Having trouble finding Bimzelx? Learn why this biologic for psoriasis and other conditions can be hard to get and what you can do about it in 2026.
You finally found a treatment that works — or your doctor prescribed one that could change everything — and now you can't actually get it. If you've been searching for Bimzelx (Bimekizumab-bkzx) and hitting dead ends, you're not imagining things. This medication can be genuinely difficult to find and fill.
Bimzelx is one of the most effective biologics available for conditions like moderate to severe plaque psoriasis, psoriatic arthritis, ankylosing spondylitis, and hidradenitis suppurativa. But getting it into your hands involves more hoops than most medications. In this post, we'll break down exactly why Bimzelx is so hard to find in 2026 and what you can do about it.
Bimzelx is a prescription biologic medication made by UCB, Inc. Its generic name is Bimekizumab-bkzx. It belongs to a class of drugs called interleukin-17 (IL-17) inhibitors — specifically, it's the first and only biologic that blocks both IL-17A and IL-17F, two proteins that drive inflammation in autoimmune conditions.
The FDA first approved Bimzelx in October 2023 for plaque psoriasis, and it has since gained approval for psoriatic arthritis, ankylosing spondylitis, non-radiographic axial spondyloarthritis, and hidradenitis suppurativa. It's administered as a subcutaneous injection using a prefilled syringe or autoinjector.

There are several reasons why getting Bimzelx can feel like an uphill battle. Here are the main ones:
Unlike pills you pick up at your local CVS or Walgreens, Bimzelx is a specialty biologic. That means it's only available through specialty pharmacies — not your neighborhood drugstore. Specialty pharmacies handle medications that need special storage (Bimzelx must be refrigerated), come at high cost, and require clinical monitoring.
This means you can't just walk into any pharmacy and ask for it. Your prescription has to be routed to a specific specialty pharmacy, which adds time and complexity.
Almost every insurance plan requires prior authorization before covering Bimzelx. This means your doctor has to submit paperwork proving you need this specific drug. The process can take days or even weeks.
On top of that, many insurers enforce step therapy — they require you to try (and fail) other, often cheaper, biologics before they'll approve Bimzelx. You might need to show that drugs like Humira, Cosentyx, or Taltz didn't work for you before your insurance will cover Bimzelx.
The cash price of Bimzelx runs between $16,000 and $22,000 per month without insurance. Even with insurance, copays for specialty biologics can be steep. This price tag means pharmacies don't stock it widely, and the financial paperwork can delay your first dose.

Bimzelx was only approved in the U.S. in late 2023, with additional indications added through 2024. As a newer biologic, not all providers are familiar with prescribing it, and not all specialty pharmacies have established supply chains for it. Awareness and availability are still catching up to demand.
The good news is that there are concrete steps you can take:
Medfinder helps you check which specialty pharmacies have Bimzelx available and can connect you with options near you. Instead of calling around blindly, you can see real-time stock information.
Ask your prescriber's office to handle the prior authorization process proactively. Many dermatology and rheumatology offices have staff dedicated to navigating insurance approvals for biologics. The sooner they submit, the sooner you get your medication.
UCB, the manufacturer of Bimzelx, offers the MyNavigate support program. If you're commercially insured, you may pay as little as $5 per dose. The program also provides a dedicated Nurse Navigator who can help you work through insurance issues and find a specialty pharmacy.
If you're uninsured or underinsured, UCB offers a Patient Assistance Program that may provide Bimzelx at no cost. Your doctor's office can help you apply, or you can find information through resources like NeedyMeds and RxAssist.
If the wait becomes too long, talk to your doctor about whether a temporary alternative like Cosentyx (Secukinumab), Taltz (Ixekizumab), or Humira (Adalimumab) makes sense while you work on getting Bimzelx approved.
Bimzelx is a groundbreaking biologic, but the reality of specialty pharmacy distribution, insurance hurdles, and high costs means getting it isn't always straightforward. The key is to be proactive: use tools like Medfinder, lean on your doctor's office for support, and explore every savings option available.
