I haven't posted here in a while. My son just turned 11. His dr. put him back on abilify. He is now taking 7.5 ml. each day. It seems to help somewhat, but he is still has occasional "fits of rage". He dr. wants to put him on an adhd medication called procentra. The pharmacy has not filled it yet. Since he had scary reactions to respidone and seroquil, I am really terrified to try this too. Since this is a stimulant, will this make his aggression worse? His dr. said that the effects of this medication is only 4 hours.
