Why Is My Prescription So Expensive — and What Can I Do About It?

Why is my specific prescription so expensive?

Several factors drive high out-of-pocket costs:

• Brand-name drug with no generic available: When a drug is still under patent protection, only the original manufacturer can sell it. Without competition, list prices can be very high.
• You have not yet met your deductible: With insurance but before hitting your deductible, you may pay the full negotiated price — which is still often much higher than what you would pay using a discount card.
• The drug is in a high formulary tier: Insurance plans classify drugs into tiers; higher tiers (specialty or brand-name drugs) carry higher copays or coinsurance 2Ref 2Federal Trade Commission (2024).Pharmacy Benefit Managers: The Powerful Middlemen Inflating Drug Costs and Squeezing Main Street Pharmacies.The three largest PBMs process nearly 80% of US prescriptions; their pricing arrangements — including spread pricing and rebate structures — can increase out-of-pocket costs for patients rather than reducing them.
• No insurance: People without coverage pay cash prices, which can be far higher than insured prices.
• Specialty drugs: Biologics and certain oncology or autoimmune treatments can cost thousands per month at list price and represent a distinct affordability challenge that requires specific assistance programs.

Behind many of these factors is a system of pharmacy benefit managers (PBMs) — the intermediaries between manufacturers, insurers, and pharmacies. The three largest PBMs process nearly 80% of all US prescriptions and negotiate rebates and reimbursement rates that are not publicly disclosed. Investigations by the Federal Trade Commission have found that PBMs' pricing arrangements — including opaque rebate structures and spread pricing — can lead to higher costs for patients rather than lower ones 2Ref 2Federal Trade Commission (2024).Pharmacy Benefit Managers: The Powerful Middlemen Inflating Drug Costs and Squeezing Main Street Pharmacies.The three largest PBMs process nearly 80% of US prescriptions; their pricing arrangements — including spread pricing and rebate structures — can increase out-of-pocket costs for patients rather than reducing them3Ref 3Freed M, Cubanski J, Williams E, Pestaina K (KFF) (2026).What to Know About Pharmacy Benefit Managers (PBMs) and Federal Efforts at Regulation.PBMs may favor higher-priced drugs with higher rebates over lower-priced alternatives; lack of transparency in PBM-manufacturer contracts limits plan sponsors' insight into actual acquisition costs.

What are the most effective steps to lower the cost?

Ask about a generic or biosimilar: If a generic or biosimilar version of your medication exists, it contains the same active ingredient at the same dose and is regulated to the same safety and efficacy standard. The savings can be dramatic 4Ref 4Berman J, Dugdale DC (reviewers); A.D.A.M. Editorial Team (2024).How to Save Money on Medicines.Patient-facing guidance from NLM on using generics, mail-order pharmacies (90-day supply), discount programs, and patient assistance programs to reduce out-of-pocket prescription costs.

Use a discount card: GoodRx, RxSaver, and similar programs are free and negotiate lower prices at the pharmacy counter independently of insurance. For many common generics, the discount-card price is lower than your insurance copay. Compare both before paying 4Ref 4Berman J, Dugdale DC (reviewers); A.D.A.M. Editorial Team (2024).How to Save Money on Medicines.Patient-facing guidance from NLM on using generics, mail-order pharmacies (90-day supply), discount programs, and patient assistance programs to reduce out-of-pocket prescription costs.

Ask your prescriber for a therapeutic alternative: There may be a drug in the same class with a generic available that would work for your condition. Be direct: 'This medication is too expensive — is there an equivalent that costs less?'

Look into manufacturer patient assistance programs: Most major drug makers offer programs for people who cannot afford their medications, particularly for brand-name drugs. The NeedyMeds database (needymeds.org) lists nearly 4,700 medications with at least one patient assistance program offering them at low or no cost. Your prescriber's office can often help with the application.

Request a 90-day supply: Many plans offer a lower per-unit cost for a 90-day supply, especially through a mail-order pharmacy affiliated with your insurer 4Ref 4Berman J, Dugdale DC (reviewers); A.D.A.M. Editorial Team (2024).How to Save Money on Medicines.Patient-facing guidance from NLM on using generics, mail-order pharmacies (90-day supply), discount programs, and patient assistance programs to reduce out-of-pocket prescription costs.

Appeal your insurance tier placement: If a drug is placed on a high tier or excluded, you have the right to request a formulary exception. Your prescriber documents medical necessity; your insurer's member services line can explain the process.

Check state programs and Medicare Extra Help: If you are on Medicare Part D with limited income, the Extra Help (Low Income Subsidy) program can significantly reduce costs — covering premiums, deductibles, and copayments 5Ref 5Centers for Medicare & Medicaid Services (2024).Low Income Subsidy for Medicare Prescription Drug Coverage (Extra Help).Medicare Extra Help (Low Income Subsidy) program reduces prescription drug costs for eligible beneficiaries — covering premiums, deductibles, and copayments for Part D enrollees with limited income. Some states offer additional pharmaceutical assistance for lower-income residents.

What can my pharmacist do that I might not expect?

Pharmacists are one of the most underused resources in the drug-cost conversation. They can tell you which discount card gives the lowest price for that drug at that pharmacy, check whether a generic or biosimilar is available, and point you to manufacturer copay cards if you are commercially insured. Simply ask: 'Is there a cheaper way for me to get this?'

What if I am already skipping doses because of cost?

Please tell your prescriber. Cost-related medication nonadherence is more common than many clinicians realize — about 12.6% of adults with established cardiovascular disease report missing doses or taking less medication to save money 6Ref 6Khera R, Valero-Elizondo J, Das SR, et al. (2019).Cost-Related Medication Nonadherence in Adults With Atherosclerotic Cardiovascular Disease in the United States, 2013 to 2017.12.6% of adults with atherosclerotic cardiovascular disease — approximately 2.2 million people — reported cost-related medication nonadherence including missing doses or taking less medication to save money. The medical consequences of skipping doses — especially for conditions such as diabetes, heart failure, high blood pressure, or epilepsy — can be serious and lead to preventable hospitalizations. The goal is to find a medication regimen that works for you at a price you can sustain 1Ref 1KFF (Kaiser Family Foundation) (2023).KFF Health Tracking Poll July 2023: The Public's Views Of New Prescription Weight Loss Drugs And Prescription Drug Costs.About 3 in 10 adults (28%) report difficulty affording prescription drugs; 31% say they have not taken medicine as prescribed due to cost, including 12% who cut pills or skipped doses. There is no stigma in asking for help.
