I was looking here to see if anyone had actually had a problem from re-using needles, and I don't see any report of this kind. All the discussion seems to be about terrible things that MIGHT happen. I admit I am a skeptic on these things, and it goes back to lancets. I read all the stuff about how you had to change the lancet every time. And then in "Type 2 Diabetes: An Essential Guide for the Newly Diagnosed," which has a lot of impressive praise, I read: "The instructions to your meter will tell you to use a fresh lancet every time you test, but many people use the same lancet for days, weeks, or even months without changing. It seems that people usually build up immunity to germs on their own skin, and infections from used lancets are rare." I took this to heart, and it worked for me. I bought a box of 100 lancets 12 years ago, and I bet over 90 are still in there. I used one lancet for two years with no problem. I finally changed it because I had some time on my hands one day, and nothing else to do. I suspected the same overstatement of the need to change needles would be true when I switched to insulin, and pressed my doctor hard on this issue. He finally said I could use a needle "until it hurts." (Apparently the silicon coating eventually wears off.) So I´ve been experimenting, using needles several times. So far so good. One always has to keep in mind the number one rule of the medical profession: CYA ("Cover Your Ass.") I was hoping for more empirical information and candor on this forum, and less simple passing on of the conventional wisdom. Anyone have any real information?.
