Needle Tips for Lantus SoloStar Insulin Pens
The recommended needle tip for Lantus SoloStar insulin pens is a 4-mm pen needle inserted at a 90-degree angle, which is suitable for all adults regardless of age, sex, ethnicity, or BMI. 1
Needle Selection Guidelines
Recommended Needle Length
- 4-mm pen needles are the safest and most effective option for all patients using Lantus SoloStar pens 1
- These shorter needles:
- Minimize risk of intramuscular injections
- Reduce pain during injection
- Provide accurate dosing
- Are reported by patients to be less painful than longer needles 1
Special Populations
- Very young children (≤6 years old) and very thin adults: Should use the 4-mm needle with a lifted skinfold technique 1
- Obese patients: The 4-mm needle is still safe and effective, though a 5-mm needle may also be acceptable 1
Proper Injection Technique
Needle Insertion
- Insert the 4-mm needle perpendicularly (90° angle) to the skin surface 1
- For very thin patients: Use a lifted skinfold technique while maintaining the 90° angle 1
- After insertion, press the thumb button along the axis of the pen, not at an angle 1
Injection Process
- Prime the pen before injection to ensure free flow (follow manufacturer's instructions) 1
- Insert the needle fully before touching the thumb button 1
- Press the button completely and hold for a count of 10 before removing the needle 1
- Remove the needle without pressing the area 2
Important Safety Considerations
Single-Use Only
- Pen needles should be used only once and then properly disposed 1
- Needles are no longer sterile after use 1
- Reusing needles is associated with:
- Lipohypertrophy development
- Injection pain
- Bleeding 1
Needle Handling
- Do not leave needles attached to the pen after use 1
- Remove and dispose of needles immediately to prevent:
- Air or contaminants entering the cartridge
- Medication leakage
- Dose inaccuracy 1
Pen-Specific Considerations
- SoloStar pens have been shown to require lower injection force compared to other insulin pens, which may benefit patients with dexterity issues 3
- The SoloStar pen has demonstrated high dosing accuracy in clinical settings 4, 5
Common Pitfalls to Avoid
- Never share insulin pens between patients, even with new needles 1
- Avoid injecting into areas of lipohypertrophy, inflammation, edema, or infection 1
- Do not push the thumb button before the needle is fully inserted 1
- Avoid storing insulin in cold temperatures before injection as this can cause more pain 1
By following these guidelines for needle selection and proper injection technique with Lantus SoloStar insulin pens, patients can achieve optimal insulin delivery while minimizing pain and complications.
