Lantus Solostar pre-filled pen releasing insulin when pressed on zero setting

Thanks Garry for the feedback. I use the BD Micro 8mm needles with the lantus solostar.

Anyway sanofi uk quality team asked for the pen to be sent to them to investigate.

I am on different pen now and so far I have not had low BGs so far. Still get drops on "0" dose so I do not understand, May be I was pressing down too hard and longer than 10 seconds. With low dose such as mine, 5 units and 4 units, an additional half unit or 1 unit would make a difference.

I do tend to take the pen out of the fridge 10 hours or more before I need to use it so that would not be the issue,

Will wait and see what sanofi say ... may be it is something else but accuracy of the doses is not good unless one needs big doses in which case it would be tiny percentage. For lose doses it is not good. The Novopen 3 demi with novofine 6mm needles does not leak at all on "0"

Sanofi UK have responded saying NO FAULT FOUND. The feedback from their manufacturing site stated that the returned sample was found to be working correctly and compliant with the specification and the concentration of the insulin was within the specification and no fault could be detected. Other influences related to the therapy and interactions with other medications should be considered"

I wrote back referring to the "continuous dispensing of insulin (leakage) after reaching zero dose on the solostar pen"? Meanwhile I went back to counting one to ten as 1, 2, 3, 4.... and not as 1000, 2000, 3000, 4000... Have also just gone through period of carb free meals to make sure the split between the BI and QA is at the optimum level.
