These rows are manufacturer reports to the FDA for Streptozocin Powder, For Solution — 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.

Why is Streptozocin Powder, For Solution in shortage?
Right now, the specific version of Zanosar (streptozocin) that Teva Pharmaceuticals makes — the 100 mg/1 mL powder for solution — is unavailable. Teva reported the reason as "other," which unfortunately means they didn't share a specific public explanation for why this is happening. There's also no firm timeline for when it might be back; their estimated recovery date is listed as "TBD," meaning to be determined.
It's worth knowing that this shortage report covers only Teva's 100 mg/1 mL package. The 1 g/10 mL version of Zanosar, made by ESTEVE Pharmaceuticals, is currently listed as available.
Based on the manufacturer-reported reason(s) and notes on file with the FDA for Streptozocin Powder, For Solution, 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 Streptozocin Powder, For Solution?
Streptozocin (also sold as Zanosar), a powder for solution, is currently on the FDA drug-shortage list. I want to walk you through what this means so you can find the strength you take.
The two strengths are affected differently. The 1 g/10 mL strength still has an available source from a manufacturer, so supply is reported for it. The 100 mg/1 mL strength currently has no available source — the maker that reported it, Teva, lists it as unavailable, with an estimated recovery date still to be determined. The reason on file is listed only as "Other." This shortage has lasted more than a year, and one of the two manufacturers on this record is still reporting supply.
Here is what I suggest, in order:
- Do not stop, skip, or change your dose on your own.
- If you take the 1 g/10 mL strength, ask your pharmacy to order it — pharmacies can check wholesalers and other manufacturers.
- If your strength is the 100 mg/1 mL, ask your prescriber or pharmacist about options, such as using a different available strength to make up the dose or a clinician-chosen alternative.
- Manufacturer contact numbers are listed on this page for reference; pharmacies usually handle these calls.
This is 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 Streptozocin Powder, For Solution?
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 Streptozocin Powder, For Solution 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.
Same medicine, other manufacturers (not reported short)
Same active ingredient, dosage form & route as the shortage (matched on the FDB HICL ingredient code), from makers that have not filed a shortage with the FDA:
