We just came from our quarterly endocrinologist appointment. A few weeks ago, we stopped the pump after almost 4 years on bc of allergic reactions. We have since learned he was almost definitely reacting to the Novolog. So we also switched to Apidra at the same time as going back to MDI. There are now red dots--pimple size-- all over his belly and legs, in all the places he's had an injection for the past few weeks. NP said allergic reaction. Makes sense bc I've noticed a very delayed onset of action with the Apidra, and it's supposed to work more quickly, I understand. Assuming DS is allergic to both Novolog and Apidra, these are my questions: 1-has anyone else experienced anything like this? 2-what preservatives are in both insulins, and is the same preservative also in Humalog? 3-what if he is allergic to Humalog also?? Thank you!
