Toujeo DoubleStar/SoloStar Prefilled Pen Price and Options
Use the displayed product fields to compare the current listed price with the selected pen presentation and quantity. For insulin pens, the total shown on a listing can reflect the number of pens, the volume in each pen, and the concentration rather than a single daily dose.
Toujeo is a U-300 insulin glargine product, meaning it contains 300 units of insulin per mL. A Toujeo prefilled pen may hold a different total number of units depending on whether the listing is for SoloStar, DoubleStar, or a similar high-capacity presentation.
- Concentration: Confirm 300 units/mL appears on the selected product.
- Device type: Match SoloStar, DoubleStar, or Max SoloStar wording to the prescription.
- Pack count: Check how many pens are included before comparing totals.
- Total units: Review pen volume and concentration together.
- Needle needs: Pen needles are usually selected separately.
Why it matters: A larger pen can contain more insulin without changing the 300 units/mL concentration.
When comparing the Toujeo SoloStar price, avoid assuming that all pen listings contain the same total insulin. If paying cash, compare the checkout total with the selected quantity rather than a single-pen estimate.
For Toujeo cost without insurance questions, focus on device type, pack count, and current availability. The displayed total may change when a different presentation is selected.
How to Buy Toujeo DoubleStar/SoloStar Prefilled Pen Online
Start by choosing the pen presentation that matches the written directions from your prescriber. Keep the product name, concentration, dose instructions, and prescriber contact information available in case details need to be checked before the order can move forward.
- Select the pen: Choose the listed device and quantity.
- Confirm the strength: Check for 300 units/mL.
- Provide order details: Enter requested prescription information accurately.
- Review handling needs: Insulin may require temperature-controlled packing.
Prescription details may be reviewed or verified when needed, and supporting documents may be requested for some orders. This helps ensure the selected Toujeo insulin pen aligns with the product your clinician intended.
Quick tip: If your prescription says DoubleStar or Max SoloStar, do not substitute SoloStar unless your clinician confirms the change.
Pen Presentation and Strength Details
The Toujeo insulin glargine pen is a long-acting insulin device used for once-daily basal insulin delivery when prescribed. The key product detail is the U-300 concentration, which is more concentrated than U-100 insulin glargine products.
| Presentation | What to check | Why it matters |
|---|---|---|
| SoloStar | Typically a 1.5 mL U-300 pen containing 450 units total | Often selected when the prescribed dose fits standard pen increments |
| DoubleStar | Typically a 3 mL U-300 pen containing 900 units total | Designed for larger-capacity use and usually dials in 2-unit increments |
| Max SoloStar | A high-capacity U-300 pen used in some markets | May reduce pen changes for patients prescribed higher daily amounts |
| Pen needles | Needle length and gauge are selected separately | Fit, comfort, and technique should be confirmed before use |
Toujeo DoubleStar vs SoloStar is mainly a device-capacity and dose-increment question, not a different insulin ingredient question. Both are Toujeo 300 units/mL pen presentations, but the larger-capacity device can hold more total insulin and may dial differently.
Never draw insulin out of a Toujeo pen with a syringe. The pen is designed to deliver concentrated insulin through its dosing mechanism, and using a syringe can cause a serious dosing error.
If you are comparing needle options, the Insulin Pen Needles resource can help you prepare practical questions about length, gauge, and disposal.
What This Long-Acting Insulin Is Used For
Toujeo contains insulin glargine, a basal insulin (background insulin) used to help manage blood sugar in people with diabetes when a clinician prescribes it. It is not a mealtime insulin and is not intended for rapid correction of high blood sugar after food.
This medicine is given under the skin using the prefilled pen. It should not be used to treat diabetic ketoacidosis, a serious condition that requires urgent medical care and different treatment.
Customers comparing prescribed basal options can browse the Long Acting Insulin category, then return to this listing to match the exact pen and concentration.
Storage, Cold-Chain Handling and Travel
Insulin is temperature sensitive, so storage details matter before and after ordering. Unused pens are generally stored in a refrigerator at 2°C to 8°C and should not be frozen, placed next to a freezer element, or exposed to direct heat.
- Before use: Keep unopened pens refrigerated as directed.
- After first use: Follow the in-use period on the supplied label.
- Heat exposure: Do not use insulin left in a hot car.
- Freezing: Discard a pen if it has been frozen.
- Appearance: Do not use cloudy or colored solution.
Some Toujeo pen labels allow room-temperature storage for a limited period after first use, while regional product information may state different limits. Follow the carton and leaflet that arrive with your order.
Temperature-sensitive insulin may require prompt, express, cold-chain shipping so the package is handled as a refrigerated medicine. After arrival, inspect the package, move unopened pens to proper storage, and keep the leaflet for reference.
For travel planning, pack insulin where temperature is controlled and keep spare pen needles available. The Insulin Storage Temperature resource outlines practical storage points to discuss with your care team.
