Leucovorin maker?

Which company makes leucovorin (folinic acid) in the US?

Leucovorin is a branded and generic medicine (folinic acid). Multiple manufacturers can supply it, depending on the exact product strength and formulation (for example, injection vs tablets) and which market (US vs other countries) you mean.

How to find the specific manufacturer you need

To identify the exact “maker” for the leucovorin product you’re asking about, you typically need at least one of the following:
- The product name (brand vs generic)
- Dosage form (injection, tablet, etc.)
- Strength (mg per tablet/vial)
- Labeler/ND C (National Drug Code) on the box or vial

With the NDC, you can match the product to its labeler/manufacturer for that specific listing.

What I need from you to answer “the maker” precisely

Which leucovorin are you referring to (please share any one: brand name, NDC, dosage form, or strength)? Once you provide that, I can point to the specific manufacturer/labeler for that product.
