Insulin glargine yfgn cost?

Do you mean a specific brand of insulin glargine (for example Lantus, Basaglar, or Toujeo), and which country are you in? The term “yfgn” isn’t a standard product code I recognize, so I want to make sure I’m talking about the right product.

Prices vary a lot by country, pharmacy, dosage form (vial vs. prefilled pen), and whether you have insurance. Here are rough US ballpark ranges to give you an idea, but these are not exact prices and can change:

- Lantus (insulin glargine U-100) vial: roughly $300–$400+ per 10 mL bottle.
- Lantus SoloStar pens (5 pens per carton, U-100): roughly $350–$500 per carton.
- Basaglar (biosimilar glargine U-100) vial: roughly $250–$350 per 10 mL bottle.
- Basaglar pens (U-100) carton: roughly $350–$450.
- Toujeo (insulin glargine U-300) pens: typically higher, around $500–$650 per 3 mL pen.

If you have insurance, your out-of-pocket is often much lower. There are also discount programs and coupons that can reduce costs.

If you tell me:
- your country and city,
- the exact product (brand or code) and whether you need a vial or a pen,
- and whether you have insurance or plan to pay cash,

I can give you a more tailored estimate and point you to resources (like GoodRx or local pharmacy prices) to check current prices.
