As prescription prices continue to rise, individuals and their families often have to cope with the financial and emotional stress of trying to afford essential medications.
In fact, a 2021 study found that the average prescription costs in the United States are 256 times greater than those in 32 other countries.
Most expensive drugs

Below, we look at some of the most expensive medications.
Zolgensma
Priced at over $2 million for a single dose, Zolgensma is prescribed to treat spinal muscular atrophy. It is a groundbreaking form of gene therapy that offers potential long-term benefits. For some people, this can justify its high cost by offsetting lifelong treatments.
Luxturna
Costing around $850,000 for both eyes, Luxturna provides a new treatment for a rare inherited retinal disease, called biallelic RPE65 mutation-associated retinal dystrophy. It is the first gene therapy for a genetic disease that’s been approved by the Food and Drug Administration (FDA).
Ravicti
Ravicti is priced at approximately $790,000 annually. It helps manage urea cycle disorders by removing ammonia from the bloodstream.
Actimmune
Actimmune costs $572,000 annually. Doctors prescribe it for chronic granulomatous disease (a genetic disorder affecting white blood cells) and severe, malignant osteopetrosis (a group of bone disorders). This medication belongs to a class of drugs called interferons.
Soliris
With a price tag of $500,000 per year, Soliris treats some rare conditions by reducing the destruction of red blood cells.
Takhzyro
Takhzyro, with an annual cost of around $450,000, treats hereditary angioedema by preventing episodes of swelling.
Brineura
Brineura treats a specific form of Batten disease, a rare neurological disorder. It costs about $730,000 annually.
Myalept
Myalept is priced at $300,000 annually. It addresses complications of a deficiency in leptin (a hormone related to hunger) in people with generalized lipodystrophy.
Gattex
Gattex costs around $295,000 per year. It is used to help manage short bowel syndrome.
Blincyto
Blincyto is used to treat a form of leukemia. It is priced at $173,000 for a standard 28-day course of treatment.
Factors affecting prescription drug costs
Understanding prescription drug pricing is important, especially when you are trying to make the best decisions for your health while also managing expenses.
Several factors can influence the price you pay for prescription medications:
- Research and development: Pharmaceutical companies invest significant resources into the research and development of new drugs. This process can take years and involves multiple stages of testing to make sure a medication is safe and works properly. This is often the reason given for the high cost of newly developed drugs.
- Patent protection: When a new drug is patented, it blocks other companies from creating generics, allowing the original company to set the price. A new patent typically lasts for 20 years. Once the patent ends, prices usually come down.
- Manufacturing costs: The complexity of producing some medications — especially biologics, which are drugs made from living organisms — can be high. These costs get passed to the people prescribed the medication.
- Insurance coverage: Whether you have health insurance and what sort you have plays a significant role in determining your out-of-pocket costs. Depending on your plan, you might have copays, deductibles, or coinsurance that affect the final amount you pay. Your plan might not cover some drugs at all, or they might be on a higher pricing tier, leading to higher costs.
- Regulatory environment: The Biden-Harris Administration is taking steps to reduce prescription drug costs by allowing Medicare to negotiate prices directly. Starting with 10 major medications, the plan aims to expand to 60 drugs over 4 years, with over 20 added each year. These measures challenge large pharmaceutical companies’ (sometimes called Big Pharma) pricing and aim to ease the financial burdens for people who need these medications.
- Demand and competition: If a drug is designed to treat a rare condition, it might be priced higher because demand will naturally be low. Conversely, if there are multiple treatment options for a condition or generic versions of the medication available, competition might drive prices down.
