Lantus® Vial for Diabetes

Insulin glargine is a long-acting basal insulin for blood glucose control. This page explains the vial presentation, how it is used, and important safety points. We also outline how to access the medicine with US shipping from Canada and typical options for those paying without insurance.

What Lantus Is and How It Works

Lantus® contains insulin glargine, a recombinant human insulin analog. It forms microprecipitates after subcutaneous injection, releasing small amounts of insulin over many hours. The result is a relatively flat, peakless basal effect that can help maintain steadier fasting and between-meal glucose levels. It is not a mealtime insulin.

This medicine is indicated for adults with type 2 diabetes and for adults and pediatric patients with type 1 diabetes when used with mealtime insulin. The treatment should be injected subcutaneously, typically once daily at the same time each day per the approved label. It is not for intravenous use and should not be used in an insulin pump.

Who It’s For

This basal insulin is used to improve glycemic control in adults with type 2 diabetes. It is also used in type 1 diabetes as the background insulin alongside rapid-acting prandial insulin. Patients who need a once-daily basal option may be candidates.

People with a history of severe hypoglycemia, hypersensitivity to insulin glargine, or local reactions to excipients should discuss risks with their clinician. An insulin glargine vial may not be appropriate for individuals unable to recognize or treat low blood sugar. Use during pregnancy or breastfeeding requires individualized counseling per official labeling.

Dosage and Usage

Follow your prescriber’s instructions and the product’s approved labeling. This therapy is generally injected once daily at the same time. In type 1 diabetes, it is used with a rapid-acting insulin for meals. In type 2 diabetes, it may be used alone or with other non-insulin agents and, if needed, with prandial insulin. Do not mix or dilute this insulin with other products.

Use the vial with a compatible U-100 insulin syringe. Inspect the liquid before each use. It should be clear and colorless, with no particles. Inject into subcutaneous tissue of the abdomen, thigh, or upper arm, rotating injection sites to reduce the risk of lipodystrophy.

Strengths and Forms

This product is supplied as a multi-dose vial for subcutaneous use. Each vial typically contains 10 mL of U‑100 insulin glargine solution. Availability may vary by dispensing pharmacy and jurisdiction.

• Vial: 10 mL of solution for injection
• Concentration: 100 units per mL (U‑100)

Related basal options are available in cartridge and prefilled pen formats under other brands. Explore our category for class options under Long-Acting Insulin. For search clarity in this section, we note the exact term Lantus 100 units/mL vial.

Missed Dose and Timing

If you miss a once-daily basal dose, follow the instructions in the official label or contact your healthcare provider for guidance. Generally, take it as soon as remembered if it is not close to the next scheduled dose. Avoid doubling doses, which may increase hypoglycemia risk.

Try to keep injections at the same time each day. Set reminders on your phone or calendar to support consistent use. For search clarity in this section, this exact term appears once: insulin glargine 10 mL vial.

Storage and Travel Basics

Unopened vials should be stored refrigerated. Do not freeze. If a vial has been frozen, do not use it. After first use, the vial may be kept at room temperature or refrigerated for up to the period specified on the label, commonly 28 days. Keep away from direct heat and light. Always check the solution; do not use it if cloudy, discolored, or containing particles.

When traveling, carry your insulin and supplies in a dedicated bag. Keep the vial with you in a cabin bag, not in checked luggage. Use a cooling pouch or insulated container with gel packs to maintain safe temperatures, but avoid placing the vial directly against ice. Bring your prescription label and a copy of your prescription for security checks. For search clarity in this section, one exact phrase appears: insulin glargine 100 units/mL vial.

Pen Handling and Sharps Disposal

This vial is used with disposable insulin syringes. Use a new sterile needle and syringe for each injection. Draw the correct dose carefully and remove air bubbles as instructed by your care team.

Dispose of used needles and syringes in an FDA-cleared sharps container. If unavailable, use a heavy-duty household container with a tight-fitting, puncture-resistant lid until you can transfer to an approved option. Follow local regulations for sharps disposal. Never flush or throw loose needles into household trash.

Benefits

As a basal insulin, this treatment provides steady background insulin activity over 24 hours for many users. A once-daily schedule can simplify routines compared with multiple basal doses. The vial format may help patients who prefer syringe dosing or need flexible quantities for dose titration.

The relatively flat profile can reduce variability between injections. Using consistent timing and site rotation may support more predictable results. Always align your plan with your prescriber’s guidance.

Side Effects and Safety

• Low blood sugar: shakiness, sweating, headache, dizziness, irritability
• Injection site reactions: redness, pain, or swelling
• Edema: fluid retention may occur
• Weight gain: possible with insulin therapy
• Allergic reactions: rash or pruritus
• Lipodystrophy: skin thickening or pitting at injection sites

Serious but less common risks include severe hypoglycemia and hypokalemia. Seek urgent medical help for severe allergic reactions, trouble breathing, or persistent, severe low blood sugar. Do not mix this insulin with other insulins or inject it intravenously. Avoid accidental use in an insulin pump unless directed by the approved labeling, which generally does not support pump use for this formulation.

Drug Interactions and Cautions

Numerous medications can increase or decrease insulin requirements. Agents that may raise blood glucose include corticosteroids, certain diuretics, and some atypical antipsychotics. Agents that may lower blood glucose include non-selective beta blockers, ACE inhibitors, and salicylates. Beta blockers may also blunt the warning symptoms of hypoglycemia.

Use caution when combining insulin with thiazolidinediones, which can increase fluid retention and worsen heart failure in susceptible patients. Alcohol can increase hypoglycemia risk. Review all prescription medications, OTC products, and supplements with your clinician.

Patients transitioning from another basal insulin should follow prescriber instructions and the official label. For background on concentrated basal insulin, see our explainer Toujeo Overview.

What to Expect Over Time

Many patients see steadier fasting glucose with regular daily use. Adjustments may be needed when diet, activity, illness, or concomitant medications change. Your clinician may refine the regimen over time based on glucose patterns.

Adherence matters. Take the dose at a consistent time daily, rotate sites, and keep records of readings as instructed. Carry a source of fast-acting carbohydrate in case of low blood sugar. Wear medical identification indicating insulin use, especially during travel.

Compare With Alternatives

Other basal insulins include biosimilar or follow-on insulin glargine and different analogs. A follow-on glargine option is available; see Buy Basaglar Online. An ultra–long-acting analog option is available in a pen device; consider Flextouch Pens. Some patients may also discuss detemir or NPH-based regimens with their prescriber.

Choice depends on clinical history, dose needs, device preference, and insurance or cash-pay considerations. Do not switch products without prescriber guidance.

Patient Suitability and Cost-Saving Tips

This treatment may suit adults and children needing a steady basal insulin. Patients with frequent severe hypoglycemia, unrecognized lows, or significant injection site issues should discuss risks. Those requiring concentrated insulin may need a different product under clinician guidance.

Consider larger-quantity fills if appropriate and allowed by your prescription. Align refills with clinic visits to avoid lapses. Set digital reminders for nightly dosing. If paying cash, compare multi-vial orders and plan ahead to reduce per-vial costs, when permitted by local rules.
