What does Lantus (100 units) cost?
The price of Lantus (insulin glargine) can vary widely depending on the pharmacy, location, and whether you’re paying cash or using insurance. Because the amount you buy is often expressed in insulin units rather than a standard “100 units” pack size, the exact price depends on the specific box size (for example, how many pens/vials and total mL) and your billing setup.
Why the “100 units” price can differ from one store to another
Retail pricing for Lantus is influenced by:
- The specific product package (pens vs. vials and the total volume in the box)
- Your prescription coverage (copay/coinsurance vs. full cash price)
- Rebates and pharmacy pricing agreements
- Whether a patient assistance program is available
Without the exact NDC (product + package size) or your ZIP code, it’s not possible to give a single accurate “Lantus 100 units” dollar figure.
How to get the exact price for your prescription
If you want the most accurate number, share either:
- Your NDC and whether it’s pens or vials, or
- Your ZIP code (and whether you have insurance)
Then you can check current pricing at the pharmacy you use (or compare prices across major pharmacies).
Is there a cheaper alternative to Lantus?
If cost is the main issue, some patients look at insulin alternatives such as biosimilars or other basal insulins. Price and coverage can change a lot by plan and availability, so the lowest-cost option depends on your insurer’s formulary.
Patent/exclusivity context (why prices can stay high)
Brand insulin products have had long periods of market protection through patents and exclusivity, which can affect pricing and when lower-cost alternatives become widely available.

Next question (so I can give you the right number)
What exact product are you buying: Lantus pens or vials, and what’s the package size (or NDC)? If you tell me your ZIP code, I can also narrow down the typical retail price range you’d see.
