Please note: a valid prescription is required for all prescription medication.
Buy Lantus Solostar Pens online with a valid prescription and compare current listed pricing, available presentation details, and safety basics before checkout. Match the selected 100 units/mL prefilled pen to your order details, confirm whether the quantity is a single pen or a box, and review temperature-sensitive handling notes. If you are reviewing US delivery from Canada, check the displayed packaging and delivery information before placing your order.
Price, Forms, and Available Options
Use the listing to compare the current listed price with the exact presentation you need. The Lantus Solostar pen price may change with the selected quantity, pack count, and whether the item is listed as one pen or a multi-pen carton. Compare total mL, total units, and number of pens before comparing it with another insulin listing.
Lantus SoloStar is a prefilled disposable pen containing insulin glargine 100 units/mL. Each Lantus Solostar 3 mL pen contains 300 units of insulin, so a Lantus Solostar box of 5 pens contains five devices, 15 mL, and 1,500 units total. That total content is not the same as five doses, and it should not be used to calculate or change your daily amount.
When reviewing the Lantus Solostar Pens price, check whether pen needles are included or listed separately. Many insulin pens require compatible disposable needles, and the needle size should follow your clinician’s directions or the pen instructions. If more than one insulin glargine presentation appears on the site, choose the wording, strength, and device that match your prescription.
| Listing detail | What to compare |
|---|---|
| 100 units/mL concentration | Confirm the concentration matches the prescribed insulin. |
| 3 mL prefilled pen | Use the total contents to compare supply size. |
| Pack count | Check whether the listing is one pen or multiple pens. |
| Pen needles | Verify whether compatible needles are included or separate. |
| Storage needs | Plan for refrigerated handling before first use. |
How to Buy Lantus Solostar Pens Online
To order Lantus Solostar Pens online, select the presentation and quantity shown on the product page. Use the product name, concentration, and device type from your prescription when checking the listing. If your prescription specifies SoloStar, do not substitute a vial, cartridge, or different pen unless your prescriber changes the therapy.
A valid prescription is required for this insulin. Prescription details may be checked with your prescriber if the selected product, quantity, or directions need clarification. Supporting information may be requested for some orders, so keep current directions and prescriber contact details available during checkout.
Quick tip: Compare the product label, concentration, and device before entering checkout.
Because insulin is temperature sensitive, checkout details may include insulated packaging and cold-chain shipping where appropriate. Review the delivery information shown for the selected product rather than assuming a specific arrival date, package configuration, or temperature method.
Prescription, Pricing and Access
Cost comparison works best when the selected insulin, strength, device, and pack size match the prescribed item. A Lantus Solostar Pens cost estimate may not reflect the same total supply if another page lists a vial, cartridge, or different pack count. When comparing the pen price without insurance, check total units, total mL, and separate needle needs.
Cash-pay customers should focus on the displayed listing, selected quantity, and checkout fields before deciding whether the order path fits their situation. Cross-border access can depend on patient, product, and location rules, so use the page to confirm product details rather than to predict coverage or eligibility. The most useful comparison is the actual item you are selecting, not only the carton label.
Why it matters: A lower total unit count can make one listing look less expensive while providing less insulin.
Product Details That Affect Ordering
The Lantus Solostar insulin pen is a prefilled device for subcutaneous injection (injection under the skin). It contains Lantus insulin glargine 100 units/mL, a long-acting insulin analog. The pen is disposable, which means the device is discarded after the insulin is used or after the in-use time limit.
This presentation is not a Lantus Solostar pen refill, reusable pen body, or Lantus SoloStar cartridge. Customers sometimes search for cartridge wording because many insulin devices use replaceable cartridges, but SoloStar is a complete prefilled pen. Do not transfer insulin into another device unless official instructions and your clinician specifically direct that process.
Lantus is the medicine name, while SoloStar identifies the pen device. The Lantus Solostar pen injector is designed to deliver dialed doses from the prefilled pen, and each device should be used by one person only. The Insulin Pens And Storage resource compares pen terminology, needle basics, and routine handling language used on listings.
Before adding the item to checkout, confirm these details:
- Exact product name: Match Lantus, insulin glargine, and SoloStar wording.
- Concentration: Confirm 100 units/mL appears on the selected item.
- Device type: Choose a prefilled disposable pen if prescribed.
- Quantity: Compare pens, mL, and total units.
- Needle needs: Check whether pen needles are supplied separately.
What This Long Acting Insulin Is Used For
Lantus SoloStar is a long-acting basal insulin used to help control high blood sugar in people with diabetes mellitus. Basal insulin provides background insulin coverage between meals and overnight. It is not a rapid-acting insulin for meal spikes, and it is not used to treat diabetic ketoacidosis, a serious emergency involving high ketones and insulin deficiency.
People with type 1 diabetes usually need basal insulin plus mealtime insulin. Some people with type 2 diabetes use basal insulin alone or with other diabetes medicines. The right plan depends on glucose patterns, other medicines, hypoglycemia (low blood sugar) risk, and clinician assessment.
Use this product page to match the prescribed insulin, not to choose a new regimen. If you need to compare basal insulin listings by class, browse the Long Acting Insulin collection and then confirm any switch with your prescriber.
