What Is Aristada Used For?

Aristada is a long-acting injectable medication used to treat schizophrenia in adults.

Schizophrenia is a mental illness estimated to occur in up to 0.64% of people in the United States. Schizophrenia can affect how people with the disease think, behave, and perceive reality. Symptoms may include:

  • Hallucinations
  • Delusions
  • Unusual, disorganized speech
  • Reduced emotional expression
  • Lack of motivation
  • Difficulty with social relationships

Antipsychotic medicines, like Aristada, can help control schizophrenia symptoms.

How to Take Aristada

Aristada is an intramuscular injection administered by a healthcare provider once every four, six, or eight weeks. If you've never taken aripiprazole (the active ingredient in Aristada), your healthcare provider will likely prescribe Abilify (oral aripiprazole) for up to two weeks before starting Aristada to evaluate your body's reaction.

The first time you receive Aristada, your healthcare provider may also choose to administer Aristada Initio (a different injectable form of aripiprazole) and one dose of Abilify (oral aripiprazole). Alternatively, your healthcare provider may tell you to take oral aripiprazole for up to three weeks after your first Aristada injection.


Your healthcare provider will store and administer your dose of Aristada.

How Long Does Aristada Take to Work?

Aristada levels take time to build up in your body. After receiving your first dose of Aristada, levels become therapeutic within four to six days. But it may take up to four months to see the full effect. Talk with your healthcare provider about what to expect.

What Are the Side Effects of Aristada?

This is not a complete list of side effects, and others may occur. A healthcare provider can advise you on side effects. If you experience other effects, contact your pharmacist or healthcare provider. You may report side effects to the Food and Drug Administration (FDA) at or 800-FDA-1088.

Dosage: How Much Aristada Should I Take?

The following modifications (changes) should be kept in mind when using Aristada:

Severe allergic reaction: Do not take Aristada if you have a known allergy to it or its ingredients. Ask your pharmacist or healthcare provider for a complete list of the ingredients if you're unsure.

Pregnancy: Babies exposed to antipsychotic medicines like Aristada during the third trimester are at risk of developing abnormal muscle movements or withdrawal symptoms after delivery. Babies may experience agitation, trouble feeding, muscle stiffness or weakness, difficulty breathing, tiredness, and tremor. Some babies may recover within hours without specific treatment, while others may need to be hospitalized. Let your healthcare provider know if you're pregnant or plan to become pregnant, and discuss the benefits and risks of taking Aristada during your pregnancy. If you become pregnant while receiving Aristada, talk with your healthcare provider about registering with the National Pregnancy Registry for Atypical Antipsychotics.

Breastfeeding: Aristada is present in breast milk, but there isn't enough information about the safety of Aristada in nursing babies. Talk with your healthcare provider if you plan to breastfeed. Discuss the benefits and risks of taking Aristada while nursing and the different ways to feed your baby.

Adults over 65: The safety and effectiveness of using Aristada in adults over 65 have not been determined. However, older adults with dementia-related psychosis treated with antipsychotic drugs like Aristada have an increased risk of dying.

Children: Aristada is not approved to treat children with schizophrenia.

Missed Dose

If you miss your appointment to receive Aristada, reschedule it as soon as possible. Depending on how many days have passed since your last dose, your healthcare provider may tell you to take Abilify (oral aripiprazole) for seven to 21 days after receiving Aristada. Alternatively, your healthcare provider may administer Aristada Initio (a different injectable form of aripiprazole) plus one Ability dose with your Aristada injection.

Try to help yourself remember to keep your appointments and take your medication routinely. If you miss too many doses, Aristada might be less effective at controlling your symptoms.

However, seek immediate medical attention if you think you're experiencing an overdose or life-threatening symptoms.

If you think you or someone else may have overdosed on Aristada, call a healthcare provider or the Poison Control Center (800-222-1222).

If someone collapses or isn't breathing after taking Aristada, call 911 immediately.
