Message: <blockquote data-quote="EllieM" data-source="post: 2408510" data-attributes="member: 372717">I am posting this because I have now had the mechanism of a humalog insulin pen (so Eli Lilley I guess) die after just 3 months. My previous pen died in a similar way, but I just thought that it was normal for old pens to break.But, I really don't remember this happening in the past - I've had new pens due to losing them or getting a new kind of insulin, and I'm guessing one or two must have broken, but I really don't remember it.  The defect is that the pen doesn't always click properly when I turn the dial, and then gives me a lot of resistance when I try to press the plunger and doesn't deliver any insulin. (I can't even get it primed.)So, is this a known issue with faulty pens?  I'm just really suspicious that the new pen is from the same pharmacy and is the same colour (same batch?) as the old pen, and has died so quickly.Luckily I always keep some old disposable syringes in reserve....</blockquote>
