Anxiety in what sense? Abilify can cause restlessness--does that sound at all similar to the experience you're having--or if not, what kind of anxiety is it?
I have experienced restlessness with Abilify before, but that was about 9 years ago when I first started taking it. I don't experience it anymore, and I still take 30 mg of Abilify.
Perhaps it'd be best to discuss this anxiety with your prescriber? Maybe he or she could give you something to help with the anxiety or could give you a time frame as to when the anxiety might go away, if at all. Or, you could discuss switching to another drug with your prescriber as well.
Abilify, for me, has been very good at eliminating my depression. I don't know what the reason is that it was prescribed to you, but it would also help to know that, if you know.
