Rifampin Injection shortage
Rifampin 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; Demand increase for the drug. This page was last refreshed from FDA data on Sep 17, 2026.
Rifampin injection is in shortage, with one maker stopping it for good, another not expected to recover until late 2026, and the 600 mg/10 mL vial currently having no available source. Some 600 mg supply may still be found through wholesalers from the one manufacturer that has not reported a shortage.
Don’t stop or change your therapy on your own — talk with your prescriber about the plan that fits you, and ask your pharmacist what’s actually available (see options).

These rows are manufacturer reports to the FDA for Rifampin 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 Rifampin Injection? options further down this page.
Why is Rifampin Injection in shortage?
Rifampin injection 600 mg is on the shortage list because of a few things happening at the same time. Sanofi-Aventis has permanently stopped making their brand-name version, Rifadin Injection 600 mg, entirely — so that product is gone from this manufacturer for good. Mylan Institutional (a Viatris company) still makes a 600 mg version, but higher-than-usual demand has outpaced their supply, and they don't expect to catch up until the fourth quarter of 2026 (that's October–December 2026). Fresenius Kabi USA also makes a 600 mg version, and while it's still being made, supplies are limited right now — their guidance is to check with wholesalers to see what inventory is available.
So in short, one manufacturer permanently stopped making it, another is behind due to a big jump in demand, and the third has only a limited amount on hand. That combination is what's driving this shortage.
Based on the manufacturer-reported reason(s) and notes on file with the FDA for Rifampin 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 Rifampin Injection?
Rifampin Injection is currently on the FDA drug-shortage list, so I want to walk you through what that means for the strength you use.
There are two strengths on this record, and they are in different situations. The 600 mg strength still has an available source right now, though supply is limited. The 600 mg/10 mL strength has no available source at present and is reported as discontinued by its manufacturer.
The reported reasons include a demand increase, a manufacturer discontinuing the product, and "other" supply issues. Of three manufacturers on this record, one still reports supply for the 600 mg strength. One maker of the 600 mg lists an estimated recovery of Q4 2026. This shortage has lasted over a year, so patience may be needed.
Here is what I suggest:
- Do not stop, skip, or change your dose on your own.
- If you use the 600 mg strength, ask your pharmacy to order it — pharmacies can check wholesalers and other manufacturers for inventory.
- If you use the 600 mg/10 mL strength, which is reported discontinued, this problem may be lasting, so talk with your prescriber about a clinician-chosen option.
- Manufacturer contact numbers are listed on this page for reference; pharmacies usually handle those calls.
This reflects national, manufacturer-reported data and may not match your local pharmacy's actual stock.
- 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 Rifampin 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 Rifampin 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.
Alternative dosage forms of Rifampin
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 4 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 |
|---|---|---|---|---|---|
| Rifadin IV 600 mg/10mL | Sanofi-Aventis | 1 vial | — | AP | FDA listed |
| Rifampin 600 mg | Hikma | 1 injection | — | AP | FDA listed |
| Rifampin 600 mg | Fresenius | 1 vial | — | AP | FDA listed |
| Rifampin 600 mg/10mL | Mylan | 1 vial | — | AP | 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 Rifampin Injection — that fall in the same broad treatment class (antitubercular antibiotics) . 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.
