Toujeo biosimilar?

Short answer: there isn’t an approved biosimilar to Toujeo (insulin glargine U-300) yet. Biosimilars exist for insulin glargine U-100 (Lantus), not specifically for the U-300 formulation.

Biosimilars for insulin glargine (Lantus) you may see:
- Basaglar (insulin glargine) — a widely available biosimilar to Lantus
- Semglee (insulin glargine) — another biosimilar to Lantus
- Rezvoglar (insulin glargine) — a biosimilar to Lantus

Notes:
- Toujeo is a different formulation (U-300) with a distinct PK/PD profile from U-100 insulins, so a U-100 biosimilar is not the same as a Toujeo biosimilar.
- Swapping between insulins should only be done under medical supervision, with dose adjustments as needed.
