Key Takeaways (quick facts)
What it is: An atypical antipsychotic used for schizophrenia, bipolar I disorder, adjunctive therapy in major depressive disorder, irritability in autism, and Tourette’s. Available as tablets, ODT, solution, and long-acting injections.
How it works: Modulates dopamine/serotonin (partial agonist activity), helping stabilize mood, thinking, and behavior.
Common side effects: Insomnia, restlessness/akathisia, headache, nausea; serious risks include metabolic changes, movement disorders, impulse-control problems, and boxed warnings.
LAI options: Abilify Maintena/Asimtufii (aripiprazole), and Aristada (aripiprazole lauroxil). Dosing schedules differ.
What Is Aripiprazole?
Aripiprazole is an atypical antipsychotic prescribed to help manage symptoms of schizophrenia, bipolar I disorder(including maintenance), as adjunctive therapy for major depressive disorder (MDD), for irritability associated with autism, and Tourette’s symptoms. It comes as oral tablets, orally disintegrating tablets, oral solution/film, and intramuscular long-acting injections administered by a clinician. Brand names include Abilify, Abilify Maintena, Abilify Asimtufii, and Aristada (aripiprazole lauroxil).

How Aripiprazole Works
Aripiprazole partially stimulates dopamine D2 receptors and affects serotonin receptors (notably 5-HT1A/5-HT2A). In practice, that “stabilizing” action can reduce hallucinations, improve mood, and help with agitation or disorganized thinking—without fully blocking dopamine like older antipsychotics. Patients often notice less sedation than with some peers, though restlessness/akathisia may occur.
FDA-Recognized Uses and Who It Helps
Schizophrenia (adults; adolescents for certain formulations)
Bipolar I disorder (acute mania/mixed episodes; maintenance in some forms)
Adjunct to antidepressants in MDD (adults)
Irritability associated with autistic disorder (pediatrics per labeling)
Tourette’s disorder (pediatric dosing applies)
Your prescriber may recommend aripiprazole when symptoms include hallucinations, delusions, severe mood swings, or disruptive irritability that has not responded to other treatments.
Dosing & Titration (Oral) — Adults and Youth
Important: Dosing is individualized. Do not change your dose without medical guidance.
Adults (typical label-based ranges)
Schizophrenia: Often 10–15 mg once daily to start; some patients need up to 30 mg/day.
Bipolar I (mania/mixed): Often 15 mg once daily; 10–15 mg with lithium/valproate.
Adjunct in MDD: Often 2–5 mg once daily to start (not usually >15 mg/day).
Pediatrics (when labeled)
Schizophrenia (13–17 y): Often titrated from 2 mg to 10 mg daily; max 30 mg/day.
Irritability in autism (6–17 y): Often 2 mg once daily initially, titrated to clinical response (not usually >15 mg/day).
How to take: Once daily, with or without food, at a consistent time. If insomnia is an issue, morning dosing can help for some patients.
Long-Acting Injectable (LAI) Aripiprazole: A Practical Guide
Long-acting injections can improve adherence and keep drug levels steadier.
Abilify Maintena® (aripiprazole) – monthly
Indication: Maintenance treatment of schizophrenia; also used for bipolar I maintenance.
Dose: Commonly 400 mg IM monthly (no sooner than 26 days between injections). Some patients step down to 300 mg monthly for tolerability. Oral overlap typically required at initiation.
Abilify Asimtufii® – extended interval (brand info varies by label)
Branded LAI aripiprazole with different interval options than Maintena; your clinician selects product/interval based on history and tolerability. (Consult full prescribing info.)
Aristada® (aripiprazole lauroxil) – monthly to q8wk (formulation-dependent)
Indication: Schizophrenia (adults).
Doses/Intervals: Multiple (e.g., 441, 662, 882 mg monthly; 882 mg q6wk; 1064 mg q8wk); ARISTADA INITIO® + single oral dose may enable rapid initiation per label.
Choosing an LAI: Consider prior response to oral aripiprazole, need for oral overlap, visit cadence, and insurance coverage. Your prescriber and care team will weigh side-effect history (e.g., akathisia) and preferred interval.
Side Effects & Safety
Common (often improve over time)
Insomnia, restlessness/anxiety/akathisia, headache, nausea. Practical tip: if sleep worsens, ask your clinician about morning dosing; address caffeine intake late in the day.
Metabolic & Neurologic
Weight gain, elevated blood sugar/cholesterol, and movement disorders (e.g., tardive dyskinesia; restlessness). Report persistent or disabling effects promptly.
Impulse-Control Problems
Rarely, urges like compulsive gambling, shopping, binge eating, or hypersexuality can occur. Contact your clinician immediately if you notice new or increasing urges.
Boxed Warnings & Serious Risks
Suicidality risk (especially in younger patients) and increased mortality in elderly patients with dementia-related psychosis appear on antipsychotic boxed warnings. Aripiprazole is not approved for dementia-related psychosis.
Emergency symptoms: high fever, confusion, stiff muscles, sweating, irregular heartbeat (neuroleptic malignant syndrome); uncontrolled movements; signs of high blood sugar (excessive thirst/urination); severe rash; or allergic reaction—seek urgent care.
Interactions: Alcohol, Cannabis, and Other Medicines
Alcohol
Alcohol can worsen drowsiness, dizziness, judgment, and may increase the risk of orthostatic symptoms. Most clinicians recommend avoiding or minimizing alcohol on aripiprazole.
Cannabis
Cannabis (THC) may increase sedation, impair coordination, and complicate mood or anxiety symptoms. Discuss any cannabis use with your prescriber.
Key Drug Interactions (CYP Pathways)
CYP2D6 inhibitors (e.g., fluoxetine, paroxetine, bupropion) and CYP3A4 inhibitors (e.g., ketoconazole) can increase aripiprazole levels → your dose may need adjustment.
CYP3A4 inducers (e.g., carbamazepine, rifampin) can decrease levels → dose adjustments or alternative therapy may be considered.
Always provide a full med/supplement list to your clinician (including grapefruit products).

