Price of lantus insulin?

Price varies a lot by country, pharmacy, dosage form (vial vs. prefilled pen), and whether you have insurance. Here are rough U.S. benchmarks to give you an idea:

- Lantus (insulin glargine) 10 mL vial (100 units/mL): roughly $275–$350 for cash price.
- Lantus SoloStar pen (3 mL, 300 units per pen): roughly $400–$550 per pen.

If you have insurance or a discount program, your out-of-pocket could be much lower. Biosimilars (-basaglar, semglee) can be cheaper than Lantus in many cases.

Prices can differ in other countries due to pricing rules and subsidies. To get an exact current price for you, tell me:
- your country/region
- whether you want a vial or a pen
- the specific strength/quantity you need (e.g., 100 units/mL, 300 units per pen)

I can help you look up current cash prices at common pharmacies or point you to discount sources (like GoodRx) if you’d like.
