Lantus® SoloStar Pens for Diabetes

Lantus® SoloStar is a prefilled insulin glargine U-100 pen used as a long-acting basal insulin. It supports steady blood sugar control in type 1 and type 2 diabetes. You can order from Canada with US delivery, which helps many patients save even without insurance.

CanadianInsulin connects patients with licensed Canadian pharmacies. Prescriptions are verified with your clinic before dispensing.

What Lantus® Is and How It Works

Lantus is insulin glargine 100 units/mL. It is a long-acting insulin designed to provide a smooth, 24-hour basal effect. The formulation forms microprecipitates in the subcutaneous tissue. These release small amounts of insulin over time for stable coverage.

It does not replace mealtime insulin in type 1 diabetes. In type 2 diabetes, it is used as basal therapy alone or with other agents. Lantus has no pronounced peak when used as directed. This can reduce overnight swings when compared with NPH insulin.

We ship Lantus SoloStar pens from Canada to the US. This page explains usage, safety, and ways to access Canadian pricing with US shipping.

Who Lantus® Is For

Lantus is indicated for adults with type 1 or type 2 diabetes. It is also indicated for pediatric patients with type 1 diabetes when age and label criteria are met. It is not approved for diabetic ketoacidosis. Rapid-acting insulin is needed for that condition under clinical care.

Avoid Lantus if you are allergic to insulin glargine or any component. Use caution if you have frequent hypoglycemia, low potassium, or significant liver or kidney disease. Discuss pregnancy and breastfeeding plans with your clinician before use.

Dosage and Usage

Use Lantus once daily at the same time each day. Inject subcutaneously into the abdomen, thigh, or upper arm. Rotate sites to reduce lipodystrophy.

For type 2 diabetes, a common starting dose is 10 units once daily or about 0.2 units/kg once daily. Dose adjustments are usually made every few days based on fasting glucose goals set with your clinician.

For type 1 diabetes, total daily insulin is divided into basal and bolus components. The basal portion is often about one third to one half of the total daily insulin. Your clinician will individualize your starting dose and titration plan.

Do not dilute or mix Lantus with other insulins. Do not administer intravenously or via an insulin pump. Refer to the official label for full dosing instructions.

Strengths and Forms

The SoloStar pen is prefilled with 3 mL of insulin glargine at 100 units/mL. The pen delivers 1 unit increments and is suitable for most adult dosing needs. Availability may vary by region and pharmacy.

Lantus also comes in other presentations. Some patients use a vial and syringe or reusable pens with cartridges. If you need a different format, see Lantus® Cartridges or the Lantus® Vial.

Missed Dose and Timing

If you miss a dose, take it as soon as you remember the same day. If it is close to the next dose, skip the missed dose. Do not double your next dose. Monitor blood glucose closely and follow your clinician’s guidance.

Try to take Lantus at the same time every day. Set phone reminders or use a calendar to support consistency.

Storage and Travel Basics

Unopened pens should be refrigerated and protected from freezing. Do not use if the product has been frozen. Once in use, most SoloStar pens can be kept at room temperature for a limited period as stated in the official label. Keep away from direct heat and light. Discard pens that are past the in-use time, even if insulin remains.

When traveling, carry insulin in your hand luggage. Use a protective case. For longer trips, use cooling packs and avoid direct contact with ice. We use cold-chain handling when needed to help protect medication quality in transit. For more details, see our guide on Lantus® Storage.

Pen Handling and Sharps Disposal

Inspect the pen before use. The insulin should be clear and colorless, with no particles. Attach a new needle for each injection. Prime the pen per label, commonly 2 units, until you see insulin at the tip. Dial your dose and inject at the recommended angle into subcutaneous tissue.

Keep the needle under the skin for several seconds after the plunger reaches zero to ensure full dose delivery. Rotate sites with each injection. Do not share pens, even with new needles.

Dispose of used needles in a sharps container. Follow local rules for sharps disposal. If you are new to pen devices, review our overview of Insulin Pens and this detailed article on the Lantus® Solostar Insulin Pen.

Benefits

Lantus provides steady 24-hour basal coverage for many patients. Once-daily dosing simplifies routines. The SoloStar pen is discreet and easy to carry. Pens allow accurate 1 unit titration and reduce the need for vials and syringes.

Compared with intermediate-acting NPH, Lantus has a smoother profile. This may reduce nocturnal lows when used appropriately. Results vary by individual.

Side Effects and Safety

• Hypoglycemia, including shakiness, sweating, hunger, or confusion
• Injection site redness, itching, or mild swelling
• Weight gain over time
• Edema (fluid retention)
• Lipodystrophy or skin thickening at injection sites

Serious reactions can occur. These include severe hypoglycemia, allergic reactions, and hypokalemia. Insulin may cause sodium retention and edema, especially with thiazolidinediones. Seek medical help if you have severe symptoms, difficulty breathing, widespread rash, or persistent low sugars.

When used with sulfonylureas, glinides, or prandial insulins, the risk of hypoglycemia increases. Monitor glucose more often during dose changes or illness.

Drug Interactions and Cautions

Many medicines can change insulin needs. Agents that may increase the glucose-lowering effect include ACE inhibitors, ARBs, salicylates, some SSRIs, and alcohol. Agents that may reduce the effect include corticosteroids, some diuretics, atypical antipsychotics, and certain contraceptives.

Beta-blockers can blunt the awareness of hypoglycemia symptoms such as tremor. Pioglitazone or rosiglitazone with insulin may increase edema and heart failure risk. Do not mix Lantus with other insulins or dilute it. Always check labels before injecting.

What to Expect Over Time

Fasting glucose often improves within days as doses are adjusted. Hemoglobin A1c changes are seen over weeks to months. Expect dose adjustments during illness, changes in activity, weight shifts, or new medications. Keep consistent meals, activity, and monitoring as advised.

Compare With Alternatives

Several long-acting basal insulins are available. Insulin glargine biosimilars may offer similar control. Basaglar® is an insulin glargine U-100 option. Insulin degludec offers an ultra-long profile with flexible dosing windows, such as Tresiba® Flextouch Pens. Your clinician can help choose among these based on your targets, lifestyle, and insurance.

Availability and Substitutions

Availability can vary. If a particular package size or pen is out of stock, your prescriber may recommend another presentation or a therapeutically appropriate alternative. Do not switch basal insulins without clinical guidance.

Patient Suitability and Cost Saving Tips

Good candidates are adults with type 2 diabetes needing basal support and patients with type 1 diabetes who require a basal component. Those with frequent unexplained lows, recurrent severe hypoglycemia, or insulin allergies may need a different plan. Pediatric suitability depends on age and label criteria.

To save on costs, consider multi-pack orders, which can extend the time between reorders. Align deliveries with your refill reminders so you avoid last-minute purchases. Ask your clinician about dose consolidation when appropriate, and use consistent injection technique to avoid waste.

Questions to Ask Your Clinician

• What starting dose and titration schedule should I follow for Lantus?
• How should I coordinate Lantus with my mealtime insulin or oral agents?
• What fasting glucose target should I use when adjusting doses?
• How can I reduce hypoglycemia risk during exercise or illness?
• Which injection sites are best for me, and how often should I rotate?
• What supplies do I need for travel and how should I store my pens?
• When should I consider an alternative long-acting insulin?
