The cost to get a generic drug approved by the FDA isn’t just a number on a balance sheet-it’s a barrier that shapes what medicines patients can afford, and when they can get them. For every generic pill that hits the shelf, there’s a multi-year, multi-million-dollar journey through paperwork, reformulations, and regulatory reviews. And while the system was designed to keep drugs safe, its hidden costs are slowing down access to affordable medicine.
What You’re Really Paying for When You Buy a Generic
When you pick up a generic version of a brand-name drug, you’re saving money-often 80% or more. But that savings doesn’t come for free. The real cost is buried in the approval process. Under the Generic Drug User Fee Amendments (GDUFA), generic manufacturers pay the FDA to review their applications. In fiscal year 2025, that means a base application fee of $136,485, plus a facility fee of $238,055 per manufacturing site. For most companies, that’s $375,000 just to submit one drug for review.
Compare that to brand-name drugs, where a single New Drug Application (NDA) can cost over $3.6 million. It seems unfair, right? But here’s the catch: the FDA doesn’t require brand-name companies to prove their drug works from scratch. They only need to show it’s safe and effective. Generic makers? They have to prove their version is identical-down to the particle size, coating, and dissolution rate. That’s where things get expensive.
The 2015 Policy That Changed Everything
In 2015, the FDA quietly changed how it reviews complex generics-drugs like inhalers, nasal sprays, and topical creams that don’t have a simple chemical formula. Before that, the agency gave manufacturers detailed feedback on why a formulation failed. If the active ingredient didn’t dissolve properly, they’d say: ‘The particle size is too large.’ If the spray didn’t deliver the right dose, they’d say: ‘The nozzle pressure is off.’
After 2015, that feedback vanished. Instead, companies got vague letters saying: ‘The product is not substantially equivalent.’ No specifics. No direction. Just a dead end.
One mid-sized generic company told RAPS in 2024 they spent $8.7 million over three years trying to get a nasal spray approved. They tried three different formulations-each one costing millions-because the FDA wouldn’t tell them what exactly was wrong. That’s not innovation. That’s guesswork at taxpayer and patient expense.
Why Some Generics Take 5 Years to Arrive
It takes 18 to 24 months just to develop a generic drug before you even send it to the FDA. Then comes the review. The official target is 10 months. The reality? In 2023, the average review time was 11.2 months. For complex generics, it’s often 18 to 24 months-sometimes longer.
Why? Because 58% of complex generic applications get rejected on the first try. And each rejection means a new round of reformulation, retesting, and resubmission. Each one costs $2 to $5 million and adds 8 to 12 months to the timeline.
Take testosterone replacement therapy. Between 2016 and 2020, generic versions were delayed by 4.7 years. During that time, patients paid 300% more for the brand-name version. That’s not a coincidence. It’s a consequence of the system.
Who’s Paying the Price?
Patients are. In 2024, Americans filled 4.3 billion prescriptions. 90% of them were generics. But 83% of brand-name drugs still have no generic competition five years after their patents expire. Why? Because the FDA’s approval process is too slow, too opaque, and too expensive for many companies to navigate.
On Reddit, patients share stories of paying $1,200 a month for a drug that could be $50 as a generic. One person wrote about being forced to choose between glipizide for diabetes and their rent. Another described skipping apixaban doses because the generic hadn’t been approved yet. These aren’t rare cases. They’re systemic failures.
Meanwhile, pharmacists defend the current system. One in New York told Pharmacy Times: ‘The extra scrutiny prevents quality issues like the 2022 valsartan recall that affected 22 million patients.’ That’s true. But is the cost of safety worth the cost of delay? When patients can’t afford their meds, safety becomes a luxury.
The Fight for Change: H.R. 1843
In September 2025, two lawmakers-Rep. Neal Dunn (R-FL) and Rep. Kevin Mullin (D-CA)-introduced H.R. 1843, the ‘Increasing Transparency in Generic Drug Applications Act.’ It’s simple: require the FDA to give specific, actionable feedback on failed generic applications.
