Terms & Conditions of Program
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
LANTUS (insulin glargine) is a medication prescribed to treat patients with type 1 and type 2 diabetes mellitus. People with diabetes have blood sugar levels that are too high because they do not produce enough insulin, or they have a resistance to insulin. LANTUS and other insulin products return high blood sugar levels to normal.

Inject LANTUS insulin once daily as directed by the physician.
Rotate injection sites to avoid side effects like lipodystrophy and injection site reactions.
LANTUS contains insulin glargine, which is a type of insulin that has been modified to be long-acting. LANTUS lasts for about 24 hours in most people and can be injected once daily.
LANTUS should not be used as meal-time insulin.
Tell your doctor or pharmacist if you are taking any of the following medications. They can affect blood sugar, and the dose of LANTUS may need to be adjusted:
Store LANTUS in the refrigerator (36°F-46°F [2°C-8°C]) before opening. Once a vial is opened, it can be kept at room temperature for 28 days and then discarded. For LANTUS pens, several come in a box, and only one should be opened at a time. They can also be stored at room temperature for 28 days after opening.
Only change the dosage of LANTUS under close medical supervision.
Changes in medication, meals, physical activity, and other medical conditions may change your insulin needs.
LANTUS insulin may have the following side effects:
Lantus [package insert] Bridgewater, NJ: Sanofi-Aventis; 2018
When does Lantus start working and how long does it last?
Lantus begins working within 1 to 2 hours after injection and maintains a steady effect for about 24 hours. It has no peak, which helps reduce the risk of hypoglycemia between meals or overnight.
Can I use Lantus with other diabetes medications?
Yes. Lantus is often used in combination with:
Rapid-acting insulin for mealtime coverage (especially in type 1 diabetes)
Oral medications like metformin, sulfonylureas, or DPP-4 inhibitors in type 2 diabetes
Always coordinate combinations under a doctor’s supervision.
What happens if I inject Lantus into a muscle instead of under the skin?
Injecting into a muscle (intramuscularly) can cause faster absorption, increasing the risk of low blood sugar. Lantus is formulated for subcutaneous use only — inject into fatty tissue, not muscle.
Can I drink alcohol while using Lantus?
Alcohol can affect blood sugar levels, potentially causing hypoglycemia, especially when taken on an empty stomach. It’s best to limit alcohol intake and monitor blood sugar more frequently if you drink.
What should I do if I accidentally inject too much Lantus?
Seek medical attention immediately. An overdose can lead to severe hypoglycemia, which may cause symptoms like dizziness, confusion, seizures, or unconsciousness. Keep fast-acting carbs (e.g., glucose tablets, juice) available.
Can Lantus be used in children?
Yes, but with limitations. Lantus is approved for use in:
Children =6 years old with type 1 diabetes
Adults with type 2 diabetes (not approved for children with type 2)
Pediatric dosing requires careful monitoring.
Are there generic or biosimilar versions of Lantus?
Yes. Insulin glargine is available as:
Basaglar – a follow-on biologic
Semglee – an interchangeable biosimilar approved by the FDA
These provide similar effectiveness at a potentially lower cost.
Can Lantus be injected in the same spot every day?
No. Repeatedly injecting into the same spot can cause lipodystrophy (fatty tissue changes) which may interfere with insulin absorption. Rotate injection sites within the same general area (abdomen, thigh, upper arm).
Is Lantus affected by exercise?
Yes. Physical activity increases insulin sensitivity and can lower blood glucose, raising the risk of hypoglycemia. Monitor levels before and after exercise, and consider adjusting food intake or insulin dose as advised by your doctor.
What devices can I use to inject Lantus?
Lantus is available in:
SoloStar prefilled pens
Vials for use with insulin syringes
The pen option is often preferred for ease, precision, and convenience. Always follow proper usage instructions for the chosen device.
