Azathioprine in 2026: Where Things Stand

If you take Azathioprine and you've been hearing about drug shortages, you probably want a straight answer: is it still hard to find? Can I get my prescription filled?

Here's the current picture for Azathioprine (sold as Imuran and Azasan) in 2026 — what's actually in shortage, what's available, and what you can do about it.

Is Azathioprine Still in Shortage?

It depends on which form you need:

• Injectable Azathioprine (IV): Yes, the injectable form (azathioprine sodium 100 mg vials) remains on the FDA drug shortage list. Hikma, a primary manufacturer, has had vials on back order with no estimated release date since late 2024. This primarily affects hospitals and infusion centers.
• Oral Azathioprine tablets: The oral tablets are not on the FDA's formal drug shortage list. However, patients report intermittent difficulty finding specific strengths or manufacturers at their local pharmacy. This is more of a spotty availability problem than a true nationwide shortage.

The distinction matters. If you take Azathioprine tablets by mouth — which the vast majority of patients do — your medication is being manufactured and distributed. The challenge is that not every pharmacy has it on the shelf at every moment.

Why Is It Hard to Find?

Several overlapping factors contribute to the difficulty:

• Limited manufacturers: Only a handful of companies produce generic Azathioprine tablets. Any disruption at even one facility tightens supply across the board.
• Wholesaler distribution patterns: Large chain pharmacies may be allocated limited quantities during tight supply periods, leaving individual locations short.
• Cross-indication demand: Azathioprine is prescribed across rheumatology, gastroenterology, transplant medicine, dermatology, and neurology. This broad demand means supply must stretch across many specialties.
• Injectable shortage spillover: When hospitals can't get IV Azathioprine, some shift to crushing oral tablets for patients who can't swallow, further straining oral supply.

How Much Does Azathioprine Cost in 2026?

The cost picture for Azathioprine is relatively favorable since it's available as a generic:

• With a GoodRx or SingleCare coupon: As low as $13-$17 for 30 tablets of 50 mg
• Cash price without insurance or coupon: Approximately $40-$70 for 30 tablets of 50 mg
• Higher doses or brand names: 100 tablets of Azathioprine 100 mg can run $300-$464 at full retail price
• With insurance: Typically Tier 1 or Tier 2 on most formularies, meaning copays of $5-$25 in many plans

Are There New Options in 2026?

While no new formulations of Azathioprine have launched recently, there are developments worth knowing about:

• Generic competition remains strong: Multiple generic manufacturers continue to produce Azathioprine 50 mg tablets, which helps keep prices low and supply generally available.
• Alternative immunosuppressants: If you're unable to find Azathioprine, your doctor may consider alternatives like Mycophenolate Mofetil, Methotrexate, or Mercaptopurine depending on your condition.
• TPMT/NUDT15 testing is more routine: Genetic testing before starting Azathioprine is increasingly standard, which helps doctors optimize dosing and reduce side effects — potentially reducing the need for medication switches that strain supply of alternative drugs.

How to Find Azathioprine in Stock

If your pharmacy can't fill your prescription, try these steps:

1. Search on Medfinder: Check real-time pharmacy availability near you — it's the fastest way to locate Azathioprine in stock.
2. Call independent pharmacies: They often have different supply channels than chain pharmacies.
3. Ask about different strengths: If 50 mg is unavailable, 75 mg or 100 mg Azasan tablets may be in stock.
4. Try mail-order pharmacy: Mail-order services may have access to broader distribution networks.
5. Contact your prescriber early: Don't wait until you're out. Reach out with at least 7-10 days of supply remaining.

Final Thoughts

The Azathioprine situation in 2026 is manageable but requires patience and planning. The injectable form remains in shortage, but oral tablets are generally available — you may just need to look a little harder or try a different pharmacy.

Stay proactive with your refills, use tools like Medfinder to check stock, and communicate early with your doctor if you're having trouble. Missing doses of an immunosuppressant can have serious consequences, so don't wait until the last minute to act.
