What is Aripiprazole?

Aripiprazole is an atypical antipsychotic medication that works by balancing certain chemicals in the brain.

This medication is used to treat a variety of mental health conditions, including schizophrenia, bipolar disorder, and depression.

Uses of Aripiprazole

Aripiprazole is primarily used to treat symptoms of schizophrenia, such as delusions, hallucinations, disordered thinking, and abnormal behavior.

It is also used to treat manic and mixed episodes associated with bipolar disorder and major depressive disorder.

Off-label use: Delusional disorder

In addition to its approved uses, aripiprazole is sometimes prescribed off-label for the treatment of delusional disorder.

Delusional disorder is a rare condition characterized by fixed, false beliefs that persist despite evidence to the contrary.

Aripiprazole can help alleviate some of the symptoms of delusional disorder by reducing the severity and frequency of delusions.

Dosing guidelines for Aripiprazole

The dosing of aripiprazole for delusional disorder is based on expert opinion, as there are no established guidelines for this specific use.

The recommended starting dose is 2-5 mg once daily, with gradual increases up to 10 mg per day if needed.

The dose can be increased further after a week at a time based on response and tolerability, up to a maximum of 30 mg per day.

Potential side effects of Aripiprazole

Like all medications, aripiprazole can cause side effects. Common side effects include headache, dizziness, drowsiness, nausea, vomiting, and constipation. Some people may also experience weight gain, increased appetite, or difficulty sleeping.

Less common side effects of aripiprazole include tardive dyskinesia, a movement disorder that can cause repetitive, involuntary movements of the face and body.

Aripiprazole can also increase the risk of developing diabetes or high cholesterol. Patients should be monitored for signs of these conditions and treated accordingly.


Aripiprazole is a powerful medication that can be effective in treating a variety of mental health conditions, including delusional disorder.

While the dosing guidelines for delusional disorder are based on expert opinion, this medication has been shown to be effective in reducing the severity and frequency of delusions.

Patients should be aware of the potential side effects and monitored regularly while taking aripiprazole. As with any medication, it is important to discuss the risks and benefits with a healthcare provider before starting treatment.
