How to replace the insulin pen cartridge
There are special insulin cartridges for insulin injection, which should not be mixed, so as to avoid inaccurate insulin dosage and affecting blood glucose changes. The method to replace the cartridge is:
1. Remove the needle
2. Take out the cartridge
3. Loading new cartridges
4. Install a new needle
When replacing the cartridge, be sure to check whether the cartridge is intact, whether it is the insulin dosage form you use, whether the insulin liquid has precipitation or crystallization, and the expiration date of the insulin, and install it after confirmation. Be sure to check the change of blood glucose when injecting insulin, and do not change the dosage and dosage form without permission.
