Dr. Wang Fangli reply Internal Medicine

If a syringe is used for personal use, it can generally be reused, but one must consider whether the needle has been contaminated during injection and how it is stored afterward.
Currently, insulin needles are becoming finer, which reduces the pain during injection.
However, reusing needles can lead to dullness and a decrease in the effectiveness of the lubricating coating on the needle surface, resulting in increased pain during injection.
Therefore, it is still not recommended to reuse needles; they should be disposed of after use.
Used syringes should ideally be stored in a metal container to prevent accidental needle sticks (in accordance with current waste classification).
Once full, it is advisable to take the container to a nearby clinic or hospital for proper disposal, as it is considered medical waste.

More Info

When it comes to diabetes management, particularly for those who use insulin injections, the question of whether needles can be reused is a common concern. The short answer is that while some people do reuse needles, it is generally not recommended due to safety and hygiene concerns.

Safety and Hygiene Concerns
1. Risk of Infection: Each time a needle is used, it can potentially introduce bacteria into the skin. Reusing needles increases the risk of skin infections, which can lead to more serious complications, especially for individuals with diabetes who may already have compromised immune systems.

2. Needle Dullness: Insulin needles are designed for single use. Repeated use can dull the needle, making it more painful to inject. A dull needle can also cause more tissue damage, leading to scar tissue formation, which can affect insulin absorption.

3. Dosage Accuracy: When a needle is reused, there is a risk that the dosage of insulin may not be accurate. Residual insulin left in the needle can mix with the new dose, leading to either an overdose or underdose, both of which can have serious consequences for blood sugar control.

4. Needle Safety Devices: Many modern insulin pens and syringes come equipped with safety features that are designed to prevent needlestick injuries. Reusing needles can compromise these safety features, increasing the risk of accidental pricks.

Recommendations
1. Single Use: It is strongly recommended to use a new needle for each injection. This practice minimizes the risk of infection and ensures that the needle is sharp and effective for insulin delivery.

2. Proper Disposal: After using a needle, it should be disposed of in a proper sharps container. This not only protects you but also others who may come into contact with discarded needles.

3. Education: Patients should be educated on the importance of using new needles and the risks associated with reusing them. Healthcare providers can offer guidance on proper injection techniques and disposal methods.

4. Consult Healthcare Providers: If you have concerns about the cost or availability of needles, discuss this with your healthcare provider. They may be able to provide resources or assistance to ensure you have access to the supplies you need.

Conclusion
In summary, while some individuals may consider reusing needles to save costs or for convenience, the potential risks far outweigh the benefits. For optimal safety and health, it is best to use a new needle for each injection. If you have further questions or concerns about your diabetes management, including needle use, it is advisable to consult with your healthcare provider for personalized advice and support.
