There is a study out, giving children DEX instead of cortef, and they found in the study that the DEX is more potent than the mfg states. I read the study and it was very interesting. The site for the study is somewhere in the message board in the last couple of weeks. So what I am saying is she might be getting more than enought DEX compared to the Cortef, I will find the name of the Dr. that did the study.
