Abilify worked wonders for us. Both our neurologist and LLMD recommended it and we started it when we were at a really low point of behavioral stuff. We think this bahavior was due to herxing with Lyme and Bart treatment. We started out low and we saw results pretty quickly. This is the first behavioral type drug that has done anything for us. Of course every kid is different on what will work for them so it may not work for you.
Aidan is 50-55 lbs. IN the spring we started with 1 mg and moved up to 2 mg (minimum treatment dose for his weight) in a week or two. I saw results on the 1 mg and pretty quickly (a couple of days). I guess the average dose for Aidan's weight is 4-6 mg and we started seeing some behaviors again a month ago, so we moved him up to 3 mg and again saw results but it took more like a week. We are about to go on to 4 mg (actually 3.75 mg to save money - see below). I think it would be typical to take a week to see results but ask your doctor. It has helped with impulsive behavior, adhd, concentration, etc, He seems to be performing better at school and able to communicate better sinc being on it,
It is very expensive. (It is not generic yet and I had heard next year but when I search when online I think it won't be until 2015.) A while back I saw on the abilify website that they had a program where they would help you with your copay for 18 months so you might want to research that. It is for new prescriber so since Aidan had been on it for a few months we were not eligible for it. I save some money by getting it mail order through our prescription mail order and by buying larger size tablets and spliting them.
Also I think it is important to check glucose levels when on it, hopefully your prescribing doctor would be up on this.
