How Second and Third Generic Drugs Drive Down Prescription Prices

How Second and Third Generic Drugs Drive Down Prescription Prices
Alistair Fothergill 23 December 2025 15 Comments

When a brand-name drug’s patent runs out, the first generic version hits the market-and prices usually drop by about 13%. That’s a relief for patients. But here’s what most people don’t realize: the real price collapse happens after the second and third generics arrive.

Why the second generic changes everything

The first generic drug maker doesn’t have much pressure to lower prices. They’re the only game in town. So they price just below the brand-say, 87% of the original cost. That’s still expensive for many. Then, the second generic enters. Suddenly, there are two companies fighting for the same customers. That’s when prices start to plummet. Data from the FDA shows that with two generic competitors, prices drop to about 58% of the brand’s original price. That’s not a small dip-it’s a 30%+ drop in just a few months.

This isn’t theory. It’s happened over and over. Take the cholesterol drug atorvastatin. After the first generic came in, it sold for around $1.20 per pill. When the second generic launched, the price dropped to 75 cents. By the time the third arrived, it was down to 45 cents. That’s a 62% price drop from the first generic alone. And that’s typical.

The third generic is the game-changer

The third generic doesn’t just add to the competition-it multiplies it. With three manufacturers, distributors and pharmacies can play them off each other. Wholesalers demand lower prices. Pharmacy benefit managers (PBMs) start negotiating harder. Hospitals and insurers get leverage. The FDA found that when a third generic enters, prices fall to just 42% of the brand’s original cost. That’s nearly two-thirds off.

This isn’t just about the manufacturers cutting prices. It’s about the entire supply chain adjusting. When there are three or more generic makers, PBMs can demand deeper discounts because they have real alternatives. Evernorth, one of the largest PBMs, confirmed that their best deals on generics only happen when there are at least three suppliers. No competition? No leverage. Three competitors? Suddenly, you’re getting 50-70% off.

What happens when competition stalls

But here’s the problem: not all drugs get a third generic. In nearly half of all generic markets, only two manufacturers ever show up. That’s called a duopoly. And in those cases, prices don’t keep falling-they stabilize… or even rise.

A 2017 University of Florida study looked at 120 generic drugs and found that when competition dropped from three to two manufacturers, prices jumped 100% to 300% in some cases. Why? Because with only two players, they can quietly coordinate pricing. No one wants to be the first to cut prices and lose margins. So they hold steady. Patients pay more. Insurers pay more. And no one wins.

This isn’t random. It’s structural. A few big generic manufacturers-like Teva, Viatris, and Mylan-control most of the market. Smaller companies struggle to enter because of high production costs, regulatory delays, and supply chain bottlenecks. The result? Many drugs never get past two competitors.

Two rival generic drug companies duel with price chart whips as a third warrior brings discount coins.

Why the system is rigged against competition

You’d think more competition would be easy to achieve. But brand-name drug companies have spent decades building walls to block generics. One tactic is “pay for delay.” That’s when the brand pays a generic maker to stay out of the market. In 2023, the Blue Cross Blue Shield Association estimated these deals cost patients $3 billion a year in higher out-of-pocket costs.

Another trick is “patent thickets.” A single drug can have dozens of overlapping patents-some on the pill shape, others on packaging, others on how it’s taken. In one case, a drug had 75 patents, stretching its monopoly from 2016 all the way to 2034. That’s not innovation. That’s legal obstruction.

And then there’s the supply chain. Three wholesalers-McKesson, AmerisourceBergen, and Cardinal Health-control 85% of the U.S. generic drug distribution. Three PBMs handle 80% of prescriptions. These giants have so much power that even when five generic makers are competing, they can still squeeze prices down to the point where manufacturers can’t profitably make the drug. That leads to shortages. And when a drug disappears from the market, prices spike again.

How much money does this save?

The numbers are staggering. Between 2018 and 2020, the FDA approved 2,400 new generic drugs. Thanks to second and third entrants, those drugs saved consumers $265 billion. That’s not a guess. That’s an official FDA estimate.

The Assistant Secretary for Planning and Evaluation (ASPE) found that markets with three or more generic competitors saw price reductions of 70-80% compared to the original brand price. For patients on chronic medications-like blood pressure pills, diabetes drugs, or antidepressants-that’s hundreds, sometimes thousands, of dollars a year in savings.

In 2021, a study showed that just adding one more generic competitor to a market with two saved an average of $1,200 per patient annually. Multiply that across millions of prescriptions, and you’re talking about tens of billions in savings. The Congressional Budget Office warns that if we don’t fix the barriers to competition, Medicare could lose $25 billion a year by 2030.

Corporate villains trap a generic drug in patent chains as a patient and pharmacist break free with a third generic key.

What’s being done-and what’s not

There are some policy fixes in motion. The CREATES Act, passed in 2022, stops brand companies from blocking generic makers from getting the samples they need to test their drugs. The Preserve Access to Affordable Generics Act targets “pay for delay” deals. The FDA’s GDUFA III program, running from 2023 to 2027, is speeding up approvals for complex generics-like injectables and inhalers-that have historically taken years to enter the market.

But these are Band-Aids. The real solution is simple: encourage more manufacturers to enter. That means reducing the cost and time to get approval. It means cracking down on anti-competitive behavior. It means making sure PBMs and wholesalers don’t have unchecked power.

