Metronidazole Injection shortage
Metronidazole Injection is currently listed in shortage by the FDA. The FDA lists 4 affected products. The reported reason: Other; Discontinuation of the manufacture of the drug. This page was last refreshed from FDA data on Sep 22, 2026.
Gland Pharma is permanently stopping its metronidazole injection, creating a shortage that has lasted over a year. The 500 mg/100 mL strength is still listed by other manufacturers not reporting a shortage, including Baxter Healthcare, Civica, WG Critical Care, and Amneal Pharmaceuticals.
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 Metronidazole Injection — 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 Metronidazole Injection? options further down this page.
Why is Metronidazole Injection in shortage?
Metronidazole injection (500 mg/100 mL) is on the shortage list for a couple of different reasons depending on the manufacturer. Gland Pharma Limited has permanently stopped making their version of this product altogether — that's the "discontinuation" you may see mentioned. On top of that, two other suppliers — Hospira and Sagent Pharmaceuticals — currently have only limited amounts available, with Sagent's supply expected to recover around August 2026. The reason given for those two is listed as "other," meaning the specific cause wasn't publicly shared.
It's worth knowing that this shortage report reflects only the manufacturers who filed it. Baxter Healthcare's version — Flagyl I.V. RTU in a plastic container, also 500 mg/100 mL — is reported as available through this same filing, so not every supplier of this product is in the same situation.
Based on the manufacturer-reported reason(s) and notes on file with the FDA for Metronidazole Injection, 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 Metronidazole Injection?
Metronidazole injection is currently on the FDA shortage list. This is a medicine given through a vein, usually in a hospital or clinic setting.
There is only one strength involved, 500 mg/100 mL, and that strength still has an available source. Two of the three manufacturers on this record continue to report supply, so no strength is completely without a source right now.
The reported reasons include one manufacturer (Hospira/Sagent) discontinuing its version, with an estimated recovery noted for August 2026, and a separate discontinuation from another maker. Because this affects only certain suppliers—not every company that makes this medicine—other manufacturers may still be able to fill the gap. Overall supply risk is rated low.
Here is what you can do:
- Do not stop, skip, or change your treatment on your own.
- Ask your pharmacy or care team to order the 500 mg/100 mL strength, since a source is still available; they can check wholesalers and other manufacturers.
- The same medicine may be available from other makers such as Baxter, WG Critical Care, Civica, or Amneal—your pharmacy may be able to source one, though it may not be in local stock.
Manufacturer contact numbers are listed on this page for reference. This reflects national data and may not match your local supply.
- 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 Metronidazole Injection?
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 Metronidazole Injection 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.

Other drugs in the same treatment class
These are different medicines — not other versions of Metronidazole Injection — that fall in the same broad treatment class (anaerobic antiprotozoal-antibacterial 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.
