I have a 10-year-old son and a 7-year-old daughter, both with NC CAH. They are both on dexamethasone elixir in the AM only (1ml and 1.4ml respectively/ 0.5MG/5ML EMOR-whatever that means...).  They were on a dexamethasone pill that I broke in half when we were with a different endo. They ended up being oversupressed. Breaking a pill is never exact. The elixir (liquid) dosing is much more exact in a syringe.
