Aripiprazole Risks, Warnings, and Complications


Aripiprazole can cause or worsen health problems in some people. Talk to your doctor about other treatment options for your condition if you are at an increased risk of complications from this medicine. Some of the risks of aripiprazole use include:

  • INCREASED RISK OF DEATH IN ELDERLY PATIENTS WITH DEMENTIA: There is an FDA drug safety communication (black box warning) about the increased risk of death when aripiprazole is used to treat dementia-related psychosis in elderly patients. This medication is not FDA-approved to treat dementia-related psychosis in people over the age of 65 years.

  • INCREASED RISK OF SUICIDALITY: Aripiprazole is sometimes prescribed to adults with major depressive disorder as an adjunctive (add-on) medication along with antidepressant drugs. Antidepressants are linked to an increased risk of suicidal thinking and behaviors, especially in people below the age of 24 years. If you are taking antidepressant medications with or without aripiprazole, your healthcare provider will monitor you carefully for worsening depression, suicidal thoughts or behaviors, or any unusual changes in mood. Other people in your household should know when and how to seek help if you are unable to do so yourself.

  • NEUROLEPTIC MALIGNANT SYNDROME: Aripiprazole and other atypical antipsychotics can trigger a rare but life-threatening condition called neuroleptic malignant syndrome (NMS). Symptoms include high fever, fast or irregular heartbeat, confusion, muscle stiffness, and sweating. Seek emergency medical attention if you develop any of these symptoms while taking aripiprazole. Your healthcare provider will likely discontinue treatment with aripiprazole if this happens.

  • TARDIVE DYSKINESIA: Aripiprazole and other antipsychotic drugs can cause involuntary, uncontrolled movements (extrapyramidal symptoms) called tardive dyskinesia. Elderly patients are at a higher risk of this complication. Higher doses of the medicine and long-term treatment increase the likelihood of developing tardive dyskinesia and of the involuntary movements being irreversible. The symptoms may partially or completely go away when treatment with antipsychotic medications is stopped. Your doctor will weigh the risks versus benefits of prescribing antipsychotic drugs to you. They will reserve these medications for when you do not respond to other equally effective and potentially less harmful medications. Your provider will also review the need to continue treatment with aripiprazole periodically. Tell your doctor without delay if you develop restlessness, inability to sit still, or uncontrolled movements like grimacing, lip smacking, or eye blinking.

  • HYPERGLYCEMIA AND WEIGHT GAIN: There are reports that aripiprazole can raise blood sugar levels and cause or worsen diabetes. The hyperglycemia (high blood sugar) usually resolves when the medicine is stopped, but it can sometimes persist even after discontinuation of the antipsychotic medicine. In addition, antipsychotic drugs can also cause high cholesterol and weight gain. These changes can increase your risk of heart disease and stroke. Your healthcare provider will discuss preventive measures to lower your risk of metabolic disorders.

  • ORTHOSTATIC HYPOTENSION: Aripiprazole can cause orthostatic hypotension (a drop in blood pressure when changing positions from sitting or lying to standing). The risk is highest when you first start taking aripiprazole. Tell your doctor if you feel dizzy when getting out of bed or if you have a fast, racing heartbeat.

  • LOW WHITE BLOOD CELL COUNTS: Aripiprazole has been linked to low white blood cells, which are cells that fight infections. Your doctor may order blood tests to check your white blood cell counts before starting aripiprazole treatment. Tell your doctor right away if you develop a fever or symptoms of infection while you are on this medicine. 

  • SEIZURES: Aripiprazole can increase the risk of having seizures (convulsions). This medication should be used with caution if you have a history of seizures or other health conditions that increase your risk of seizures. 

  • COGNITIVE AND MOTOR IMPAIRMENTS: Aripiprazole can cause sedation (drowsiness) and impaired thinking, judgment, and motor control. Do not drive or perform other hazardous activities until you know how this medicine affects you. Tell your doctor if you notice severe sleepiness or problems with thinking while on aripiprazole.

  • BODY TEMPERATURE REGULATION: Aripiprazole can affect your body’s ability to regulate its core temperature. Be careful during activities that cause increased body temperature, such as strenuous physical exercise, exposure to extreme heat, or dehydration. Before starting treatment, tell your doctor if you are taking anticholinergic drugs.

