Gastrocrom is hard to find in 2026 due to limited manufacturers, low demand, and supply chain issues. Learn why and what you can do to get it.
You've got a prescription for Gastrocrom in hand, but pharmacy after pharmacy tells you the same thing: "We don't have it in stock." If this sounds familiar, you're far from alone. Gastrocrom (Cromolyn Sodium oral concentrate) has become one of the hardest medications to find in the United States — and the problem has only gotten worse heading into 2026.
In this post, we'll break down exactly what Gastrocrom is, why it's so difficult to find, and most importantly, what you can do about it right now.
Gastrocrom is the brand name for Cromolyn Sodium oral concentrate, a medication classified as a mast cell stabilizer. It works by preventing mast cells in your body from releasing histamine and other chemicals that cause allergic and inflammatory symptoms.
The FDA approved Gastrocrom for the management of symptoms associated with systemic mastocytosis — a condition where the body produces too many mast cells. These symptoms include diarrhea, flushing, headaches, vomiting, abdominal pain, nausea, itching, and urticaria (hives).
Doctors also prescribe Gastrocrom off-label for conditions like food allergies, irritable bowel syndrome (IBS), eosinophilic gastroenteritis, and other mast cell-related disorders. For many patients, it's the only medication that effectively manages their symptoms.

There are several reasons why Gastrocrom has become increasingly difficult to locate at pharmacies across the country. Here are the main factors:
Gastrocrom is currently manufactured by Azurity Pharmaceuticals (which took over production from Allergan). Unlike blockbuster drugs that have dozens of generic competitors, Cromolyn Sodium oral concentrate has extremely limited manufacturing. When only one or two companies make a drug, any production hiccup — equipment maintenance, raw material shortages, quality control issues — can ripple across the entire supply chain.
Systemic mastocytosis is a rare condition. Because the patient population is small, Gastrocrom doesn't generate the kind of revenue that incentivizes multiple pharmaceutical companies to produce it. Manufacturers may prioritize higher-volume, more profitable drugs, leaving niche medications like Gastrocrom vulnerable to shortages.
Even when Gastrocrom is being manufactured, it may not reach every pharmacy. Large retail chains like CVS and Walgreens often stock medications based on demand at each location. If a particular store rarely fills Gastrocrom prescriptions, they simply won't keep it on their shelves. This means you might need to call multiple pharmacies — or look beyond the big chains — to find it.
Gastrocrom has experienced recurring availability issues since the mid-2010s. These intermittent shortages have made pharmacies hesitant to stock it, creating a frustrating cycle: pharmacies don't stock it because demand seems low, and patients can't find it because pharmacies don't stock it.

The good news is that Gastrocrom isn't impossible to find — it just takes some extra effort. Here are practical steps you can take:
Tools like Medfinder let you search for Gastrocrom availability at pharmacies near you in real time. Instead of calling pharmacy after pharmacy, you can check stock online and save yourself hours of frustration.
Independent pharmacies and compounding pharmacies are often more flexible than big chains. They may be willing to special-order Gastrocrom for you or even compound a Cromolyn Sodium oral solution if the brand-name product isn't available. Ask your pharmacist about ordering directly from the wholesaler.
If you absolutely cannot find Gastrocrom, talk to your prescriber about alternative medications. Depending on your condition, options like Ketotifen, Hydroxyzine, or Famotidine might help manage your symptoms while you wait for Gastrocrom to become available.
Pharmacy stock changes frequently. If a pharmacy is out today, they may have it next week. Try calling early in the week (Monday or Tuesday mornings) when new shipments often arrive. For more tips, read our guide on how to find Gastrocrom in stock near you.
If cost is also a barrier, there may be programs that can help. Visit our post on how to save money on Gastrocrom for details on coupons, discount cards, and patient assistance options.
Finding Gastrocrom in 2026 is genuinely challenging — but it's not hopeless. The key is knowing why it's hard to find so you can take the right steps. Whether that means using Medfinder to check pharmacy stock, trying a specialty pharmacy, or exploring alternatives with your doctor, there are real options available to you.
You shouldn't have to fight this hard for a medication you need. But until the supply situation improves, a little persistence and the right tools can make all the difference.
