Who makes leucovorin (the active ingredient)?
Leucovorin (also sold as “leucovorin calcium” in many markets) is made by multiple pharmaceutical manufacturers, typically under generic and brand-name products.
Which brand names use leucovorin?
Common market names for leucovorin products often include leucovorin calcium generics and, in some countries, branded versions. Availability depends on the country and whether you mean the injectable or oral form.
Can you point to a specific manufacturer list for your country?
Manufacturers vary by country, dosage form (injection vs oral), and strength. If you tell me your country (and whether you need injection or tablets/solution), I can narrow down the manufacturers that actually supply leucovorin where you are.

What I need to give you an exact answer
Reply with:
1) Your country (US, UK, Canada, etc.)
2) Form (IV/IM injection vs oral)

Then I can list the specific companies that make leucovorin for that market.
