Insulin producing companies?

If you’re asking about who makes insulin, the main global manufacturers fall into a few groups:

- Major pharma companies that sell branded insulin products
- Eli Lilly and Company (USA)
- Humalog (insulin lispro)
- Humulin R/N (regular and NPH human insulins)
- Basaglar (insulin glargine) – a long-acting product (biosimilar to Lantus)
- Novo Nordisk (Denmark)
- NovoLog / NovoRapid (insulin aspart)
- Levemir (insulin detemir)
- Tresiba (insulin degludec)
- Sanofi (France)
- Lantus (insulin glargine)
- Toujeo (insulin glargine U-300)
- Apidra (insulin glulisine)

- Biosimilar and alternative producers (often in collaboration or for certain markets)
- Biocon Biologics (India) with Mylan/Viatris
- Semglee (insulin glargine) – a biosimilar to Lantus
- Viatris (global; formed from Mylan and Upjohn) markets biosimilar/similar insulin products in various regions
- In some regions, other companies such as Gan & Lee (China) and various Indian manufacturers produce insulin analogs or human insulin for domestic markets

Notes
- Brand names vary by country, and some biosimilars may be approved under different names in different markets.
- Availability depends on the country’s regulatory approvals and market licensing.
