Lantus pen cost?

Prices for Lantus pens vary a lot by country, pharmacy, dosage form, and your insurance. I can give a rough idea, but for an exact price you’d need to check a local pharmacy or your insurer.

General ballpark ( United States, branded Lantus SoloStar 100 U/mL, 3 mL pen):
- A single pen is often in the low hundreds before insurance.
- A carton of five pens can be several hundred up to roughly $600–$900 depending on discounts and where you buy it.

If you’re outside the US, prices can be quite different.

Ways to lower cost:
- Check current prices with nearby pharmacies or use discount programs (GoodRx or similar).
- See if your insurer covers a cheaper insulin or a preferred formulary option.
- Ask your prescriber about a cheaper option like Basaglar (a biosimilar insulin glargine) if appropriate for your regimen.
- Ask about manufacturer patient-assistance programs or coupons.
- Consider your available forms (pen vs vial) if a vial option might be cheaper for you.

If you tell me your country/city and whether you have insurance, I can help narrow down a closer estimate or point you to specific discount options.
