Come Before May 2044

The last listed patent runs to May 2044, but it covers 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.

Bysanti Patents and FDA Protections

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

Who Is Lined Up to Make Generic Milsaperidone

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 Bysanti yet.

2

Approved by the FDA

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

Bysanti 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 Bysanti, 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 Bysanti Means for You

Nothing Changes Until It Is in Pharmacies

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

Is there a generic for Bysanti right now?

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

When will Bysanti go generic?

2036 to 2037 is the expected window, and that is probable but not certain. The patent fight is likely to end in an agreement that sets the launch. The terms are not public yet. The last listed patent runs to May 2044, but it covers a way of using it, not the medicine itself, which a generic can often work around or challenge.

Will generic milsaperidone be the same as Bysanti?

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 Bysanti?

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

When does the Bysanti patent expire?

The FDA Orange Book lists 10 patents for Bysanti; the last runs to May 2044. 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 (2036 to 2037) weighs all of that.
