Is Aller-Cort in shortage in 2026? Get the latest update on Triamcinolone nasal spray availability, pricing, and what patients can do right now.
If you've been struggling to find Aller-Cort at your local Costco, you might be wondering if there's a nationwide shortage. You're not imagining things — the shelves really are emptier than usual during allergy season. But the situation is more nuanced than a simple "yes" or "no."
In this update, we'll break down the current availability of Aller-Cort and its equivalent products, explain what's driving stock-outs, and give you a clear action plan for getting your allergy relief in 2026.
As of March 2026, there is no official shortage of Triamcinolone Acetonide nasal spray listed by the FDA or the American Society of Health-System Pharmacists (ASHP). The active ingredient in Aller-Cort is being manufactured and distributed at normal levels.
However, that doesn't mean it's easy to find at every store. What many patients are experiencing is localized stock-outs — meaning specific stores, particularly Costco locations, run out temporarily due to high demand. This is different from a true drug shortage, where the medication is unavailable across the entire supply chain.
It's worth noting that Aller-Cort is a Costco-exclusive Kirkland Signature product. Its distribution is inherently more limited than medications available at every pharmacy chain. When your Costco location sells out, it can feel like a shortage even though Nasacort and generic Triamcinolone are available elsewhere.
Several factors combine to make Aller-Cort difficult to find at certain times:
Allergy seasons are getting longer and more intense. Warmer winters and earlier springs mean pollen seasons start sooner and last longer. When pollen counts spike, so does demand for nasal steroid sprays — and supply can't always keep up in real time.
Unlike Flonase or Nasacort, which are sold at tens of thousands of retail locations, Aller-Cort is only available at the roughly 600 Costco warehouses in the U.S. and online at Costco.com. This concentrated distribution means each location serves a larger customer base, making stock-outs more likely.
Costco shoppers tend to buy in bulk. During allergy season, it's common for people to grab multiple bottles at once — either for their household or to stock up. This accelerates the rate at which individual stores sell through their inventory.
Even when the manufacturer is producing at full capacity, there are natural delays in getting products from the factory to the warehouse shelf. These delays are especially noticeable when demand spikes unexpectedly early in the season.

One of the biggest reasons people seek out Aller-Cort specifically is the price. Here's how costs compare across your options:
Even if you can't find Aller-Cort's specific low price point, generic alternatives and discount cards can get you close. For a complete guide to saving money, see our article on how to save money on Aller-Cort.
The allergy treatment landscape continues to evolve. Here's what's new:
With Nasonex (Mometasone) now available over the counter alongside Flonase, Rhinocort, and Nasacort, patients have more choices than ever before. Competition among brands is driving prices down and improving availability.
Major retailers like Walmart (Equate), Target (Up & Up), CVS, and Walgreens all offer their own generic versions of intranasal corticosteroids. These are often the cheapest option and are widely stocked.
Tools like Medfinder make it easier than ever to check which pharmacies have your medication in stock before you leave the house. This is especially valuable during peak allergy season when availability changes daily.
Here's your action plan:

While Aller-Cort may be temporarily hard to find at your local Costco during peak allergy season, there is no true shortage of Triamcinolone Acetonide nasal spray in 2026. The active ingredient is widely available under multiple brand names and generics at pharmacies across the country.
The key is flexibility. If Aller-Cort isn't on the shelf, Nasacort, generic Triamcinolone, or another OTC nasal steroid spray can provide the same relief. Use Medfinder to check availability, and don't let temporary stock-outs keep you from managing your allergies effectively.