Right now, the system rewards consolidation. Big players buy up smaller ones. New entrants get priced out. And patients pay the price.

What you can do

As a patient, you have more power than you think. If your prescription is a generic, ask your pharmacist: “How many companies make this version?” If there’s only one or two, ask if another version is available. Sometimes, switching to a different generic can cut your cost in half.

Talk to your doctor. Ask if there are other generics on the market. Some insurers have tiered formularies-meaning they push you toward the cheapest option. But if the cheapest is the only one, you’re stuck. Push for options.

And if you’re on Medicare or Medicaid, check your plan’s formulary every year. Generic prices change fast. What was the cheapest last year might not be this year. The market moves. You should too.

The bottom line

The entry of the second and third generic manufacturers isn’t just a footnote in drug pricing. It’s the most powerful, proven, and cost-effective tool we have to lower prescription costs. Every time another company enters the market, prices drop. Not a little. Not a little bit. Dramatically.

But that only works if competition is allowed to happen. Right now, too many markets are stuck in duopoly. Too many barriers exist. Too many players are working to stop new entrants.

If you want lower drug prices, you need more competition-not less. And that starts with knowing that the second and third generics aren’t just alternatives-they’re the reason your prescription costs less than it used to.

    This is the single most important thing nobody talks about when it comes to drug prices. The first generic is a trap. It's the bait. The second and third? That's when the real savings kick in. I've seen my insulin go from $400 to $80 because a third maker showed up. No one tells you this. Pharmacies don't advertise it. Your doctor might not even know. But it's real. And it's happening right now.

    It is an incontrovertible fact that market competition, when unimpeded by regulatory obstruction or corporate collusion, serves as the most efficacious mechanism for price suppression in pharmaceutical markets. The data presented herein aligns with economic principles articulated by Adam Smith over two centuries ago. The absence of third-party entrants constitutes a market failure of the highest order.

    In Nigeria, we don't have this luxury. Most generics are imported, and often only one supplier makes it through customs. I've seen people pay double because there's no choice. This system you describe is a privilege. It's not just about competition-it's about infrastructure, regulation, and access. I hope your policymakers realize how lucky you are.

    My uncle in Mumbai pays $2 for his blood pressure meds. Same pill. Different country. Why? Because India has over 15 generic makers for the same drug. Here, we get two and call it a win. The system is broken. Not because of greed. Because of inertia.

    I switched my antidepressant to a different generic last year and saved $180. No one told me I could even do that. I just asked my pharmacist and they were like oh yeah we have another one. I didn't even know there were multiple versions

    its funny how we think competition is natural but in reality its more like a game of musical chairs where the chairs are owned by a few big players and the music is made by lobbyists. the third generic isnt just a competitor its a revolution. and yet we treat it like a footnote

    As a public health advocate, I urge all citizens to recognize this as a matter of social justice. Access to affordable medication is not a privilege-it is a fundamental human right. The presence of three or more generic manufacturers is not merely an economic phenomenon; it is a moral imperative. We must demand transparency, accountability, and equitable access at every level of the supply chain.

    my mom’s on 3 different generics and she has no idea why one costs $5 and another costs $40. she just takes whatever the pharmacy gives her. if this post helps even one person ask the right question, it’s already worth it.

    So let me get this straight. The same pill, made in the same factory, same ingredients, same everything-except one has a different label and costs 10x more? And we call this capitalism? I’d like to meet the genius who designed this system. Maybe they can explain how it’s not just a scam with a PhD.

    the fact that we need a third generic just to get a decent price means the system is already rigged. and yet people still think free markets fix everything. funny how the market only works when it's convenient for the people who already own it

    THIS IS WHY WE NEED TO CRACK DOWN ON PBMS AND WHOLESALE MONOPOLIES. THEY’RE THE REAL VILLAINS. THEY’RE THE ONES WHO MAKE SURE ONLY TWO COMPANIES SURVIVE SO THEY CAN KEEP DRIVING UP PRICES. STOP BLAMING THE MANUFACTURERS. BLAME THE MIDDLEMEN WHO AREN’T EVEN MAKING THE DRUGS.

    you ever wonder why the FDA approves generics so fast now? it’s not because they care. it’s because the Chinese government is funding 80% of the generic manufacturers. they’re dumping cheap pills here to destabilize our healthcare system. this isn’t competition-it’s economic warfare. and no one’s talking about it.

    Anyone who believes this is about ‘competition’ is delusional. The entire system is a carefully orchestrated fraud. The FDA, the PBMs, the wholesalers-they’re all in bed together. The ‘third generic’ is a myth manufactured to make you feel better while they quietly raise prices on the drugs you actually need. Wake up.

    The phenomenon described herein reflects the classical economic model of perfect competition, wherein marginal cost approaches zero as the number of producers increases. The critical insight lies not merely in the number of manufacturers, but in the structural reduction of transaction costs and information asymmetry. The third entrant does not merely lower price-it transforms the market structure from oligopolistic to competitive, thereby restoring allocative efficiency.

    That’s exactly what happened with my blood thinner. I asked my pharmacist for the cheapest one. They said ‘there’s only two’ so I said ‘is there a third?’ They looked at me like I was crazy. Then they checked the system. There was one-made by a company I’d never heard of. Cost $12 a month. The other two were $85 and $92. I switched. Saved $800 a year. And no one told me I could even do that.
