Lantus Solostar Pens contain insulin glargine 100 units/mL in a prefilled disposable pen for subcutaneous injection. Lantus Solostar Pens can be bought online, with the strength, quantity, and device format matched to the directions from your diabetes care team. The 3 mL pen format is used for basal insulin therapy and should be ordered with the correct pen count and compatible needle needs in mind.
Lantus Solostar Pen Price, Strength, and Quantity
The Lantus Solostar pen price depends on the quantity chosen, the pack configuration, and whether the order is for a single pen or a multi-pen carton. Lantus SoloStar is supplied as a 100 units/mL insulin glargine pen. Each 3 mL pen contains 300 units, while a box of 5 pens contains 15 mL and 1,500 units total.
Total units matter when comparing the Lantus Solostar Pens cost with another insulin format. A lower total price may reflect fewer pens, fewer milliliters, or a different device. Compare the active ingredient, strength, device type, number of pens, and total supply before judging value.
Pen needles may be separate from the insulin pen. Many disposable insulin pens require compatible single-use needles, and needle size should follow the pen instructions or clinician direction. Do not assume needles are included unless the order details say so.
| Ordering detail | Why it matters |
|---|---|
| Lantus Solostar 100 units/mL | Confirms the insulin concentration for this pen format. |
| 3 mL prefilled pen | Each pen contains 300 units of insulin glargine. |
| Box of 5 pens | A carton contains 15 mL and 1,500 units total. |
| Disposable pen | The pen is discarded after use or after the in-use time limit. |
| Pen needles | Compatible needles may need to be selected separately. |
Why it matters: Five pens are not five doses; dose timing and amount must come from individualized treatment directions.
How to Order Lantus Solostar Pens Online
To order Lantus Solostar Pens online, choose the 100 units/mL SoloStar pen format and the quantity that matches the intended supply. The product name, active ingredient, concentration, and device should align with the treatment instructions you already follow. If the directions name SoloStar, do not substitute a vial, cartridge, or different pen format without clinical guidance.
US delivery from Canada may include temperature-sensitive handling steps for insulin products. Because insulin is sensitive to heat and freezing, packaging and route details should be read carefully during checkout. The service wording for insulin handling may include prompt, express, cold-chain shipping, but it should not be used as a reason to leave insulin exposed after arrival.
Quick tip: Match Lantus, insulin glargine, SoloStar, 100 units/mL, and the pen count before completing checkout.
What Lantus Solostar Insulin Pens Are Used For
Lantus SoloStar is a long-acting basal insulin used to improve blood sugar control in people with diabetes mellitus. Basal insulin provides background insulin coverage between meals and overnight. It is not a rapid-acting mealtime insulin and is not used to treat diabetic ketoacidosis.
People with type 1 diabetes usually need basal insulin along with mealtime insulin. Some people with type 2 diabetes use basal insulin alone or with other glucose-lowering medicines. The overall plan depends on glucose patterns, meals, activity, other medicines, kidney function, and low blood sugar risk.
Lantus insulin glargine is designed for a gradual, long-acting effect rather than meal-by-meal glucose correction. The pen format helps deliver dialed doses from a prefilled device, but it does not determine the correct dose. Dose amount, timing, missed-dose instructions, and blood glucose targets need individualized direction.
Device Format: Prefilled Pen, Not a Refill or Cartridge
The Lantus Solostar insulin pen is a prefilled disposable pen injector. It is not a Lantus Solostar pen refill, a reusable pen body, or a Lantus SoloStar cartridge. The entire pen is discarded when it is empty or when the in-use period has expired.
Lantus is the medicine name, and SoloStar identifies the pen device. The pen contains insulin glargine 100 units/mL and is intended for injection under the skin. Do not transfer insulin from the pen into another container or device unless official instructions and a qualified clinician specifically direct that process.
Each pen should be used by one person only, even when a new needle is attached. Sharing an insulin pen can transmit blood-borne infections. Use a new needle for each injection, remove the needle after use as directed, and place used needles in an appropriate sharps container.
- Active ingredient: insulin glargine.
- Strength: 100 units/mL.
- Format: 3 mL prefilled disposable pen.
- Route: subcutaneous injection, meaning injection under the skin.
- Class: long-acting basal insulin.
