Aripiprazole: 6 things you should know
Medically reviewed by C. Fookes, BPharm Last updated on Jan 16, 2019.
1. How it works
- Aripiprazole is used to treat psychotic symptoms. The exact way aripiprazole works is unknown; however, experts suggest it rebalances dopamine and serotonin levels in the brain.
- Aripiprazole belongs to the class of medicines called atypical antipsychotics. Atypical means it is less likely than older antipsychotics to cause side effects, and more likely to be effective in the treatment of symptoms such as lack of motivation and social withdrawal.
- Used to relieve symptoms of psychosis (such as delusions and hallucinations) and agitation associated with schizophrenia and manic or mixed episodes of bipolar I disorder.
- May also be used in addition to other medications in the treatment of depression.
- Aripiprazole in small dosages may be also used to relieve irritability and symptoms of aggression, temper tantrums, and mood fluctuations in children with autistic disorder.
- May help reduce tic severity in Tourette's syndrome.
- Generic aripiprazole is available.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- Akathisia (an inner restlessness), sedation, headache, insomnia, agitation, anxiety, nausea, tremor. Other reasonably common side effects include constipation, vomiting, dry mouth, stomach upsets and extrapyramidal symptoms (such as restlessness, tremor, uncontrolled muscle contractions). May also cause difficulty swallowing.
- Should not be used for the treatment of dementia-related psychosis in elderly people as associated with a higher risk of death.
- If being used as an adjunct therapy in the treatment of depression, monitor for worsening depression, agitation or mood changes.
- May cause a drop in blood pressure on standing, particularly during the initial dose titration period; dosage may need reducing. May not be suitable for people with known cardiovascular disease (history of a heart attack, angina, heart failure, or arrhythmia), stroke, seizure disorders, and people at risk of dehydration.
- Blood levels may need monitoring as aripiprazole can cause numbers of white blood cells to decrease.
- May increase blood sugar levels. People with a history of diabetes or at risk of diabetes should be monitored closely. Less likely than some other antipsychotics to cause undesirable changes in blood cholesterol and lipid levels or to cause weight gain.
- Potentially irreversible tardive dyskinesia can develop, even with low dosages used short-term. Symptoms include facial grimacing, repetitive chewing, and tongue thrusting.
- Rarely, may cause Neuroleptic Malignant Syndrome; symptoms include high body temperature, muscle rigidity, and mental disturbances; discontinue immediately and seek urgent medical advice.
- May interact with a number of drugs, including benzodiazepines, carbamazepine, fluoxetine, and itraconazole. See prescribing information for a full list of interactions.
Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

- May be administered with or without food.
- Several brands of aripiprazole are available. Formulations include oral tablets, orally-disintegrating tablets, and an oral solution. Disintegrating tablets should not be removed from their blister until ready to administer. Dry hands should be used to peel back the foil on the blister rather than attempting to pop the tablet through the foil. The tablet should then be placed on the tongue. May be taken with or without liquid, but do not attempt to split the tablet.
- May cause sedation or impair judgment skills and affect your ability to drive or operate machinery. Avoid alcohol.
- Avoid overheating and dehydration.
- Seek urgent medical advice if you develop unusual body movements, confusion, high fever, lightheadedness, fainting, seizures, have problems controlling your body temperature, or difficulty swallowing.
- Aripiprazole may make you feel dizzy when going from a sitting or lying down position to standing. This may increase your risk of falls. Stand up slowly and remove any fall hazards from your home (such as loose rugs).
- Talk with your doctor if you develop any worrying side effects such as uncontrollable facial grimacing, restlessness, severe dizziness, or severe abdominal discomfort.
- Tell your doctor if you are intending to become pregnant and you are taking aripiprazole as your doctor may wish to change you to a different medication. Aripiprazole is incompatible with breastfeeding.
6. Response and Effectiveness
- Peak blood levels are reached within three to five hours of taking oral aripiprazole. Effects are long lasting, so aripiprazole is usually taken once daily.
- May take up to two weeks to achieve stable blood concentrations.
- Target dosages of 10-15mg per day of aripiprazole are recommended for schizophrenia; dosages above 15 mg/day have not been found to be more effective than 15 mg/day.
- Dosage reductions may be needed for people known to be poor metabolizers of drugs like aripiprazole, or in people taking other medications known to interfere with the hepatic enzymes CYP2D6 and CYP3A4. Conversely, a dosage increase of aripiprazole may be needed when given with medications that induce CYP3A4.
