Product overview
Description
Key Features & Ingredients
- U-40 disposable insulin syringe, calibrated for insulin at a concentration of 40 units per mL - a distinct, less concentrated graduation standard from the more common U-100 syringe, and not interchangeable with it
- Remains in active use in specific markets and regions, including parts of South Asia, for administering U-40-concentration insulin formulations that are still prescribed in those settings
- Fine-gauge needle, commonly around 31G with a short needle length typical for this category, built into a medical-grade plastic barrel with clear unit markings calibrated to the U-40 scale
- Supplied sterile in individually sealed packaging, made from non-toxic, non-pyrogenic materials, and intended for single use only
Benefits
- Clear U-40 unit graduations are intended to support accurate dosing specifically for people prescribed U-40 concentration insulin - using the matching syringe type is essential, since a mismatched syringe/insulin pairing can cause a significant dosing error
- The fine needle gauge is intended to make self-injection more comfortable
- Sterile, individually sealed, non-toxic packaging is intended to help maintain hygiene and safety until the moment of use
- Remaining available as a dedicated U-40 option helps ensure that people still prescribed this insulin concentration have access to a correctly calibrated syringe
Who Can Use This Product
- Intended specifically for people who have been prescribed U-40 concentration insulin by a physician - a distinct group from the majority of insulin users, who are typically prescribed U-100 concentration insulin
- Suitable for adults and, under a physician's or caregiver's supervision, children who require U-40 insulin therapy
- Not intended for anyone using U-100 concentration insulin - using this syringe with U-100 insulin can result in a significant dosing error; confirm your insulin's concentration with your physician or pharmacist before use
How to Use
- Before use, confirm with your physician or pharmacist that your prescribed insulin is specifically U-40 concentration - do not use this syringe with any other concentration
- Wash your hands and clean the injection site as instructed by your physician or diabetes educator before drawing up the dose
- Draw the prescribed dose by aligning the plunger with the correct unit marking on the U-40 scale printed on the barrel, then inject as directed by your physician or diabetes educator
- Use each syringe only once and discard it immediately after use
Storage & Safety
- Store unused syringes in their original sealed packaging in a clean, dry place at room temperature, away from direct sunlight
- Single use only - do not reuse or share a syringe between individuals
- Precaution: never mix up syringe types - measuring U-100 insulin with this U-40 syringe delivers roughly 2.5 times the intended dose, risking severe hypoglycemia, while measuring U-40 insulin with a U-100 syringe delivers only around 40% of the intended dose, risking persistent hyperglycemia. Always match the syringe scale exactly to your prescribed insulin's concentration
- Dispose of used syringes properly in a sharps container, never in regular household trash
Frequently Asked Questions
Q: What does "U-40" mean on this syringe?
A: It means the syringe is calibrated so its markings correspond to insulin at a concentration of 40 units per mL - a distinct, less common concentration than the U-100 standard used by most modern insulin formulations.
Q: Can I use this syringe with U-100 insulin?
A: No. Using U-100 insulin measured with a U-40-scale syringe results in a substantial overdose - roughly 2.5 times the intended amount - which risks severe hypoglycemia. Always use a syringe that exactly matches your prescribed insulin's concentration.
Q: What happens if I use U-40 insulin with a U-100 syringe instead?
A: You would deliver only a fraction of the intended dose - roughly 40% of it - which risks persistent hyperglycemia. This is why the syringe type must always match the insulin concentration exactly.
Q: Is U-40 insulin still used anywhere?
A: Yes. While U-100 is the dominant concentration in most modern insulin formulations, U-40 concentration insulin remains in active use in specific markets and regions, including parts of South Asia.
Q: Can I reuse this syringe?
A: No, it is intended for single use only. Discard it immediately after each injection in a sharps container.
Q: Who should use this syringe?
A: Only people who have been prescribed U-40 concentration insulin by a physician - confirm the concentration on your insulin vial or pen label, or with your physician or pharmacist, before use.
