Explains

PharmD, BCPS · Clinical pharmacist Updated

It already is. A generic fosaprepitant dimeglumine is listed for sale by 13 companies, so ask your pharmacy whether it can fill your prescription with one.

Why January 2039?

It is when Focinvez’s patents 11,065,265 and 12,042,504 end. They cover the product’s formulation, and once they end, generics can 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.

What should I do now?

Ask your pharmacy whether it can fill your prescription with a generic. It may look different from Focinvez, but the active ingredient, strength and form are the same. What a generic means for you

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

Focinvez’s Road to a Generic

Focinvez has had the market to itself since the FDA approved it in August 2023 (Steriscience Pte Ltd). Its 2 listed patents run to January 2039.

The first generic of Focinvez is expected in January 2039.

Why that month: patents 11,065,265 and 12,042,504, on the product’s formulation, end then.

Brand alone on the market Since FDA approval, August 2023
Patent 11,065,265 Expires January 2039 The patent behind the expected month of generic availability
Patent 12,042,504 Expires January 2039 The patent behind the expected month of generic availability
Brand alone on the market Patent on the formulation First generic expected Swipe the chart sideways to see every year.

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.

Focinvez Patents and FDA Protections

Every patent and exclusivity the FDA Orange Book lists for Focinvez’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 11,065,265 and 12,042,504, which end in January 2039, the month the first generic is expected.

Who Is Lined Up to Make Generic Fosaprepitant Dimeglumine

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 Focinvez, but the FDA has already approved 9 companies (step 2), and every approval starts with an application.

2

Approved by the FDA

The FDA has approved generic versions from 9 companies, the first in June 2016. 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 fosaprepitant dimeglumine is listed for sale by 13 companies. Ask your pharmacy whether it can fill your prescription with it.

Focinvez 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 Focinvez, 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 Focinvez

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 Focinvez 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 Focinvez

Is there a generic for Focinvez right now?

Yes. The FDA NDC Directory lists a generic fosaprepitant dimeglumine from 13 companies. Ask your pharmacy whether it can fill your prescription with it.

When will Focinvez go generic?

It already has. The FDA NDC Directory lists a generic fosaprepitant dimeglumine from 13 companies, so ask your pharmacy whether it can fill your prescription with one.

Will generic fosaprepitant dimeglumine be the same as Focinvez?

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 9 companies to make a generic, and how many of them launch decides how far the price falls.

Has the FDA approved a generic Focinvez?

Yes. The FDA Orange Book lists approved generic versions from 9 companies, the first approved in June 2016: Fresenius Kabi USA LLC, Be Pharmaceuticals AG, Msn Laboratories Private Ltd, Mylan Laboratories Ltd and 5 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 Focinvez patent expire?

The FDA Orange Book lists 2 patents for Focinvez; the last runs to January 2039. The one behind the expected month is patents 11,065,265 and 12,042,504, which end in January 2039. 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 (January 2039) weighs all of that.
