Abilify, or aripiprazole, is an antipsychotic drug, typically prescribed to those suffering from schizophrenia. It has also been approved in the treatment of manic conditions, depression and bipolar I disorder. Likewise, autistic patients with irritability issues or tics can also benefit from Abilify. A daily dosage journal is important for patients taking Abilify. This allows them to monitor their intake, and adjust the dosage needed to prevent unwanted side effects. The most common side effects are weight gain, insomnia and some headaches.
