Nitazoxanide Shortage Update: What Patients Need to Know in 2026

If you've been prescribed nitazoxanide (Alinia) and can't find it at your pharmacy, you're not imagining things — this is a real and frustrating problem that many patients encounter. But the situation is more nuanced than a traditional drug shortage. Here's the current picture for 2026.

Is There an Official Nitazoxanide Shortage in 2026?

As of 2026, generic nitazoxanide 500 mg tablets are NOT listed on the FDA's official drug shortage database. This means the FDA has not determined that demand is outpacing supply nationwide for the generic tablets.

However, brand Alinia has had documented distribution challenges. Brand Alinia formulations — tablets and the oral suspension — have been listed as discontinued by certain distributors. This does NOT mean nitazoxanide is unavailable, but it does mean patients who specifically need the brand may face hurdles.

The Real Issue: Inconsistent Pharmacy Stocking

The main problem patients encounter with nitazoxanide is not a nationwide supply crisis — it's that many retail pharmacies simply don't stock it because demand is low. This is a critical distinction:

• National shortage: Drug can't be obtained anywhere because manufacturing or supply is disrupted.
• Stocking gap: Drug is manufactured and available from wholesalers, but individual pharmacies don't keep it on their shelves because they rarely dispense it.

Nitazoxanide falls into the second category. As a specialty antiparasitic with a relatively small patient population, most pharmacies have little incentive to maintain standing stock. The result: many patients hear "we don't carry that" when it's actually available and could be ordered within 24-48 hours.

What Happened to Brand Alinia?

Alinia was originally manufactured by Romark Laboratories and was FDA-approved starting in 2002 (oral suspension) and 2004 (tablets). When the patent expired and generic competition entered in 2020, the brand market share declined. Some distributors have since discontinued brand Alinia formulations or reduced availability.

The brand oral suspension (Alinia for Oral Suspension, 100 mg/5 mL) is the most affected. There is currently no FDA-approved generic for this formulation. Children ages 1-11 who need the liquid form face the greatest challenge, as this is effectively a single-source product with limited availability.

Generic Nitazoxanide Tablets: Better News

FDA-approved generic nitazoxanide 500 mg tablets are manufactured by Rising Pharmaceuticals and distributed by Lupin Pharmaceuticals under license. These generics are therapeutically equivalent to brand Alinia tablets and are more reliably available through wholesalers. The problem remains: many pharmacies don't stock them because they seldom receive prescriptions for them.

If your prescription says "Alinia," ask your doctor or pharmacist to switch to the generic: "nitazoxanide 500 mg tablets, substitution permitted." This immediately expands your pharmacy options.

What Should I Do If I Can't Find It?

Your best steps right now: ask for the generic by name, target hospital outpatient pharmacies and independent pharmacies, and use medfinder to have pharmacies in your area called on your behalf. See our full guide on how to find nitazoxanide in stock near you for a step-by-step breakdown.

What's the Outlook for Nitazoxanide Availability?

For generic nitazoxanide tablets, availability is expected to remain stable. The drug is manufactured with multiple suppliers. The greater uncertainty is around the oral suspension for children, where no generic alternative exists and brand distribution is inconsistent.

Patients and providers can monitor the FDA drug shortage database at fda.gov/drugs for any official updates. If demand for nitazoxanide rises — for example, due to increased prescribing or a regional outbreak of waterborne illness — stocking at pharmacies may improve organically as well.

Key Takeaways for 2026

• Generic nitazoxanide tablets are NOT in an FDA-declared shortage in 2026
• Brand Alinia has had distribution challenges; some formulations discontinued
• The real problem is low stocking at pharmacies due to low demand — not a supply crisis
• Oral suspension for children is the hardest form to find (no generic available)
• Ask for generic by name and use medfinder or targeted pharmacy calls to locate stock