Safety Checks Before Using the Pen
The most important safety concern with any insulin is hypoglycemia (low blood sugar). Symptoms can include shakiness, sweating, fast heartbeat, hunger, confusion, headache, blurred vision, or unusual tiredness.
- Low glucose: Treat promptly using your clinician’s plan.
- Injection reactions: Redness, itching, or swelling can occur.
- Allergy signs: Rash, wheezing, or facial swelling needs urgent help.
- Low potassium: Weakness or abnormal heartbeat may be serious.
- Fluid retention: Swelling can worsen with some diabetes medicines.
- Pen sharing: Never share an insulin pen, even with a new needle.
Do not use Toujeo during an episode of low blood sugar or if you have had a serious allergic reaction to insulin glargine or a listed ingredient. Seek emergency care for severe hypoglycemia, trouble breathing, swelling of the face or throat, or loss of consciousness.
The pen should not be mixed with other insulin, diluted, used in an insulin pump, or injected into a vein. Use a new sterile needle for each injection and remove the needle after use to reduce leakage, blockage, and contamination risk.
Changes in insulin type, device, strength, injection timing, diet, activity level, illness, kidney function, or liver function can affect glucose control. Ask your clinician how often to check blood sugar when any of these factors changes.
Interactions and Monitoring
Many medicines can affect insulin needs or change how low blood sugar feels. Examples include other diabetes medicines, corticosteroids, diuretics, some blood pressure medicines, beta blockers, and alcohol.
- Beta blockers: May mask fast heartbeat from low glucose.
- Steroids: Can raise blood sugar in some patients.
- Alcohol: May increase low-glucose risk.
- Thiazolidinediones: Can worsen fluid retention with insulin.
- Illness: Fever or infection can change insulin needs.
Do not change dose, timing, or device based only on a product listing. Use the selected product details to confirm what you have been prescribed, then follow the monitoring plan set by your clinician.
Compare Related Basal Options
Toujeo, Lantus, Basaglar, Levemir, and Tresiba are all basal insulin options, but they are not identical products. Concentration, dosing device, duration profile, and substitution rules can differ.
| Option | Comparison point | Product-decision use |
|---|---|---|
| Lantus SoloStar Pens | Insulin glargine U-100 | Useful when comparing U-100 and U-300 glargine prescriptions |
| Tresiba FlexTouch Pens | Insulin degludec pen | Useful when comparing different long-acting insulin ingredients |
| Toujeo and Lantus Differences | Focused glargine comparison | Helps frame questions about concentration and device differences |
If your clinician writes for a Toujeo 300 units/mL pen, do not assume another basal insulin can replace it at the same dose. Matching the exact product, concentration, and device is part of safe ordering.

What is the difference between Toujeo DoubleStar and SoloStar?
Both devices contain Toujeo insulin glargine 300 units/mL, but they differ in capacity and dose dialing. SoloStar is typically a smaller-capacity pen, while DoubleStar holds more total insulin and commonly dials in 2-unit increments. The difference matters because the selected device should match the prescription and the way the dose is dialed. Do not switch between devices unless your clinician confirms the change.
What type of insulin is Toujeo SoloStar?
Toujeo SoloStar is a prefilled pen containing insulin glargine U-300. It is a long-acting basal insulin, which means it provides background insulin coverage rather than mealtime insulin action. It is used when prescribed to help manage blood sugar in diabetes. It should not be used for diabetic ketoacidosis, and it should not be mixed, diluted, or removed from the pen with a syringe.
How many units are in a Toujeo DoubleStar pen?
A Toujeo DoubleStar pen is typically a 3 mL U-300 pen, which equals 900 units of insulin in the full pen. That total is the amount contained in the device, not a single dose. The dose delivered depends on what is dialed according to the prescription. DoubleStar devices may dial differently than standard SoloStar pens, so training and device instructions matter.
What side effects should be monitored with Toujeo?
The main side effect to watch for is hypoglycemia, or low blood sugar. Symptoms may include shakiness, sweating, confusion, fast heartbeat, hunger, headache, or blurred vision. Injection-site redness or itching can occur. Serious allergy symptoms, severe low blood sugar, fainting, or breathing problems need urgent medical attention. Your clinician may also monitor potassium levels and overall glucose patterns.
What should I ask my clinician before using a different pen?
Ask whether the new pen has the same insulin ingredient, concentration, dose increments, and maximum single-injection amount as your current device. Confirm whether your dose needs to be adjusted, how often to monitor glucose during the change, and what symptoms should prompt medical help. Also ask for a demonstration if the new pen dials or primes differently.
Which pen needle size is used with Toujeo pens?
Toujeo pens are designed for use with compatible disposable pen needles, but needle length and gauge should be confirmed with your clinician or pharmacist. The right choice can depend on injection technique, site rotation, comfort, vision, and hand strength. Use a new sterile needle for each injection, remove it after use, and follow sharps-disposal instructions for your area.
