How often is it appropriate to change insulin needles?


Strictly speaking, insulin needles are disposable, generally require a needle to be replaced, and can not be reused after disinfection. If the patient's economic conditions permit, it is recommended to change the insulin needle once, at least 2-3 days. If the needle is not changed in time for some reason, a needle should not be used for more than 3 days.

In addition, check whether the needle is smooth before each subcutaneous injection, usually adjust the insulin dose 1-2 units, press the injection button, if the needle can appear a small amount of insulin overflow, indicating that the needle is smooth, if the exhaust, there is still no insulin overflow, to check the needle in time, if there is a discount in time to replace.
