Lantus® SoloStar Pens for Diabetes

Lantus Solostar Pens are prefilled insulin pens used to help manage blood sugar in diabetes. This page explains how the pens work, who they suit, and how to use them safely. You will also find ways to compare options and estimate savings without insurance, with US delivery from Canada.

What Lantus Is and How It Works

Lantus® contains insulin glargine, a long-acting basal insulin. It releases slowly over 24 hours to support steady background insulin needs. That helps reduce fasting blood glucose and smooth daily fluctuations when used as prescribed.

These insulin glargine Solostar pens deliver fixed doses in small steps. The medicine forms microprecipitates after injection, allowing a gradual, consistent effect. Do not use to treat diabetic ketoacidosis. Always confirm your individualized plan with your prescriber.

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

Who It’s For

This treatment is used for adults with type 2 diabetes when basal insulin is indicated. It is also used for adults and some children with type 1 diabetes alongside mealtime insulin. People with a known hypersensitivity to insulin glargine or any excipient should avoid it.

Tell your clinician about kidney or liver problems, recent illness, or changes in activity. Discuss hypoglycaemia risk if you also use sulfonylureas or rapid-acting insulin. Learn more about the condition at Type 1 Diabetes and Type 2 Diabetes.

Dosage and Usage

Use once daily, at the same time each day, or as directed on your prescription. Inject into the fatty layer of the abdomen, thigh, or upper arm. Rotate injection sites to lower the chance of skin changes. This pen is for subcutaneous use only. Do not share pens or needles.

Prime the pen as the label instructs before each first use of a new pen. Attach a new, sterile needle for every injection and remove it after the dose. Do not mix or dilute this insulin with other products. If you have questions about injection technique, see our overview in How To Inject Mounjaro and follow your prescriber’s directions.

People switching from another basal may require careful monitoring during the change. Check blood glucose regularly, especially when diet, activity, or other medicines change. Lantus prefilled insulin pens deliver dose increments set by your prescriber; never alter your dose without clinical advice.

Strengths and Forms

Common presentations include:

• Lantus Solostar 100 units/mL pens, prefilled, 3 mL per pen
• Multi-pen cartons such as a 5-pen pack, availability can vary

Exact strengths and pack sizes may differ by market and supply. Your prescription will specify the format suited to your plan.

Missed Dose and Timing

If you miss a dose, take it as soon as you remember on the same day. If it is close to the next scheduled dose, skip the missed dose and resume your regular time. Do not double up. Monitor blood glucose and contact your healthcare professional for guidance on unusual readings or repeated missed doses.

Storage and Travel Basics

Keep unused pens in the refrigerator until first use. Do not freeze, and discard if frozen. After first use, store the in-use pen at room temperature as allowed by the official label and protect it from heat and direct light. Keep away from children and pets. Never use if the solution looks cloudy, colored, or contains particles.

When traveling, carry supplies in your hand luggage with a copy of your prescription. Use a protective case to avoid damage. Have backup needles and a second pen if advised. For supplementary supplies, visit our Diabetes Care section. Proper care helps keep Lantus insulin pens working as expected.

Pen Handling and Sharps Disposal

Wash your hands and check the label before each injection. Inspect the pen and cartridge window. Attach a new needle, prime as directed, dial your dose, and inject under the skin. Hold the button down for the full count before removing the needle from the skin.

Remove the needle after each injection. Place used needles in an FDA-cleared sharps container. Do not throw loose needles into household trash. Check local rules for disposal programs or drop-off sites. Suitable needles are available, such as BD Nano Pro, if compatible with your pen.

Benefits

This basal insulin offers once-daily dosing for most users. A steady release may help reduce overnight and between-meal highs. Prefilled pens are portable and can simplify daily routines. Clear dose steps and single-use needles support consistent technique. When combined with nutrition, activity, and monitoring, therapy can help keep targets within your plan.

Side Effects and Safety

• Low blood sugar: shakiness, sweating, confusion
• Injection site issues: redness, itching, or swelling
• Weight gain: may occur with improved control
• Edema: mild fluid retention in some people
• Allergic reactions: localized or systemic, rare but serious

Severe hypoglycaemia can be dangerous. Keep a source of fast-acting sugar available after discussing an emergency plan with your clinician. Beta blockers may mask warning signs. Seek urgent care for signs of a severe reaction, trouble breathing, or very low blood sugar that does not respond to treatment.

Drug Interactions and Cautions

Tell your prescriber about all medicines, vitamins, and herbal products. Sulfonylureas and other insulins can increase hypoglycaemia risk. Steroids, some diuretics, and certain antipsychotics may raise glucose. Alcohol can blunt awareness of lows. Thiazolidinediones may increase fluid retention when used with insulin. Always confirm changes with your healthcare professional.

What to Expect Over Time

Basal insulin usually works gradually. Many people notice steadier fasting readings after consistent use. Your prescriber may review logs to adjust your plan. Keep regular follow-ups and continue home monitoring. Maintain a routine around meals, activity, and injections to support stable results. Report unusual highs, lows, or injection site changes promptly.

Compare With Alternatives

Other long-acting options may suit some users. Insulin glargine biosimilar pens such as Basaglar Kwikpen offer a similar class. A concentrated glargine option like Toujeo Doublestar may be considered when appropriate. Your prescriber will select based on your history, targets, and dosing needs.

Availability and Substitutions

Supply can vary by pack size and manufacturer inventory. If your item is temporarily unavailable, your prescriber may recommend a similar basal alternative. You can also pay cash if you choose, or use your plan benefits when applicable. A valid prescription is required and verified before fulfilment.

Patient Suitability and Cost-Saving Tips

This therapy may be considered for adults with type 2 diabetes who need basal insulin and for people with type 1 diabetes alongside bolus insulin. It may not suit those with recurrent severe hypoglycaemia without close supervision or anyone with an allergy to components. Let your clinician know about any vision issues or dexterity limits that could affect pen use.

To manage costs, consider multi-month fills if your prescription allows. Set calendar reminders for refills to avoid gaps. Coordinate delivery ahead of travel. Compare pen pack sizes to match your monthly needs. If you pay out of pocket, review options that balance convenience and storage space.
