Pharmacy pricing is not regulated in the United States, so retailers set their own cash prices. Large retailers like Walmart and Costco typically offer lower prices on generics because they use prescriptions as a traffic driver. Chain pharmacies like CVS and Walgreens tend to charge significantly more.

Ask for the generic. If your doctor prescribed the brand-name Lantus, ask your pharmacist whether the generic Insulin Glargine is available. In most states, pharmacists can substitute a generic unless the prescriber writes 'dispense as written.'
Use a discount card. Services like GoodRx, SingleCare, and WellRx can sometimes negotiate prices lower than retail cash. The estimated GoodRx low for Insulin Glargine is around $68.00.
Coverage depends on your specific plan and formulary. Most diabetes medications are covered under standard health insurance, typically in Tier 1 or Tier 2. If your copay is higher than the cash price above, it may be cheaper to pay out of pocket — ask your pharmacist to compare.
