Hi I am new here and hope someone can give me some advice. I have had diabetes for 17 years and have been on insulin for around 12 of those years. I have had two or three pens for the quick acting insulin and the present pen I use must be five or more years old at least. I was told that glucose meters should be replaced every three years but I wondered if the same thing applied to insulin pens. I've tried finding information on how long an insulin pen lasts before it should be replaced but I haven't found anything yet. I use the pen three times a day and wonder sometimes if it is giving the right dose. My local area health authority have decided to make everyone use a certain meter, because the test strips are cheaper and they think they will be saving money but there are so many errors with this new meter that I am using twice as many test strips as I was before which defeats the object of the change. The meter is a Glucolab and I wonder if anyone has also had trouble with it.
