How to Keep Prescription Costs Under Control for Chronic Illness
Prescription prices fluctuate quickly. Patients who understand tier changes, generics, biosimilars, and assistance programs can turn unpredictable costs into manageable, strategy-driven decisions.
The National Picture
Prescription expenses remain one of the most unstable parts of chronic-illness care. Cost spikes can appear without warning, and for many households, a single refill can shift the month’s budget. According to the Kaiser Family Foundation (KFF), three in ten U.S. adults report skipping or rationing their prescriptions because of cost. This pattern is closely associated with preventable complications for diabetes, asthma, and autoimmune disease.
The U.S. Department of Health and Human Services Office of the Assistant Secretary for Planning and Evaluation (ASPE) reports that prescription drug spending reached 606 billion dollars in 2023, an eight percent increase from the year before. Rising costs and inconsistent coverage create volatile conditions. These conditions can be managed with precise information and structured decision-making.
When a Tier Change Becomes a Financial Shock
In early 2025, during a period when insurers across several states were updating their drug formularies, Sally encountered her own version of the sudden-spike problem. The situation unfolded at a neighborhood pharmacy where she had filled the same biologic for months. The refill that had reliably cost 125 dollars was suddenly priced at 480 dollars because the medication had moved to a higher tier. That tier shift, which is invisible to most patients until checkout, is a major driver of national spending patterns documented by KFF and ASPE.
Only after speaking with her insurer and pharmacist did she learn that the plan’s mail-order program and a manufacturer copay card applied to her prescription. Within a week, her cost dropped to 60 dollars.
“I remember standing at the pharmacy counter when my biologic went from 125 dollars to 480 dollars overnight because it moved to a higher tier. I almost walked away. Then I learned about my plan’s mail-order option and a manufacturer copay card. Within a week, it dropped back to 60 dollars. I did not change my medication. I changed how I got it.”
— Sally Figueroa
This experience illustrates a national pattern. Costs often change not because the medication changes, but because the billing pathway changes.
Strategies That Work
1. Review the Formulary Each Year
Most commercial and Marketplace plans rebuild their drug lists annually. A medication categorized as preferred one year may move to a non-preferred tier the next. During Open Enrollment, reviewing your insurer’s formulary helps prevent surprise charges and reveals whether generics or alternatives are available.
2. Use Generics and Biosimilars When Appropriate
The U.S. Food and Drug Administration states that generic medications are typically 80 to 85 percent less expensive than brand-name versions and must match them in active ingredients, strength, quality, and performance.
For biologics such as Humira, FDA-approved biosimilars offer substantial savings and undergo rigorous comparison testing. These options reduce annual out-of-pocket costs by thousands when insurers align coverage.
3. Leverage Assistance Programs
Nonprofits and manufacturer programs fill gaps left by inconsistent coverage. Examples include NeedyMeds, Patient Advocate Foundation Copay Relief, GoodRx Health, and SingleCare.
Findings from the Patient Advocate Foundation’s 2023 impact report show that ninety-day mail-order refills lowered monthly out-of-pocket costs by an average of 30 percent for many chronic-care users.
4. Ask Your Provider for “Dispense As Written” Flexibility
When brand-name coverage changes or a tier moves mid-year, providers can authorize an interchangeable generic. This single notation often prevents cost spikes and keeps treatment consistent.
Everyday Conditions, Different Cost Profiles
Asthma and COPD
Generic inhalers now average 50 to 60 dollars, compared with more than 100 dollars for brand-name equivalents.
Rheumatoid Arthritis
Assistance foundations commonly offset more than 1,200 dollars per year in biologic copays for eligible patients.
Diabetes
FDA-approved insulin biosimilars released in 2023 and 2024 cost about twenty percent less than brand-name versions.
When Pharmacists Become Partners
During a mid-2024 period when she was experimenting with timing, refills, and cost-tracking, Sally made a habit of asking her pharmacist a single question at every pickup: “Is there a cheaper way to fill this” This routine opened a conversation about biosimilars available through her infusion center.
That guidance reshaped her annual budget. By switching to an equivalent biosimilar, she saved nearly 900 dollars over the year, which is consistent with FDA and Health Affairs findings on biosimilar adoption.
“Every refill, I ask, ‘Is there a cheaper way to fill this’ One month, my pharmacist told me about a biosimilar that worked just as well for my infusion. It saved me 900 dollars that year. Now I never leave the counter without asking that question.”
— Sally Figueroa
Her story reflects a broader truth. Trusted providers often know the most efficient pathway to the same treatment.
Final Takeaway
Prescription management is a form of financial defense. Reviewing formularies annually, choosing generics and biosimilars when safe, evaluating nonprofit aid, and maintaining open communication with pharmacists can stabilize one of the most unpredictable categories of chronic-care spending.
As FDA and KFF data consistently show, patients who compare their options pay less and achieve more predictable long-term outcomes.
