Aripiprazole injection is used for the short-term treatment of agitation that occurs with certain mental/mood disorders (e.g., schizophrenia, bipolar disorder). It is given by injection when quick relief of your symptoms is needed or when you are unable to take the medication by mouth. When you are able to take medications by mouth, your doctor will change this medication to a form that can be taken by mouth. Aripiprazole is known as an antipsychotic drug (atypical type). It works by helping to restore the balance of certain natural chemicals in the brain (neurotransmitters). This medication can decrease hallucinations and improve your concentration. It helps you to think more clearly and positively about yourself, feel less nervous, and take a more active part in everyday life. Aripiprazole can treat severe mood swings and prevent or decrease how often mood swings occur.
