Allopurinol Shortage Update: What Patients Need to Know in 2026

If you take allopurinol for gout, kidney stones, or to prevent tumor lysis syndrome, you may have heard concerns about medication shortages. Here's what patients need to know about allopurinol availability in 2026 — based on current FDA data and pharmacy supply chain information.

Is Allopurinol Currently in Shortage? (2026 Update)

As of early 2026, allopurinol oral tablets (100 mg and 300 mg) are not listed on the FDA's official Drug Shortage database. The oral formulation is considered widely available with multiple manufacturers producing generic versions. This is good news for the millions of Americans who take allopurinol daily for gout management.

However, the IV formulation (Aloprim) has historically had supply disruptions and is primarily used in hospital settings for tumor lysis syndrome. If you're on oral allopurinol for gout, this does not affect you.

Has Allopurinol Ever Been in Shortage Before?

The IV form of allopurinol (Aloprim, 500 mg injection) has appeared on FDA shortage lists in the past, driven by manufacturing challenges and limited commercial demand. Oral allopurinol tablets have generally maintained robust supply because they're produced by numerous generic manufacturers. Generic drug markets are generally more resilient to shortages than single-source drugs.

Why Might Individual Patients Still Have Trouble Finding It?

Even when no national shortage exists, patients sometimes run into trouble. Here's why:

• Individual pharmacy stock-outs: A specific pharmacy may temporarily run out due to ordering delays or unexpected demand.
• The 200 mg strength: The 200 mg tablet is far less commonly stocked than 100 mg and 300 mg tablets. Many pharmacies simply don't carry it regularly.
• Rural pharmacy access: Patients in rural areas may have fewer pharmacy options, making any single stock-out more impactful.
• Generic manufacturer transitions: When a major manufacturer exits the generic market or changes distribution, pharmacies may temporarily experience a gap while switching to a different manufacturer's product.

How to Monitor Allopurinol Availability Going Forward

Patients who want to stay ahead of potential supply issues can:

1. Refill prescriptions a week or two before running out, rather than waiting until the last tablet.
2. Ask your doctor about switching to a 90-day supply via mail-order pharmacy — this reduces exposure to pharmacy-level stock-outs.
3. Check the FDA Drug Shortage Database at accessdata.fda.gov for current shortage information.
4. If you're having trouble, use medfinder to have pharmacies near you checked for availability — it's faster than calling each one yourself.

What Should I Do If I Can't Find Allopurinol Right Now?

If you're currently unable to fill your prescription, here are immediate steps:

• Try multiple pharmacies — chain pharmacies like Walmart and Costco often have more consistent supply of generics
• Ask your pharmacist if a different tablet strength can be dispensed with your doctor's approval
• Contact your prescriber to discuss a short-term bridge or alternative medication
• Do not stop allopurinol abruptly if you've been on it long-term — this can trigger a gout flare as uric acid levels shift

Why Gout Patients Must Be Extra Careful About Lapses

Allopurinol is not like a pain reliever you take as needed — it's a chronic maintenance medication. When you first start it or when you restart it after a gap, uric acid levels shift as the drug mobilizes urate crystals from joint tissue. This mobilization can actually trigger gout flares during the early weeks of therapy, which is why doctors often prescribe colchicine or low-dose NSAIDs as prophylaxis for the first 3–6 months.

If you've experienced a gap in allopurinol therapy and restart, talk to your doctor about whether to restart at a lower dose and titrate up again to minimize the risk of a flare.

Summary

Allopurinol oral tablets are not in national shortage in 2026. Localized stock-outs can and do happen, but solutions are usually available within your area. Plan ahead, use mail-order when possible, and read our guide on why allopurinol can be hard to find for more context on availability issues.
