Risks of multiple use

This symbol on the pen needle box indicates that they are single-use products.

Multiple use of the pen needle can lead to the following risks:

  • The pen needle is somewhat blunted after single use, the lubricant film can show signs of wear and the tip of the pen needle can be deformed:
    • Injections become more painful.
    • This can lead to small injuries or bruising.

 

  • The pen needle is no longer sterile after initial use:
    • Re-use is not hygienic.
    • Increased risk of infections.

 

  • Insulin can crystallise in the pen needle:
    • The pen needle may become clogged and a safe insulin injection is therefore no longer guaranteed.
    • This can lead to dosage errors and unexpectedly high blood glucose levels.

 

  • Presence or increase in size of air bubbles in the cartridge:
    • Insulin may drip out of pen needle (during storage).
    • Insulin dose becomes inaccurate.
