My doctor gave me a sample of the new Levemir pen. It has a green plastic thing around the insulin holder. Anyway, I'm interested to know if anyone has had a problem with it leaking. Last night I thought it might have been leaking, and when my morning bg was high I sort of think that was it. Just curious if anyone has seen this leaking in that pen. This has been the first time a pen has ever leaked on me in 10 years.