Storage, Handling, and Travel
Unopened SoloStar pens are usually stored in a refrigerator at 2°C to 8°C, or 36°F to 46°F. Keep insulin away from the freezer compartment, direct heat, and bright light. Do not use a pen that has been frozen, overheated, or kept outside the storage range described in the package information.
After first use, the pen is typically kept at room temperature and discarded after 28 days, even if insulin remains. The exact storage range and discard timing should be followed from the manufacturer leaflet supplied with the medication. Writing the first-use date on the carton or a medication log can help prevent accidental use past the in-use limit.
Inspect the solution before injection. Lantus should look clear and colorless, without particles, cloudiness, or discoloration. If the insulin looks unusual, do not use that pen until a pharmacist or clinician advises what to do.
For travel, keep insulin and injection supplies in carry-on storage where temperatures stay more stable. Avoid checked luggage, parked cars, freezer packs touching the pen directly, and unprotected bags in extreme weather. Browse the insulin medication category if you need to distinguish pen, vial, and other insulin formats before planning supply needs.
Side Effects, Warnings, and Monitoring
The most important risk with any insulin is hypoglycemia, or low blood sugar. Symptoms may include shakiness, sweating, fast heartbeat, hunger, headache, confusion, or weakness. Severe low blood sugar can cause seizure, loss of consciousness, injury, or death if not treated quickly.
Common or clinically important effects may include injection-site reactions, itching, rash, swelling, weight gain, fluid retention, and changes in fatty tissue under the skin. Rotating injection areas as instructed can reduce thickened skin, dents, or lumps that may affect insulin absorption. Contact a healthcare professional if injection sites become painful, infected, or difficult to use.
Lantus should not be used during an episode of low blood sugar or by anyone with a known allergy to insulin glargine or any listed ingredient. Seek urgent medical help for signs of a serious allergic reaction, such as swelling of the face or throat, trouble breathing, severe dizziness, or widespread hives.
Insulin can also lower potassium levels in the blood. Low potassium may cause muscle weakness, cramps, or heart rhythm changes and can be serious in people taking certain medicines. Monitoring may include blood glucose readings, A1C testing, injection-site assessment, kidney-related review when clinically relevant, and attention to changing insulin needs during illness or medication changes.
| Safety issue | Practical action |
|---|---|
| Low blood sugar | Know symptoms and follow the treatment plan given by your care team. |
| Allergic reaction | Get urgent help for breathing trouble, facial swelling, or widespread hives. |
| Skin changes | Rotate injection areas as directed to support consistent absorption. |
| Low potassium | Report weakness, cramps, or heart rhythm symptoms promptly. |
| Pen sharing | Never share a pen, even if the needle has been changed. |
Interactions and Blood Sugar Changes
Many medicines can raise or lower blood sugar and may change insulin requirements. Examples include other diabetes medicines, corticosteroids, diuretics, some blood pressure medicines, and certain mental health medicines. Beta blockers may make typical warning signs of low blood sugar harder to notice.
Alcohol, missed meals, illness, changes in exercise, stress, and weight changes can also affect readings. Blood glucose should be monitored as directed, especially when another medicine starts or stops. Do not change the dose, timing, or injection frequency based only on online product information.
People using other diabetes medications should understand how each medicine affects glucose and low blood sugar risk. A basal insulin plan may look different from a plan using rapid-acting insulin, non-insulin injectables, or oral medicines. The diabetes condition section can help place insulin therapy in the broader treatment context.
Comparing Basal Insulin and Related Diabetes Products
Lantus Solostar basal insulin is different from rapid-acting insulin, mixed insulin, and non-insulin diabetes medicines. Rapid-acting insulin is usually tied to meals or corrections, while basal insulin provides background coverage. GLP-1 medicines and other non-insulin treatments have different active ingredients, dosing logic, side effect profiles, and monitoring needs.
If another insulin glargine format is being considered, compare the exact device and strength. A vial, cartridge, or different pen may require different supplies and instructions. The long-acting insulin category is useful for browsing basal insulin formats, but any switch should be clinically directed.
Customers comparing the Lantus Solostar pen price without insurance should focus on the total insulin supplied, not only the carton name. Cash-pay comparisons work best when the same active ingredient, concentration, device, and quantity are being compared. Separate needle costs and storage needs may also affect the practical total.
For broader treatment browsing, the diabetes product category groups diabetes supplies and medicines, while the diabetes articles category covers general education topics. Internal education content can support discussion with a clinician, but it should not replace individualized treatment instructions.
