An Introduction to Aripiprazole Side Effects

As with any medicine, there are possible side effects with aripiprazole (Abilify®). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate aripiprazole well. When side effects do occur, in most cases they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with aripiprazole. Your healthcare provider can discuss a more complete list of aripiprazole side effects with you.)
