At Jaxson's Endo appointment 2 weeks ago we were given samples of the Humalog Kwikpen to start using. I kept one and sent the other off to be used at school. I seem to be having nothing but problems with our pen. With every injection it seems as if I've given him nothing and his bg continues to rise. I thought perhaps the initial pen needles were too small. We switched back to dosing him with syringes and his bg fell in line. So we went to the next gauge pen needle thinking this was the problem, but again, his bg is on the rise. In the meantime, the school nurse is getting great numbers with her pen. My only other solution is to toss out the insulin pen and start a new one. Anyone else ever have issues like this?
