Explains

PharmD, BCPS · Clinical pharmacist Updated

Generic cobicistat, elvitegravir, emtricitabine, and tenofovir disoproxil fumarate is expected to be available between 2029 and 2030. None is for sale yet.

Why 2029 to 2030?

The brand company and a generic maker settled their patent fight and agreed on when a generic can launch. We rate it probable: more likely than not, but it can still move.

If Stribild’s last patent runs to April 2033, how can a generic come sooner?

The patent that runs to April 2033 (10,039,718) covers the product’s formulation. 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, a settlement between the companies sets the date. Generic companies have been challenging Stribild’s patents with the FDA since October 2018. 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, and more so as more companies sell one. One company has applied to the FDA to make it. In the FDA’s study of past launches, pharmacies paid about 31% less once one company sold a generic, which would take the $150.14 pharmacies pay per tablet for Stribild today to about $103.60. See the price estimate

What should I do now?

Keep taking Stribild 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.

Stribild’s Road to a Generic

Stribild has had the market to itself since the FDA approved it in August 2012 (Gilead Sciences Inc). Its 7 listed patents run to April 2033. Generic companies have challenged its patents with the FDA since October 2018.

The first generic of Stribild is expected between 2029 and 2030.

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 April 2033

The last listed patent runs to April 2033, but it covers the product’s formulation, 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.

Stribild Patents and FDA Protections

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

The first patent challenge to Stribild reached the FDA in October 2018, from one company on that first day.

What Is a Patent Challenge?

A generic company that wants to sell its version before Stribild’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 Cobicistat, Elvitegravir, Emtricitabine, and Tenofovir Disoproxil Fumarate

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

One company has applied to the FDA to make generic cobicistat, elvitegravir, emtricitabine, and tenofovir disoproxil fumarate.

The FDA names a company only once it approves its application, even tentatively, and it has not done that for this one yet, so the company is not named here. Names often come out in the brand company’s patent lawsuits or in the companies’ own announcements.

First in line. One of them was first in line: the first company to challenge the brand’s patents can earn 180 days on the market before the other generics, which is why being first matters.

Generic companies have challenged Stribild’s patents with the FDA since October 2018: see the patent challenges.

2

Approved by the FDA

Not yet. The FDA has not approved a generic cobicistat, elvitegravir, emtricitabine, and tenofovir disoproxil fumarate. 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 cobicistat, elvitegravir, emtricitabine, and tenofovir disoproxil fumarate 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).

What a Generic Could Cost

What Pharmacies Pay for Stribild Today$150.14per tablet · October 2026
Our Estimate for Generic Stribildabout $103.60per tablet once generics reach pharmacies, about 31% less than today

How we estimate it. We start from what pharmacies pay for Stribild today: $150.14 per tablet for Stribild tablet in October 2026, from the national NADAC survey. Then we apply the FDA’s finding of how far that price 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). Stribild has one company lined up, so our estimate uses the figure for one company. More companies would bring the price lower; fewer, less of a drop.

Dollar figures apply FDA’s median drops to the $150.14 pharmacies pay per tablet today. An estimate from the pattern, not a price quote: what you pay depends on your insurance or discount card.

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 Stribild Means for You

Nothing Changes Until It Is in Pharmacies

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

Is there a generic for Stribild right now?

No. As of October 9, 2026 no generic cobicistat, elvitegravir, emtricitabine, and tenofovir disoproxil fumarate is listed for sale in the FDA NDC Directory.

When will Stribild go generic?

2029 to 2030 is the expected window, and that is probable 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 April 2033, but it covers the product’s formulation, not the medicine itself, which a generic can often work around or challenge.

Will generic cobicistat, elvitegravir, emtricitabine, and tenofovir disoproxil fumarate be the same as Stribild?

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. One company has applied to the FDA to make it. In the FDA’s study of past launches, pharmacies paid about 31% less once one company sold a generic, which would take the $150.14 pharmacies pay per tablet for Stribild today to about $103.60. That is a pattern from past launches, not a prediction for this one.

Has the FDA approved a generic Stribild?

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

When does the Stribild patent expire?

The FDA Orange Book lists 7 patents for Stribild; the last runs to April 2033, 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 (2029 to 2030) weighs all of that.

Has anyone challenged the Stribild patents?

Yes. The first patent challenge to Stribild reached the FDA in October 2018, from one company on that first day. 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.

How much does Stribild cost now?

Pharmacies paid about $150.14 per tablet for Stribild tablet in October 2026, by the national survey of what pharmacies pay (NADAC). That is the pharmacy’s cost, not your price: what you pay depends on your insurance or discount card.
