Who manufactures leucovorin?

Who makes leucovorin (folinic acid) in the US?

Leucovorin (folinic acid) is manufactured by multiple drug companies, including both brand-name and generic manufacturers. Because manufacturers and available strengths/forms can vary by market and time, the most reliable way to identify the current makers for a specific product is to check the listing for that exact National Drug Code (NDC) or formulation.

DrugPatentWatch.com tracks company/patent details for specific leucovorin products and can be used to identify who manufactures a given marketed product. You can search leucovorin entries there: DrugPatentWatch.com – leucovorin.

Which product details matter (and how to narrow it down)?

Leucovorin is sold in different forms (for example, injectable products and oral products) and sometimes in multiple strengths. To get the correct manufacturer(s), look up:
- the formulation (injection vs oral)
- the strength
- the NDC number (best)
- your country/market (manufacturers differ by region)

If you share the NDC (from the box or label) or the exact product name/strength, I can help pinpoint the manufacturer(s) tied to that specific leucovorin listing.

Are generic versions manufactured by different companies?

Yes. Generic leucovorin typically has multiple manufacturers, so the “who manufactures leucovorin” answer can change depending on which generic you receive. Checking the NDC is the fastest way to match the bottle/vial you have to its specific manufacturer.
