Leflunomide can be hard to find at pharmacies in 2026. Learn why this RA medication faces supply issues and what you can do to get your prescription filled.
You depend on Leflunomide to manage your rheumatoid arthritis. So when your pharmacist tells you they can't fill your prescription — or that it'll be days or even weeks before they can get it in — it's more than an inconvenience. It's a disruption to your health.
In 2026, many patients across the United States have reported difficulty finding Leflunomide at their usual pharmacy. Whether you take the 10 mg or 20 mg tablet, the experience is frustratingly similar: backorders, transfers, and unanswered questions.
In this article, we'll explain what Leflunomide is, why it's been harder to find, and — most importantly — what you can do about it right now.
Leflunomide (brand name Arava) is a disease-modifying antirheumatic drug, or DMARD. It's prescribed to treat active rheumatoid arthritis (RA) by slowing the disease process and reducing joint damage over time.
Unlike pain relievers that only mask symptoms, Leflunomide works at the root of the problem. It inhibits an enzyme called dihydroorotate dehydrogenase (DHODH), which is essential for the rapid multiplication of immune cells that attack your joints. By blocking pyrimidine synthesis in these overactive lymphocytes, Leflunomide helps calm the autoimmune response that drives RA.
It's typically prescribed as a 20 mg daily tablet (sometimes reduced to 10 mg for tolerability). Some doctors start with a loading dose of 100 mg daily for three days, though this practice has become less common due to side effect concerns.
Leflunomide has been FDA-approved since 1998, and the brand-name version Arava is manufactured by Sanofi. Today, most patients take generic Leflunomide made by companies like Teva, Apotex, Sandoz, and Aurobindo.
There's no single reason Leflunomide has been difficult to find. Instead, it's a combination of supply chain factors that have created intermittent shortages. Here are the main reasons:
Although Leflunomide has been off-patent for years, only a handful of companies produce the generic version. When even one manufacturer experiences a production delay — whether due to equipment issues, FDA inspection findings, or raw material problems — it can ripple across the entire supply chain. With fewer producers to pick up the slack, pharmacies feel the impact quickly.
The active pharmaceutical ingredients (APIs) used to make Leflunomide are often sourced from overseas suppliers. Global supply chain disruptions — including shipping delays, regulatory changes in exporting countries, and quality control issues at API facilities — can slow down or temporarily halt production of the finished tablets.
Rheumatoid arthritis affects an estimated 1.3 million Americans, and Leflunomide remains a key treatment option — particularly for patients who can't tolerate Methotrexate or need an alternative DMARD. As prescribing patterns shift and new patients start therapy, demand can outpace the available supply, especially for the 20 mg strength.
Even when Leflunomide is being manufactured, it doesn't always make it to every pharmacy shelf. Wholesale distributors allocate inventory based on historical ordering patterns, which means smaller or independent pharmacies may receive less stock during tight supply periods. If your pharmacy hasn't ordered Leflunomide regularly, they may be lower on the priority list.
The good news: Leflunomide isn't completely unavailable. In most cases, it's a matter of finding the right pharmacy at the right time. Here are practical steps you can take:
Medfinder lets you search for Leflunomide availability at pharmacies near you. Instead of calling pharmacy after pharmacy, you can see which locations currently have it in stock — saving you time and stress. Learn more about finding Leflunomide in stock near you.
Big chain pharmacies aren't your only option. Independent pharmacies often have more flexibility in their ordering and may be able to source Leflunomide from different distributors. Specialty pharmacies that focus on autoimmune conditions can also be a valuable resource.
If Leflunomide remains unavailable for an extended period, your rheumatologist may recommend a temporary or permanent switch to another DMARD. Options like Methotrexate, Sulfasalazine, or Hydroxychloroquine may be appropriate depending on your situation. Read about alternatives to Leflunomide.
Many pharmacies can place a direct order with their wholesaler for Leflunomide, even if they don't normally keep it on the shelf. This may take a few days, but it's often a reliable way to get your medication.
It can be tempting to stretch your remaining supply or skip doses to make it last. But Leflunomide works best when taken consistently, and interruptions can lead to disease flares. If you're running low, contact your doctor's office right away — they may have samples or be able to help you find a supply.
Finding Leflunomide in 2026 may require a bit more effort than it used to, but it's far from impossible. The key is to be proactive: use tools like Medfinder to check availability, explore multiple pharmacy options, and stay in close communication with your healthcare team.
Your treatment for rheumatoid arthritis is too important to leave to chance. With the right approach, you can keep your Leflunomide therapy on track — even when supply gets tight.
