I am on another kind of drug, so I can't give a straight answer.

From what I can get Aripiprazole is usually used as an add-on, meaning you are most likely be prescribed something else as well.

In my case, I am taking escitalopram (Lexapro, but I use generic brand) as the main treatment drug and quetiapine (Seroquel) as an add-on.

Aripiprazole and Quetiapine are both antipsychotics (tranquilizers), but different category. In my experience taking Quetiapine continuously makes me feel sluggish, absent minded, like getting sedated. Reducing the dosage helps. As I don't take it for too long, and I use low doses, I don't experience any long term side effects.

Escitalopram is used much longer in my case. It's an antidepressant, so it is the main drug. Been taking it for almost 3 years now. Most common side effect is weight gain. While it didn't happen to me, I did catch myself craving sweet foods and drinks more than what I used to be. Must conciously make good dietary choices. Other than that I have no complaints.
