The FDA requires generic medications to demonstrate bioequivalence, meaning the same active ingredient, strength, dosage form, and route of administration as the brand-name product. A generic version of Insulin Glargine works the same way in the body as brand Lantus.
Because generics don't carry the original research and marketing costs, they usually cost far less while meeting the same FDA quality, strength, and purity standards. Read our generic vs. brand explainer →

Steps to save on Lantus
1. Compare cash prices
Compare Lantus cash prices across every US pharmacy before you fill — the same drug can cost several times more at one counter than another.
2. Check for a generic
Ask your prescriber or pharmacist about generic Insulin Glargine, which is usually far cheaper than brand Lantus and is FDA-rated therapeutically equivalent.
3. Apply a pharmacy coupon
Use a free discount coupon (such as GoodRx) at the pharmacy counter. Coupons and insurance cannot be combined, so compare the cash-coupon price against your copay.
4. Ask about patient assistance
Lantus has a manufacturer program (Sanofi Patient Connection (Lantus)) that may lower or cover your cost if you qualify.
5. Try mail-order
Mail-order pharmacies like Mark Cuban Cost Plus often price 90-day generic supplies below retail. Confirm the drug is in their catalog first.
