Here’s the bottom line

Cromolyn sodium concentrate is in shortage, but all four manufacturers reporting the shortage still list available supply in both the 20 mg/1 mL and 100 mg/5 mL strengths. Some supply remains in the distribution chain, though Ailex Pharmaceuticals has stopped making it.

Don’t stop or change your therapy on your own — ask your pharmacist about other manufacturers (see options) and your prescriber about a long-term plan.

These rows are manufacturer reports to the FDA for Cromolyn Sodium Concentrate — they do not necessarily cover every manufacturer that makes this drug. A company appears here only if it told the FDA it has a supply problem, so other makers may still have stock. That’s the basis for the Where else can I get Cromolyn Sodium Concentrate? options further down this page.

Why is Cromolyn Sodium Concentrate in shortage?

For Cromolyn Sodium Concentrate, the shortage situation really comes down to one specific manufacturer — Ailex Pharmaceuticals. They make a couple of versions of the 100 mg/5 mL concentrate, and two of those specific products (distributed by Woodward Pharma Services and Ritedose Pharmaceuticals) are no longer being manufactured. There are still some remaining supplies of those two products moving through the distribution chain, but once that stock runs out, those particular versions won't be replenished. Ailex did not share a more specific public reason for stopping production of those two products beyond a general "other" category.

The good news is that not all versions of this medicine are in short supply. Ailex's third version of the 100 mg/5 mL concentrate (distributed by Omnivium Pharmaceuticals) is still listed as available, and other manufacturers' products — including from Mylan Specialty, Micro Labs, and Rising Pharma — are also currently listed as available.

FDA reason code(s): Other

Based on the manufacturer-reported reason(s) and notes on file with the FDA for Cromolyn Sodium Concentrate, summarized in plain English by HelloPharmacist. A drug can be short for more than one reason, and the FDA updates these as manufacturers report changes.

What should I do if I take Cromolyn Sodium Concentrate?

Cromolyn Sodium Concentrate is on the FDA's current drug-shortage list, but supply remains broadly in place. I want to point out up front that both strengths still have an available source, so the one you take should be findable.

Here is how the strengths break down: both 20 mg/1 mL and 100 mg/5 mL currently have an available source — no strength is completely without supply right now. All four manufacturers on this record are still reporting available product, and none of the listed items is marked unavailable. A few 100 mg/5 mL versions are "no longer manufactured," with some stock still moving through the supply chain, while other sources of that strength remain active. The reported reason is listed only as "Other," and this situation has lasted over a year without eliminating supply.

What you can do:

  • Do not stop, skip, or change your dose on your own.
  • Ask your pharmacy to order your strength — pharmacies can check wholesalers and other manufacturers, since several makers still report supply.
  • If your pharmacy has trouble locating it, ask your prescriber or pharmacist about options, such as using a different strength to make up your dose.
  • Manufacturer contact numbers are listed on this page for reference; your pharmacy usually handles those calls.

This is general, national information and may not match your local pharmacy's actual stock.

See “Where else can I get Cromolyn Sodium Concentrate?” below ↓ The same medicine from manufacturers not reporting a shortage, alternative dosage forms, and therapeutic equivalents with pricing.
If you are a patient:
  • Don’t stop or change the medication on your own — talk to your prescriber first.
  • If this is part of an ongoing or essential regimen (for example HIV treatment or prevention, seizure, heart, transplant, diabetes or mental-health medicines), do not skip or ration doses — contact your pharmacist or prescriber right away to arrange continued supply before you run out.
  • Ask your pharmacy to check other manufacturers, strengths, package sizes, and nearby stores.
  • Ask your prescriber whether a different strength, formulation, or the brand/generic version is appropriate.

Where else can I get Cromolyn Sodium Concentrate?

FDA shortages are manufacturer-reported — a company only shows up on the shortage list if it told the FDA it has a supply problem, so not every maker of Cromolyn Sodium Concentrate is necessarily short. Below we pull together the other still-marketed options that are not reported in shortage: the same medicine from manufacturers that haven’t reported a problem, and alternative dosage forms. These may still be out of stock at your pharmacy, and only your prescriber or pharmacist can decide what’s right for you.

Alternative dosage forms of Cromolyn Sodium

A different form of the same drug (for example a solution when capsules are short). A form change is a clinical decision — ask your prescriber:

Equivalents share the same ingredient, strength, dosage form and route; an AB rating means the FDA considers them substitutable. NADAC is a national retail-pharmacy acquisition benchmark from CMS — not what you pay. Availability is inferred from recent pricing, not a stock check.

How to read the Supply-Risk rating
Low (1–2)Multiple manufacturers still supplying and most strengths or pack sizes sourceable.
Medium (3)Some constraint — fewer suppliers or a notable share of NDCs unavailable.
High (4–5)Down to a single source, most strengths or pack sizes unsourceable, or a long-running outage.
Where does this data come from?
Shortage records come from the FDA Drug Shortages Database API via openFDA (/drug/shortages) — drug, manufacturer & contact, NDC/product, status, availability, reason, therapeutic category and posting/update dates. Current / To Be Discontinued = active; Resolved is kept for history. The Supply-Risk rating is assessed per active ingredient and adds the FDA NDC Directory (still-marketed manufacturers by ingredient & form); same-medicine and equivalent products use First Databank classification + CMS NADAC pricing; Medicaid use + most-affected states come from CMS Medicaid State Drug Utilization Data. Reference only — confirm current status with the manufacturer or FDA before acting on it.
