Lantus Solostar Pens® Insulin Glargine U-100 Prefilled Basal Insulin

What Lantus Is and How It Works

Lantus® SoloStar pens deliver insulin glargine U-100, a long-acting basal insulin for adults with type 1 or type 2 diabetes, and for pediatric patients with type 1 diabetes. It provides steady 24-hour background insulin with once-daily dosing. Many people compare Lantus Solostar Pens without insurance when budgeting ongoing diabetes care. YouDrugstore is a licensed Canadian pharmacy in Manitoba. Our pharmacists review prescriptions before dispensing, and you can order online with support from our friendly customer-service chat during posted office hours. We partner with vetted, licensed international pharmacies when needed to offer authentic brands, broad selection, and fair pricing.

Insulin glargine forms microprecipitates under the skin after injection. It then releases small, consistent amounts of insulin over the day and night. This smooth profile helps manage fasting and between-meal glucose and reduces peaks and valleys compared with intermediate-acting human insulin.

Dosage and Usage

Use Lantus® SoloStar once daily at the same time. Your prescriber will set your dose and adjust it based on glucose readings and goals.

• Typical adult type 2 starting dose: 10 units once daily, or about 0.2 units/kg.
• Type 1 therapy uses a total daily insulin dose split into basal and mealtime insulin.
• Prime the pen as directed (usually 2 units) before each injection.
• Inject into the abdomen, thigh, or upper arm. Rotate sites to reduce skin changes.
• Do not mix or dilute Lantus® with other insulins. Do not use in an insulin pump or intravenously.
• Never share pens or needles.

Missed dose: Follow prescriber guidance. If a dose is missed, contact your care team for advice. Do not double doses without direction. Monitor glucose more often if timing shifts.

• Storage: You can store unopened pens in a refrigerator at 2–8 °C. Do not freeze. Keep away from heat and light.
• In use: You may keep an in-use pen at room temperature (below 30 °C) for up to 28 days. Keep the cap on when not in use.
• Travel: You can carry pens in your hand luggage. Use a small insulated pouch with a cold pack barrier; avoid direct ice contact. Keep a backup pen and extra needles. Pack a copy of your prescription.

Benefits and Savings

Lantus® offers steady basal coverage for 24 hours in most patients. Once-daily dosing supports simpler routines. The smooth action helps reduce nighttime lows compared with older NPH insulin for some patients. It fits many regimens, including basal-only for type 2 diabetes or basal-bolus plans with rapid-acting insulin.

Ordering from YouDrugstore is simple and discreet. Many US patients see 60–80% savings compared with typical US prices. Savings can be meaningful for those paying without insurance. Multi-pen packs often reduce the per-month Lantus Solostar Pens cost.

Side Effects and Safety

All insulins can cause low blood sugar and other effects. Learn common and serious reactions, and contact your prescriber for individualized advice.

• Common: hypoglycemia (shakiness, sweating, fast heartbeat), injection site redness or swelling, weight gain, mild edema, and lipodystrophy at injection sites.
• Less common: itching, rash, or allergic-type reactions.
• Serious: severe hypoglycemia, severe allergic reaction, and hypokalemia. Seek urgent care for severe symptoms such as confusion, loss of consciousness, or breathing trouble.

Not for diabetic ketoacidosis. Confirm you have the right insulin and dose before each injection. Alcohol, missed meals, intense activity, kidney or liver issues, and drug interactions can increase hypoglycemia risk. Keep fast-acting glucose available and wear medical identification.

Onset Time

Lantus® generally begins working about 1–2 hours after injection. It has a flat, peakless profile in many users and lasts up to 24 hours or longer. Some patients need twice-daily dosing if duration is shorter. Your clinician will tailor timing to your glucose pattern.

Compare With Alternatives

Toujeo (insulin glargine U-300) is a more concentrated glargine with a longer, flatter profile and smaller injection volume. It can help reduce nocturnal hypoglycemia in some cases, but dose conversions differ. Tresiba (insulin degludec) offers ultra-long action with flexible dosing windows. Levemir (insulin detemir) has a dose-dependent duration and may require twice-daily dosing. Biosimilar or follow-on glargine products (such as Basaglar or Semglee) provide alternatives to Lantus® in some regions.

For mealtime coverage, rapid-acting analogs such as the Humalog® Kwikpen are often paired with a basal insulin. Intermediate-acting human insulin, like the Novolin® Ge Nph Penfill Cartridge or regular insulin such as the Novolin® Ge Toronto Vial, may be options when cost or clinical needs guide selection. Compare features with your prescriber to choose the right plan.

Combination Therapy

Lantus® SoloStar is commonly used with metformin and other oral agents for type 2 diabetes. Many patients use a basal-bolus regimen, combining Lantus® for background coverage with a rapid-acting insulin at meals. Some clinicians pair basal insulin with a GLP-1 receptor agonist to improve control and weight outcomes in adults with type 2 diabetes.

Patient Suitability and Cost-Saving Tips

Lantus® is suitable for adults with type 1 or type 2 diabetes who need long-acting basal insulin, and for children with type 1 diabetes as directed by their clinician. It should not be used for diabetic ketoacidosis. Discuss use during pregnancy or breastfeeding with your healthcare provider.
