Lantus® Vial for Diabetes

Insulin glargine is a long-acting insulin that helps stabilize blood sugar. The vial format supports once-daily basal dosing for adults and children who need steady coverage. This page explains safe use, access options, and US delivery from Canada so you can plan confidently without insurance.

What Lantus Is and How It Works

Lantus® contains insulin glargine, a modified human insulin designed for slow, consistent release. It forms microprecipitates in the subcutaneous tissue that release insulin steadily over many hours. That profile supports basal coverage between meals and overnight. Do not mix or dilute this medicine with other insulins. For background on this class, see What Is Long Acting Insulin.

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

The formulation is supplied as a multi-dose vial. It is injected subcutaneously in the abdomen, thigh, or upper arm, rotating sites to reduce skin changes. Ask your prescriber which schedule aligns with your plan.

Who It’s For

This treatment is indicated to improve glycemic control in adults with type 2 diabetes and in adults and pediatric patients with type 1 diabetes. Explore related guidance for Type 1 Diabetes and Type 2 Diabetes.

It is not for episodes of diabetic ketoacidosis. People with recurrent severe hypoglycemia, significant renal or hepatic impairment, or allergy to any ingredients should review risks with a clinician. Use in pregnancy or while breastfeeding should be guided by the official label and your prescriber.

Dosage and Usage

Basal insulin is commonly injected once daily at the same time each day. Some people may use different schedules per the label. Your prescriber will determine the starting dose and any adjustments based on glucose monitoring. Give injections subcutaneously only, never intravenously or in an insulin pump. Rotate injection sites within a region to limit lipodystrophy.

Do not mix this medicine with other insulins or use it in combination syringes. If you also use rapid-acting insulin for meals, administer the injections separately and follow the timing your prescriber recommends. Review technique, priming of syringes, and site care at each visit. For device comparisons, see Types Of Insulin Pen if you are considering pen options for other products.

Strengths and Forms

Availability can vary by pharmacy and date. Commonly supplied presentation:

Some patients refer to this as the Lantus 10 mL vial U-100 when discussing the specific bottle in a regimen.

Missed Dose and Timing

If you miss a dose, take it as soon as you remember on the same day, then resume your regular schedule the next day. Do not double to make up a dose. If the timing is unclear or several doses are missed, contact your prescriber or follow the official label guidance.

Storage and Travel Basics

Unopened vials should be refrigerated per the label. Keep away from heat and direct light. Do not freeze; discard if frozen. Once in use, a vial may be kept at room temperature as permitted by the label and used within the in-use period stated there. Always replace the cap after each use.

When traveling, carry supplies in a protective case. Keep insulin with you rather than in checked baggage. Pack extra syringes, alcohol swabs, and a backup vial when possible. A copy of your prescription and a travel letter can help with security screening. Many patients use a sharps container for used needles and syringes in transit.

Benefits

This basal insulin provides steady, long-acting coverage that complements meal-time insulin when needed. Once-daily dosing helps simplify routines for many people. Predictable absorption supports overnight control and between-meal coverage. It can be used across age groups where indicated on the label, allowing consistent therapy as needs change.

Side Effects and Safety

• Low blood sugar: shakiness, sweating, confusion, or headache
• Injection site reactions: redness, pain, or swelling
• Weight gain or mild edema
• Skin changes at injection sites
• Rash or itching

Severe hypoglycemia can occur and may require assistance. Serious allergic reactions are rare but possible. Insulin may shift potassium and contribute to hypokalemia. Fluid retention can occur with certain glucose-lowering medicines such as thiazolidinediones. Contact a clinician urgently for signs of severe low blood sugar or an allergic reaction.

Drug Interactions and Cautions

Medicines that may increase or decrease insulin needs include steroids, certain antipsychotics, thyroid medicines, hormonal contraceptives, and some antivirals. Alcohol can raise or lower glucose. Beta blockers may mask adrenergic symptoms of hypoglycemia. Thiazolidinediones used together can increase fluid retention. Always share a full medication list with your healthcare professional. The official label provides additional details.

What to Expect Over Time

Many people notice smoother fasting and between-meal readings after consistent daily use. Dose adjustments are often made gradually, guided by home glucose data and A1C trends. Staying consistent with timing, meals, and activity helps your prescriber assess patterns. For background on therapy planning, see Type 1 Diabetes Insulin. Keep backup supplies on hand and set reminders to stay on schedule.

Compare With Alternatives

Another long-acting option is insulin glargine U-300, supplied as a pen device, such as Toujeo Doublestar Prefilled Pen. Some prescribers use premixed insulins in specific cases; these combine basal and bolus components but are not direct substitutes for a pure basal vial. An example we carry is Humalog Mix Cartridges. Your clinician will decide if a change is appropriate.

Patient Suitability and Cost-Saving Tips

This therapy suits people who need a long-acting basal insulin and are comfortable drawing up doses with U-100 syringes. It is not for DKA or for use in infusion pumps. People at higher risk of hypoglycemia may need closer monitoring and tailored plans.

• Multi-month supply: reduce pharmacy trips and potential gaps
• Refill reminders: set calendar or app alerts
• Syringe sizing: match U-100 syringes to the vial
• Travel kit: pack spare syringes and a backup vial
• Budget planning: ask about cash-pay options and discounts

For some, a prescriber-approved switch in device or schedule can reduce out-of-pocket costs. You may also order insulin glargine vial alongside other diabetes supplies to consolidate fulfilment and save time.