Storage, Handling and Travel Basics
Unopened SoloStar pens are usually stored in a refrigerator at 2°C to 8°C (36°F to 46°F) until use. Keep insulin away from the freezer compartment, direct heat, and bright light. Do not use a pen that has been frozen, overheated, or left outside the storage instructions.
After first use, the pen is typically kept at room temperature and discarded after 28 days, even if insulin remains. Check the patient leaflet or product packaging for the storage range that applies to your supply. Write the first-use date on the carton or a tracking note so the discard date is easy to follow.
Inspect the insulin before injection. It should look clear and colorless, without particles, cloudiness, or discoloration. If the solution looks different, do not use that pen until a pharmacist or clinician advises you what to do.
For travel, keep insulin with your injection supplies in a place where temperatures stay stable. Avoid checked luggage, parked cars, freezer packs touching the pen directly, and unprotected bags in hot or cold weather. Bring enough pen needles and a sharps-disposal plan if your clinician has instructed routine injections while away from home.
The Insulin Storage Temperature resource summarizes common temperature terms and handling mistakes that can affect insulin products.
Safety Checks Before Ordering
Review key safety points before adding any insulin glargine pen to checkout. Lantus should not be used during episodes of hypoglycemia or by anyone with a known allergy to insulin glargine or listed ingredients. Severe low blood sugar can cause confusion, seizure, loss of consciousness, or injury.
Common or important effects can include low blood sugar, injection-site reactions, itching, rash, fluid retention, weight gain, and changes in fatty tissue under the skin. Rotating injection areas as directed may reduce skin thickening, pits, or lumps. Seek urgent medical help for signs of a severe allergic reaction, such as swelling of the face or throat, trouble breathing, or widespread hives.
Never share a Lantus Solostar prefilled pen with another person, even if the needle is changed. Sharing pens can transmit blood-borne infections. Use a new needle for each injection and dispose of used needles in an appropriate sharps container.
| Safety issue | Why it matters |
|---|---|
| Low blood sugar | Symptoms can become severe and need quick treatment. |
| Allergic reaction | Swelling, wheezing, or hives need urgent care. |
| Low potassium | Weakness or heart rhythm changes need medical attention. |
| Skin changes | Repeated sites can affect insulin absorption. |
Interactions and Monitoring
Several medicines can raise or lower blood sugar, which may change insulin needs. Examples include other diabetes medicines, corticosteroids, diuretics, some blood pressure medicines, and certain mental health medicines. Beta blockers may also make typical warning signs of low blood sugar harder to notice.
Alcohol, illness, missed meals, changes in activity, and weight changes can affect glucose readings. Monitor blood sugar as directed, especially when another medicine starts or stops. Do not change the dose, timing, or frequency based on online product information.
Ask your clinician what to do if a dose is missed, if a pen is exposed to extreme temperatures, or if readings stay above or below your target range. If severe high blood sugar symptoms are a concern, Acute Hyperglycemia Warning Signs outlines symptoms that need prompt clinical attention.
Compare Related Options
Lantus Solostar basal insulin is not the same as GLP-1 medicines such as semaglutide, and it is not prescribed as a weight-loss medicine. It contains insulin glargine, a basal insulin analog. If your clinician is discussing alternatives, compare active ingredient, concentration, device type, action profile, and whether the medicine contains insulin.
Other Lantus presentations may appear on separate product pages. A prescription written for a vial should match Lantus Vial, while cartridge-specific directions should match Lantus Cartridges. These presentations are not interchangeable with a SoloStar pen unless the prescriber changes the device and directions.
Some combination pens include insulin plus another glucose-lowering medicine. Those products have different ingredients, dosing instructions, and safety profiles. Use comparisons to prepare questions for your clinician, not to substitute one insulin device for another.

How many units are in a SoloStar pen?
Each Lantus SoloStar pen contains 3 mL of solution at 100 units/mL, for 300 units total. That number is the total insulin in the device, not the number of injections or the amount a person should use. The number of days a pen lasts depends on the prescribed dose, priming needs, and the discard date after first use.
Is Lantus different from the SoloStar device?
Lantus is the brand name for insulin glargine, the long-acting insulin inside the device. SoloStar refers to the disposable prefilled pen used to inject that insulin. A vial, cartridge, and SoloStar pen may contain the same concentration but use different devices and instructions. Match the exact presentation on the label to the product your clinician prescribed.
How should unopened and in-use pens be stored?
Unopened pens are usually kept refrigerated and protected from freezing, heat, and light. After first use, SoloStar pens are typically kept at room temperature and discarded after 28 days, even if insulin remains. Storage ranges can vary by leaflet and region, so check the package insert supplied with your medication and do not use insulin that looks cloudy, colored, or contains particles.
What safety symptoms need prompt attention?
Severe low blood sugar, fainting, seizure, confusion, swelling of the face or throat, trouble breathing, or widespread hives need urgent medical help. Weakness, palpitations, or unusual heart rhythm symptoms may also need evaluation because insulin can contribute to low potassium. For routine concerns such as injection-site irritation or recurring glucose changes, contact your healthcare professional for individualized guidance.
What should I ask my clinician before using this pen?
Useful questions include when to inject it, what blood glucose range to monitor, what to do if a dose is missed, and how to handle illness, travel, or activity changes. Ask which pen needle size is appropriate and where to inject. Also confirm whether any current medicines, alcohol use, or recent hypoglycemia episodes affect your monitoring plan.
