I read the paper and contacted the Dr. I was thinking he was in California. It was very interesting. Anyway his findings were that children could take DEX but you need to be very careful because DEX is much more potent than cortef and more potent even than the manufacturer states, accordingly kids need a very small dose of DEX. If you were to switch to DEX I would read his study and contact him for dosing information. I did not switch my kids, the reason they found kids did better on the DEX was due to better compliance, my kids are still little so compliance was not really and issue for us.
