📣 The Overlooked Downsides of the Inflation Reduction Act for Medicare Part D Users
Most people know the Inflation Reduction Act will add a $2,100 annual cap on Medicare drug costs starting in 2026.
That is true — and it will help those with very high prescription expenses.
But what many don’t realize is that the law has also created some unexpected challenges for millions of people enrolled in stand-alone Part D drug plans (PDPs).
Here’s what we’re seeing right now:
🔹 Smaller Formularies (Fewer Medications Covered)
• Plans are covering fewer brand-name drugs.
• More medications have been moved to higher tiers or removed entirely.
• Prior authorizations, step therapy, and other restrictions have increased.
🔹 Higher Cost-Sharing on Many Prescriptions
To prepare for the 2026 cap, plans have shifted more cost to the beginning of the year:
• Many brand-name drugs now cost more per fill than they did last year.
• Medications that were $35–$47 may now be $50–$100+ depending on the plan.
• Specialty and certain maintenance drugs have noticeably higher copays.
🔹 Why This Is Happening
The new cap limits how much any member can spend out of pocket, but it also changes how plans manage pricing and risk.
As a result:
• People who typically spent far less than $2,100 per year may now be paying more, not less.
• Many are being pushed closer to the cap simply because each prescription costs more — not because they’re taking more medications.
🔹 Who’s Affected Most
👉 Especially those on stand-alone Part D (PDP) plans — which cover only prescription drugs.
These plans have less flexibility than Medicare Advantage plans, which can offset increased drug costs with other benefits.

Bottom Line
The Inflation Reduction Act offers important protections, but it has also led to:
• Higher per-prescription costs
• Narrower formularies
• Increased cost-sharing for brand-name and specialty drugs
For many seniors — especially those on PDP plans — prescription costs are rising now, even though the cap is still two years away.
