If you notice insulin surrounding the white fill port, it may be drops of insulin left by the syringe and needle during the cartridge fill process. To confirm, blot away the residual insulin with a soft, clean tissue and confirm no additional leakage is observed. If no additional insulin is seen to be leaking, continue with the load process.
Always inspect your cartridges for any visible damage prior to filling with insulin. If you suspect the cartridge may be damaged, do not use it.
If you see insulin leaking from other parts of your cartridge, or from the cartridge pigtail, you will need to discard the leaking cartridge, then fill a new cartridge with insulin.
When filling the cartridge with insulin, ensure that you do so with the syringe and need that are packaged with the cartridge. Never fill the cartridge while it is connected to the pump.
Ensure that you pay special attention to not overfilling cartridges. For t:slim X2 cartridges, the total amount of insulin in the cartridge should never exceed 300 units.
Always refer to the User Guide for important safety information and detailed step-by-step instructions on how to load a cartridge. Please consult the applicable user guide and refer to the table of contents.
