Riluzole Oral Suspension (Teglutik, Tiglutik) shortage
Riluzole oral suspensions (Teglutik, Tiglutik) are on the FDA’s drug shortage list as of Oct 6, 2026. The company reporting it blames manufacturing-quality requirements.
Tiglutik / Teglutik (riluzole) oral suspension has been in shortage for over a year due to manufacturing compliance issues. The 5 mg/1 mL strength still has supply from the one reporting manufacturer, but the 50 mg/10 mL strength currently has no listed source.
Don’t stop or change your therapy on your own — ask your pharmacist about other companies’ versions (see options) and your prescriber about a long-term plan.

Yes, still current as of Oct 6, 2026. 1 of the 2 strengths is still made by at least one company; 1 is not. The one company that reported this shortage says it still has some supply, and we could not find another company that sells it. Your pharmacy may still need to order it.
The charts count only the companies that reported this shortage to the FDA; companies that haven’t reported a problem are in the green card, and the Supply-Risk rating counts them too.

These rows are company reports to the FDA for Riluzole Oral Suspension — they do not cover every company that lists this medicine. A company appears here only if it told the FDA it has a supply problem, so other companies may still have stock. That’s the basis for the Where else can I get riluzole? options further down this page.
Why is riluzole in shortage?
Riluzole oral suspension (brand name Tiglutik) is on the shortage list because EDW Pharma, Inc. is having trouble meeting the FDA's good manufacturing practice requirements — basically, there are standards the factory must follow to make sure the medicine is safe and made correctly, and right now there's a hold-up in meeting those standards. This affects specifically the Tiglutik 50 mg/10 mL oral suspension (NDC 70726-0303-1), and unfortunately there's no firm timeline yet for when it will be back — the estimated recovery date is listed as "to be determined."
The good news is that EDW Pharma's Teglutik 5 mg/1 mL oral suspension products are still listed as available, so not every riluzole suspension from this manufacturer is affected — just that specific 50 mg/10 mL Tiglutik product.
Based on the company-reported reason(s) and notes on file with the FDA for Riluzole Oral Suspension, summarized in plain English by HelloPharmacist. A drug can be short for more than one reason, and the FDA updates these as companies report changes.
What should I do if I take riluzole?
Riluzole oral suspension is currently on the FDA shortage list, and I want to walk you through what that means for your specific strength.
The two strengths are affected differently. The 5 mg/1 mL strength still has an available source from the manufacturer reporting this shortage, so if that is the one you take, supply is currently in place. The 50 mg/10 mL strength has no listed source right now and is marked unavailable, with an estimated recovery date that has not yet been set.
The reported reason relates to meeting good manufacturing practice requirements. One manufacturer is on this record, and this situation has lasted more than a year, so recovery timing remains uncertain for the 50 mg/10 mL strength. This is national, manufacturer-reported data and may not match what your local pharmacy actually has on hand.
Here is what I suggest, in order:
- Do not stop, skip, or change your dose on your own.
- If you take the 5 mg/1 mL strength, ask your pharmacy to order it — they can check wholesalers and suppliers.
- If you take the 50 mg/10 mL strength, talk with 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; pharmacies usually handle those calls.
- Ask your pharmacy to check other companies’ versions, other strengths, package sizes, and nearby stores — the options below are a starting point.
- If this is part of an ongoing or essential regimen (for example HIV, seizure, heart, transplant, diabetes or mental-health medicines), arrange continued supply before you run out rather than rationing doses.

Where else can I get riluzole?
FDA shortages are company-reported — a company only shows up on the shortage list if it told the FDA it has a supply problem, so not every company that lists riluzole oral suspensions is necessarily short. Below are the other listings in the current FDA NDC Directory that are not reported in shortage: the same medicine from companies that haven’t reported a problem (the reporting company is excluded), and other dosage forms. Some listings are repackagers, which relabel another company’s product. These may still be out of stock at your pharmacy, and only your prescriber or pharmacist can decide what’s right for you.
Other dosage forms of riluzole
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:
Therapeutic equivalents & pricing 5 productsclick to expand
Orange Book–rated equivalents of the affected strengths, with the latest NADAC price (a federal retail-acquisition benchmark, not your copay) and an evidence-based availability label. Cheapest first.
| Product | Manufacturer | Package | NADAC $/unit | AB rating | Availability |
|---|---|---|---|---|---|
| Tiglutik 50 mg/10mL | EDW | 2 bottles | — | AB | FDA listed |
| Teglutik 5 mg/mL | EDW | 2 bottles | — | — | FDA listed |
| Teglutik 5 mg/mL | EDW | 300 ml | — | — | FDA listed |
| Teglutik 5 mg/mL | EDW | 300 ml | — | — | FDA listed |
| Teglutik 5 mg/mL | EDW | 300 ml | — | — | FDA listed |
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.
Other drugs in the same treatment class
These are different medicines — not other versions of riluzole — that fall in the same broad treatment class (amyotrophic lateral sclerosis agents) . They are not automatic substitutes: they can differ in how they work, dosing, effectiveness, side effects and what they’re approved to treat. Do not switch on your own. This list is for information only — ask your prescriber or pharmacist whether any of them is appropriate for you.
