Lantus® Vial for Type 1 and Type 2 Diabetes

Lantus® is a long-acting insulin used to help stabilize blood sugar. This page explains what it is, how to use it, and how to order with US delivery from Canada. You can also compare options and consider paying without insurance if that suits your situation.

What Lantus Is and How It Works

Lantus® contains insulin glargine, a long-acting basal insulin. After subcutaneous injection, microprecipitates form in the tissue and release insulin slowly. The result is a steady background effect with a reduced peak, helping support around-the-clock control when paired with mealtime insulin if needed.

YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

This medicine is supplied as a multi-dose vial for subcutaneous use only. Insulin glargine vial 10 mL is designed for once-daily basal coverage in most patients. It should not be used in an insulin pump or given intravenously. Follow your prescriber’s instructions and the official label.

Who It’s For

The treatment is indicated for adults with type 2 diabetes and for adults and children with type 1 diabetes who need basal insulin. Some people may use it alone for basal needs, while others use it with rapid-acting insulin at meals. Lantus Vial may not be appropriate if you have had a severe allergy to insulin glargine or any component of the product.

Avoid use during episodes of hypoglycemia. Speak with your healthcare professional if you have frequent lows, impaired kidney or liver function, or changes to other glucose-lowering medicines. Review the full prescribing information for additional contraindications and cautions.

Dosage and Usage

Use this medicine exactly as prescribed. Many patients inject it once daily at the same time each day. Your prescriber may adjust timing based on your regimen and blood glucose goals. Give injections subcutaneously in the abdomen, thigh, buttock, or upper arm, and rotate sites within the same region to reduce skin changes.

Do not mix or dilute this insulin with other products. Use only U-100 insulin syringes to draw doses from the vial. Check that the solution is clear and colorless; do not use if cloudy, thickened, or contains particles. Never share needles or syringes.

Practical tips: prepare your dose in a clean area, wipe the vial stopper with alcohol, draw air into the syringe equal to your dose, inject air into the vial, then withdraw the correct amount. Confirm the dose and remove air bubbles by tapping the syringe gently before injection. If you are also prescribed a mealtime insulin, your prescriber will explain how to coordinate the doses. For fast-acting meal coverage options, see your prescriber; some patients pair basal insulin with a rapid analog available as Novorapid Vial.

Strengths and Forms

The vial is a 10 mL multi-dose presentation of insulin glargine at U-100 concentration. Lantus vial 10 mL 100 U/mL is the commonly published strength and format. Availability can vary by market and stock.

Missed Dose and Timing

If you miss a dose, follow the guidance in the official label and contact your prescriber if you are unsure. In general, do not double up doses. If it is far from your usual time, you may take the dose and then resume your schedule the next day. If the next dose is near, you may be told to skip and continue as scheduled. Check your blood sugar more frequently, and be prepared to treat lows as directed.

Storage and Travel Basics

Unopened vials are typically stored in a refrigerator. Do not freeze; discard if frozen. An in-use vial can usually be kept at room temperature for a limited period per the label, away from heat and direct light. Keep all insulin out of the reach of children.

When you travel, carry your insulin and supplies with you, not in checked baggage. Use a travel case with cool packs to avoid heat extremes. Do not place vials directly against ice or gel packs. Bring your prescription label and a letter if advised by your clinician or airline. For trips across time zones, ask your prescriber how to adjust injection timing.

Product handling includes temperature-controlled handling when required. Always check the current patient information leaflet for exact storage instructions and in-use dating.

Pen Handling and Sharps Disposal

This product is supplied as a vial for use with U-100 insulin syringes. To protect yourself and others:

• New needle and syringe: always use a sterile, single-use needle and syringe.
• Clean technique: wipe the rubber stopper with alcohol before each puncture.
• Rotate sites: inject into fatty tissue and rotate areas to help prevent skin changes.
• Sharps safety: place used needles and syringes in an approved sharps container.
• Local rules: follow your local or state guidance for sharps disposal.

Benefits

This basal insulin provides a smooth background effect that can help limit peaks and dips compared to shorter-acting options. Once-daily dosing simplifies routines for many people. A vial format offers dosing flexibility and can fit multiple care settings. When paired appropriately with mealtime options, the therapy supports comprehensive glucose management alongside nutrition, activity, and monitoring.

Side Effects and Safety

• Low blood sugar: shakiness, sweating, confusion, headache, or irritability.
• Injection site reactions: redness, itching, or mild swelling.
• Weight gain or fluid retention: may occur with insulin use.
• Skin changes: lipodystrophy or skin thickening at injection sites.

Serious effects can include severe hypoglycemia, hypokalemia, or generalized allergic reactions. Seek urgent help for trouble breathing, swelling of the face or throat, or severe dizziness. The risk of hypoglycemia may increase when used with sulfonylureas or other insulins. Review the full label and speak with a clinician about medical history, including kidney or liver issues.

Drug Interactions and Cautions

Medicines that may affect glucose control include steroids, certain diuretics, oral contraceptives, thyroid drugs, atypical antipsychotics, and some HIV therapies. Alcohol can raise or lower blood glucose and may blunt your awareness of lows. Beta blockers may mask symptoms of hypoglycemia. GLP-1 receptor agonists and SGLT2 inhibitors can also influence overall requirements. Share a full medication list with your prescriber.

Do not change your dose without medical guidance. Confirm you are using the correct insulin, strength, and syringe to prevent errors. Do not use this product in an insulin pump or for diabetic ketoacidosis.

What to Expect Over Time

With regular, same-time daily use, many people experience steadier fasting and between-meal readings. Your prescriber may adjust the dose based on patterns from your glucose logs and A1C results. Individual needs vary, and nutrition, activity, stress, and illness can affect targets. Keeping a consistent routine, rotating injection sites, and refilling before you run out can support safer use.

Options we carry include the biosimilar glargine pen Basaglar Kwikpen and high-strength glargine Toujeo Doublestar. These alternatives differ by device and labeled dosing guidance. Discuss transitions with your clinician before switching.

Availability and Substitutions

Patient Suitability and Cost-Saving Tips

Good candidates include adults with type 2 diabetes who need basal coverage and people with type 1 diabetes who require a background insulin with rapid-acting mealtime coverage. This therapy is not for diabetic ketoacidosis and not for pump use. Those with recurrent severe hypoglycemia or hypersensitivity to components may not be candidates.

To manage expenses, ask your prescriber about multi-month supplies if appropriate. Combine refills with other diabetes supplies to reduce separate shipments. Set reminders so you do not run out unexpectedly. Where available, Generic insulin glargine vial cost may differ from brand devices; your prescriber can advise on medically suitable alternatives.
