Imatinib in 2026: What's the Latest?

If you take Imatinib for chronic myeloid leukemia (CML), GIST, or another cancer, you may have heard about supply issues — or experienced them firsthand. Showing up at the pharmacy only to be told your life-saving medication isn't available is a stressful experience no patient should have to face.

In this article, we'll give you the latest update on Imatinib availability in 2026, explain why supply issues happen, discuss current costs, and share practical steps for making sure you don't miss a dose.

Is Imatinib Still in Shortage?

As of early 2026, Imatinib is not listed as critically short on the FDA Drug Shortage database. However, that doesn't mean every pharmacy has it on the shelf. Patients have continued to report intermittent difficulty finding generic Imatinib at chain pharmacies throughout 2025 and into 2026.

The situation is best described as "spotty availability" rather than a full-blown shortage. Some pharmacies have plenty of stock while others are temporarily out. The problem tends to come and go depending on your location, your pharmacy's wholesaler, and which generic manufacturer they order from.

Why Is Imatinib Hard to Find?

Several factors contribute to ongoing availability challenges:

Generic Manufacturer Disruptions

Since Gleevec's patent expired in 2016, Imatinib has been produced by multiple generic manufacturers including Sun Pharma, Teva, Mylan, and Apotex. When one or more manufacturers experience production delays — due to facility issues, raw material problems, or regulatory actions — the available supply tightens.

Supply Chain Complexity

Most Imatinib active pharmaceutical ingredient (API) is manufactured in India, with raw materials sourced from China. Global shipping disruptions, regulatory inspections, and quality control issues at any point in this chain can delay product reaching U.S. pharmacies.

Distribution Allocation Limits

When supply is limited, drug distributors may cap how much each pharmacy can order. This means a pharmacy may want to stock Imatinib but can only get a fraction of what they need from their wholesaler.

Specialty Drug Stocking Patterns

Imatinib is an oncology medication that many general pharmacies don't stock in high quantities. Unlike blood pressure medications or antibiotics, cancer drugs have a smaller patient base at any given location, so pharmacies may not keep large supplies on hand.

How Much Does Imatinib Cost in 2026?

Cost is a major concern for Imatinib patients. Here's what you can expect:

• Brand Gleevec: $12,000 to $16,000 per month for 400 mg daily
• Generic Imatinib (cash price): $150 to $500 per month depending on the pharmacy and manufacturer
• With discount cards: As low as $80 to $120 per month at select pharmacies
• With insurance: Copays vary widely. Specialty tier drugs may have 20-33% coinsurance, meaning you could pay $50 to $200+ per month even with insurance.

Are There New Options for CML Patients?

The good news is that CML treatment continues to advance. In addition to generic Imatinib, patients now have access to several second and third-generation TKIs:

• Dasatinib (Sprycel) — now available as a generic, potentially making it more affordable as an alternative
• Nilotinib (Tasigna) — generic versions available, another second-generation option
• Bosutinib (Bosulif) — approved for newly diagnosed and resistant CML
• Asciminib (Scemblix) — a newer STAMP inhibitor approved for CML, works by a different mechanism than traditional TKIs

These are not direct substitutes — each has different side effects, dosing requirements, and indications. But having more options means your oncologist has flexibility if you can't access Imatinib. Learn more in our guide to Imatinib alternatives.

Final Thoughts

While Imatinib isn't in a critical nationwide shortage in 2026, many patients are still finding it difficult to locate at their local pharmacy. The combination of multiple generic manufacturers, complex supply chains, and pharmacy stocking patterns creates a patchwork of availability that varies from one pharmacy to the next.

The most important thing is to never run out of your medication. Plan ahead, use tools like Medfinder, and stay in close communication with your oncologist and pharmacist. If supply issues persist, your care team can help you explore alternatives or connect you with specialty pharmacies that maintain reliable stock.
