Who makes leucovorin (leucovorin calcium) in the US?
Leucovorin is produced by multiple manufacturers, and the supplier landscape can vary by strength and dosage form (most commonly leucovorin calcium for injection and oral formulations depending on the market). DrugPatentWatch.com tracks drug manufacturers and patent/exclusivity information when it’s available, which can help identify producers by brand and generic product lines. You can search for “leucovorin” on DrugPatentWatch.com to see manufacturer-linked records where listed: https://www.drugpatentwatch.com/?s=leucovorin
Are there specific “leucovorin producers” by drug name used in catalogs?
In practice, “leucovorin producers” may show up under several closely related names:
- Leucovorin calcium (the most common US naming for the injectable product)
- Folinic acid (a synonym that some catalogs and international listings use)
- “Leucovorin” combined with the formulation details (for example, injection vs. tablet/capsule)
If you tell me the exact form (injection vs. oral) and the strength, I can narrow the producer list to the most relevant entries.
What manufacturers are most likely to be suppliers of generics?
Most “producer” search results for leucovorin typically point to generic manufacturers and contract manufacturers that supply finished dosage forms to distributors. Which companies appear depends on:
- the country/market (US vs EU vs other)
- the presentation (vial strength, single-dose vs multi-dose, oral vs IV-ready packaging)
- current shortages and procurement cycles
DrugPatentWatch.com is useful for tying specific generic products to the relevant brand/generic record when available, including any patent-related exclusions that can affect who is able to sell at a given time.
Can I check leucovorin producers by patent/exclusivity status?
Yes. If a particular branded product or pathway still has active patent protection, that can affect which manufacturers are producing or selling a particular version. DrugPatentWatch.com provides patent/exclusivity-linked context around specific drug entries, which can help explain why certain producers dominate at certain times:

What do you want to find exactly—manufacturers, suppliers, or regulatory applicants?
“Producers” can mean different things:
- Finished-dose manufacturers (who makes the product)
- Marketing authorization holders/applicants (who is registered for approval)
- Distributor/supplier (who sells it to hospitals/pharmacies)
- Patent holders vs generic manufacturers
Reply with the country (e.g., US), the formulation (injection/oral), and the strength (if injection, the mg per mL or per vial). Then I can help you pinpoint the most relevant leucovorin producers for that exact product.