How Fast Does It Work? Onset, Half-Life, and Duration
People may notice calmer thinking or less agitation within days, but full benefit for mood/psychosis often takes several weeks. Aripiprazole’s long half-life supports once-daily dosing and LAI use; steady state and symptom stabilization are gradual. Ask your prescriber how they’ll track progress and when to reassess.
Who Should Not Take Aripiprazole?
Elderly patients with dementia-related psychosis (not an approved use; increased mortality risk).
History of tardive dyskinesia, NMS, seizure disorders, diabetes/metabolic syndrome, cardiovascular disease, or orthostatic hypotension.
Pregnancy/Lactation: decisions are individualized; discuss risks/benefits and alternatives with your OB-psychiatry team.
Practical Tips
Insomnia/restlessness? Morning dosing, caffeine timing, and activity pacing can help; report persistent akathisia.
Missed dose (oral): If it’s close to your usual time, take it; otherwise skip—don’t double up. For LAIs, call your clinic for catch-up advice.
Stopping: Do not stop suddenly unless directed; your clinician may taper to reduce relapse/withdrawal-like symptoms.

Frequently Asked Questions About Aripiprazole
What is aripiprazole used for?
Aripiprazole (Abilify) is prescribed to treat schizophrenia, bipolar I disorder, major depressive disorder (as an add-on), irritability linked to autism, and Tourette’s disorder. It helps stabilize mood, reduce hallucinations, and manage severe behavioral symptoms.
How long does aripiprazole take to start working?
Some people notice reduced agitation or clearer thinking within a few days. However, it often takes two to six weeks for the full effects on mood and psychosis symptoms to appear.
What is the usual dose of aripiprazole?
The starting dose depends on the condition. For schizophrenia, adults usually begin at 10–15 mg daily. In depression, doses are often as low as 2–5 mg daily. Maximum doses vary by diagnosis, so always follow your prescriber’s instructions.
What are the most common side effects of aripiprazole?
Common side effects include insomnia, restlessness (akathisia), headache, nausea, and dizziness. Many people tolerate these well, but you should speak with your prescriber if symptoms are severe or persistent.
Can aripiprazole cause weight gain?
Yes, weight gain is possible. Aripiprazole may affect metabolism and increase risks for diabetes and cholesterol changes. Regular check-ups for weight, blood sugar, and lipids are recommended.
Can I drink alcohol while taking aripiprazole?
It’s best to avoid alcohol. Drinking can increase drowsiness, dizziness, and impaired judgment while on aripiprazole. Mixing the two may also worsen mood or anxiety symptoms.
What’s the difference between Abilify Maintena, Abilify Asimtufii, and Aristada?
All are long-acting injections (LAIs) of aripiprazole.
Abilify Maintena is given monthly.
Abilify Asimtufii offers extended dosing intervals.
Aristada (aripiprazole lauroxil) can be given monthly to every eight weeks.
Your prescriber will choose the right one based on your needs and treatment goals.
Why do I feel restless on aripiprazole?
That sensation is called akathisia, a movement-related side effect that causes inner restlessness or an urge to move. If this happens, let your provider know—dose adjustments or supportive medications can help.
Can aripiprazole trigger gambling or other urges?
Yes, although rare, aripiprazole has been linked to impulse-control problems, such as gambling, binge eating, or compulsive shopping. If you notice these urges, contact your doctor immediately.
Is aripiprazole safe during pregnancy or breastfeeding?
Aripiprazole may be used in pregnancy or while breastfeeding only if the benefits outweigh the risks. Discuss your situation with your prescriber, as alternative options may be considered for maternal and infant safety.
