Explains

PharmD, BCPS · Clinical pharmacist Updated

Generic afatinib dimaleate is expected to be available between 2027 and 2028. None is for sale yet.

Why 2027 to 2028?

The brand company and a generic maker settled their patent fight and agreed on when a generic can launch. We rate it likely: firm enough to plan around, but a court ruling or a new deal could still move it.

If Gilotrif’s last patent runs to January 2031, how can a generic come sooner?

The 3 patents that run past the expected month, to January 2031 (8,426,586, 8,545,884 and 10,004,743), cover the active ingredient and the product’s formulation. A generic can still come sooner if a court rules a patent invalid or not infringed, or if the companies settle on an earlier date. Here, a settlement between the companies sets the date. Generic companies have been challenging Gilotrif’s patents with the FDA since July 2017. That is why the expected month comes before the last protection ends. See the road to a generic

If the FDA approved a generic, why can’t I buy one?

FDA approval is permission to sell, not a launch. 2 companies have held approvals since July 2026, but a patent, a settlement or a company’s own plans can hold a generic back until the expected month. See who is lined up

Will the generic cost less?

Usually, and more so as more companies sell one. 9 companies have applied to the FDA to make it. In the FDA’s study of past launches, pharmacies paid over 95% less once six or more companies sold a generic. See the price pattern

What should I do now?

Keep taking Gilotrif 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.

Gilotrif’s Road to a Generic

Gilotrif has had the market to itself since the FDA approved it in July 2013 (Boehringer Ingelheim). Its 5 listed patents run to January 2031 (1 already expired). Generic companies have challenged its patents with the FDA since July 2017.

The first generic of Gilotrif is expected between 2027 and 2028.

Why that month: the brand company and a generic maker settled their patent fight and agreed on when a generic can launch.

Why a Generic Can Come Before January 2031

The last listed patent runs to January 2031; a court ruling or a settlement can bring a generic sooner. 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.

Gilotrif Patents and FDA Protections

Every patent and exclusivity the FDA Orange Book lists for Gilotrif’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 Gilotrif

The first patent challenge to Gilotrif reached the FDA in July 2017, from 7 companies on that first day. The FDA approved a first challenger’s generic in July 2026, and the list records no sale by a first challenger yet.

What Is a Patent Challenge?

A generic company that wants to sell its version before Gilotrif’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 Afatinib Dimaleate

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

9 companies have applied to the FDA to make generic afatinib dimaleate.

The FDA keeps the other applications private until it acts on them, so those companies are not named here.

First in line. 7 of them were first in line, all filing on the first day any company did: they can share 180 days on the market before the other generics, which is why being first matters.

Generic companies have challenged Gilotrif’s patents with the FDA since July 2017: see the patent challenges.

2

Approved by the FDA

The FDA has approved generic versions from 2 companies, the first in July 2026. 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

Not yet. No company lists a generic afatinib dimaleate for sale with the FDA.

Gilotrif 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 Gilotrif, 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 Gilotrif

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 Gilotrif Means for You

Nothing Changes Until It Is in Pharmacies

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

Is there a generic for Gilotrif right now?

No. As of October 9, 2026 no generic afatinib dimaleate is listed for sale in the FDA NDC Directory. 2 generic versions are FDA-approved (Orange Book), which usually means it is waiting on patents or on the maker’s own launch plans.

When will Gilotrif go generic?

2027 to 2028 is the expected window, and that is likely but not certain. The brand company and a generic maker settled their patent fight and agreed on when a generic can launch. The last listed patent runs to January 2031; a court ruling or a settlement can bring a generic sooner.

Will generic afatinib dimaleate be the same as Gilotrif?

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. 9 companies have applied to the FDA to make it. In the FDA’s study of past launches, pharmacies paid over 95% less once six or more companies sold a generic. That is a pattern from past launches, not a prediction for this one.

Has the FDA approved a generic Gilotrif?

Yes. The FDA Orange Book lists approved generic versions from 2 companies, the first approved in July 2026: Apotex Inc and Hetero Labs Ltd Unit V. 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 Gilotrif patent expire?

The FDA Orange Book lists 5 patents for Gilotrif; the last runs to January 2031, 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 (2027 to 2028) weighs all of that.

Has anyone challenged the Gilotrif patents?

Yes. The first patent challenge to Gilotrif reached the FDA in July 2017, from 7 companies on that first day. The FDA approved a first challenger’s generic in July 2026, and the list records no sale by a first challenger 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.
