Most medical professionals and experts insist that lancets (the little needles in glucose testing kits) should be changed after each finger poke. That is what the Food and Drug Administration (FDA) literature says, and what those teaching diabetes care are supposed to emphasize.

When should I change my lancets?

Although it is a good idea to change it about once a day, many diabetics do not find an issue with changing it once every 1-2 weeks. Every diabetic is different, it just depends on how much the prick bothers you! As long as no one else is using your pricker, there is no need to change it each and every time.

How often can you use the same lancet?

Officially, all lancets are single use. Though reusing is a fact of life, and many people do it. People often do it to save money, or if they are running out and won't be able to buy more. Just like everything else, you need to be smart and do it in moderation.
