Major manufacturers of leucovorin?

Leucovorin calcium (folinic acid) is a common generic injectable, so many manufacturers produce it. Some of the major global and well-known producers include:

- Teva Pharmaceutical Industries
- Sandoz (Novartis)
- Viatris (formerly Mylan)
- Fresenius Kabi
- Sun Pharmaceutical Industries
- Cipla
- Dr. Reddy’s Laboratories
- Lupin Limited
- Zydus Cadila
- (Historically associated brands/providers in the US) Pfizer/Hospira

Availability varies by country and market, and many other regional or local manufacturers also produce leucovorin injections. If you tell me your country or market (and whether you need injectable or tablet forms), I can give a country-specific list of approved manufacturers.