The Congressional Budget Office estimates this one change could cut approval times for complex generics by 18 to 24 months. That means 12 to 15 more complex generics reach the market each year. And according to their analysis, that would save $1.8 to $2.3 billion annually in healthcare costs.
By November 2025, the bill had 72 co-sponsors. It’s scheduled for committee markup in December. This isn’t just policy. It’s a lifeline for patients.
What’s Next for Generic Drug Approval?
The FDA is already preparing for GDUFA IV-the next round of user fees, starting in 2028. Industry groups want fee increases of 3% to 5% per year to hire more reviewers. The FDA says they need $725 to $750 million annually just to meet current goals.
But here’s the problem: more money doesn’t fix broken processes. If the FDA keeps rejecting applications without telling companies why, even double the staff won’t help. The real solution isn’t more money. It’s more clarity.
Meanwhile, the FDA announced in September 2025 it will accelerate review pathways for 15 high-priority complex generics by 2027. That’s a start. But 15 is a drop in the bucket. There are hundreds of delayed generics waiting.
Why This Matters Beyond the Bottom Line
Generics saved $467 billion in 2024. That’s not a statistic. That’s 4.3 billion prescriptions filled at a fraction of the cost. That’s Medicare enrollees saving $1,152 each. That’s a diabetic choosing food over insulin no longer being the norm.
But if we keep letting bureaucratic delays and vague feedback stall the pipeline, those savings will shrink. The FDA’s job isn’t to be a gatekeeper. It’s to be a bridge-between innovation and access, between safety and affordability.
Right now, the system favors the status quo. Brand-name companies get years of market exclusivity. Generic makers get a mountain of paperwork and silence. Patients get the bill.
The fix isn’t complicated. Give clear feedback. Speed up reviews for complex drugs. Let competition work. The savings are there. The technology is there. The will? That’s what’s still up for debate.
How much does it cost to get a generic drug approved by the FDA?
The total cost to submit one generic drug application (ANDA) in 2025 is roughly $375,000. This includes a $136,485 product fee, a $238,055 facility fee, and additional costs for testing, documentation, and reformulation. For complex generics, total development and approval costs can exceed $10 million due to multiple failed submissions.
Why are generic drug approvals taking longer than before?
Since 2015, the FDA stopped giving specific feedback on formulation issues for complex generics like inhalers and nasal sprays. Without knowing exactly what failed, manufacturers must guess and retry-often multiple times. This trial-and-error process adds 2 to 3 years to development timelines. Average review times have increased from 8 months under GDUFA I to over 11 months today.
Do generic drugs cost less because they’re cheaper to make?
No. Generic drugs are chemically identical to brand-name versions, so manufacturing costs are often similar. The savings come from not having to repeat expensive clinical trials. But regulatory costs have ballooned. The real price difference is in marketing and patent protection-brand-name companies spend billions on promotion and legal battles to delay generics. Generics just pay the FDA’s fees and wait.
What’s the difference between a standard and a complex generic drug?
Standard generics are simple pills with a single active ingredient and straightforward delivery-like metformin or lisinopril. Complex generics include inhalers, injectables, topical creams, and nasal sprays that require precise physical and chemical properties to work. These are harder to copy because small changes in particle size, viscosity, or spray pattern can affect how the drug behaves in the body. The FDA treats them as entirely new products, even though they’re generics.
How does H.R. 1843 help generic drug manufacturers?
H.R. 1843 would require the FDA to provide detailed, written feedback on why a generic drug application was rejected. Instead of vague letters, companies would get specific technical guidance-like ‘increase particle size by 15 microns’ or ‘adjust nozzle pressure to 28 psi.’ This would cut down on trial-and-error, reduce approval times by 18-24 months for complex generics, and lower development costs by an estimated 25-40%.
Why haven’t more generic versions of expensive drugs hit the market?
Even after a brand-name drug’s patent expires, 83% still have no generic competitor after five years. That’s not because no one wants to make one-it’s because the approval process is too slow, too expensive, and too unpredictable. For complex drugs, the cost of failure can be $10 million or more. Many small manufacturers simply can’t afford to play the game. Big companies wait until patents expire and then buy up the rights, delaying competition even further.