  • DYSPHAGIA: Aripiprazole may cause dysphagia (problems with swallowing) and increase the risk of aspiration pneumonia, especially in elderly patients and those with Alzheimer’s dementia. This medicine should be used with caution in such individuals.

  • COMPULSIVE OR UNCONTROLLABLE URGES: Aripiprazole has been linked to impulsiveness and problem behaviors like compulsive gambling, eating, shopping, and increased sexual urges. Tell your provider immediately if you notice any problems with impulse control. A family member should be aware of this risk so that they can seek care if you are unable to do so yourself. Your doctor may reduce your dose or stop aripiprazole and switch you to some other medication if you develop uncontrolled urges.


Precautions Before Starting Aripiprazole

Tell your doctor if you have had an unusual or allergic reaction to aripiprazole, any of the active or inactive ingredients in aripiprazole formulations, other atypical antipsychotics, or any other medications. Your pharmacy can give you a list of ingredients.

Give your doctor or pharmacist a complete list of your medications, including prescription drugs, nonprescription drugs, vitamins, supplements, and herbal products such as St. John’s Wort. This can help avoid possible interactions between aripiprazole and your other medicines.

Give your doctor a complete medical history. Aripiprazole may not be right for people with certain health conditions, such as dehydration, vomiting, diarrhea, irregular heartbeat, heart failure, heart attack, heart disease, low or high blood pressure, high cholesterol, stroke or mini-strokes, seizures, low blood cell counts, balance problems, or swallowing problems. Also, inform your doctor if you have a personal or family history of substance abuse (alcohol, illegal drugs, or prescription drugs), diabetes, bipolar disorder, impulse control problems, or obsessive-compulsive disorder. Tell your healthcare provider if you ever had to discontinue a mental illness medication because of intolerable or severe adverse effects.

Tell your doctor if you are currently pregnant, could be pregnant, are planning a pregnancy, or are breastfeeding. Aripiprazole can be harmful to the newborn baby if the mother takes this medicine during late pregnancy.

Precautions During Use of Aripiprazole

Keep all your medical and lab appointments while on aripiprazole. Tell your health care professional if your symptoms do not improve or get worse after a few weeks of treatment with this medicine. Do not change the dose or dosing frequency or stop taking aripiprazole without talking to your doctor first.

Aripiprazole can make you feel drowsy and dizzy. Exercise caution while driving and during other potentially hazardous activities until you are sure you don’t have these side effects. Alcohol can make these side effects worse. Avoid drinking alcohol while on aripiprazole.

Aripiprazole can cause lightheadedness, dizziness, and fainting upon changing positions from sitting or lying to standing. When you get out of bed, do so slowly by resting your feet on the ground for a short period before standing up. Tell your doctor if the dizziness is severe or does not go away after a few days.

Aripiprazole can cause high blood sugar and may cause or worsen diabetes. If you have a diagnosis of diabetes, talk to your doctor about how often you should measure your blood sugar levels. The oral solution of aripiprazole contains sugar and may affect blood glucose levels. Tell your doctor if you develop signs and symptoms such as increased thirst, increased hunger, frequent urination, weakness, and blurred vision. Seek emergency medical care if you develop signs of diabetic ketoacidosis, such as nausea, vomiting, dry mouth, fruity-smelling breath, shortness of breath, and loss of consciousness. 

Aripiprazole can make it harder for you to cool down. Avoid strenuous exercise in hot weather. Stay well hydrated. Seek immediate medical care if you develop signs and symptoms of overheating, such as dizziness, weakness, thirst, weak and rapid pulse, or muscle cramps. 

The orally disintegrating tablets of aripiprazole contain phenylalanine and are not suitable for people with a condition called phenylketonuria (PKU). 

Talk to your provider about eating grapefruit and drinking grapefruit juice while on aripiprazole.

In children with autism spectrum disorders and Tourette’s syndrome, antipsychotic drugs such as aripiprazole are part of a comprehensive treatment plan that includes counseling, psychotherapy, and special education plans. Follow your child’s provider’s recommendations to get the maximum benefit from this medicine. 

Tell all your healthcare providers you are on aripiprazole, especially before any surgical procedures, including dental treatments.

Tell your healthcare professional without delay if you become pregnant while on aripiprazole.

Aripiprazole Drug Interactions

Taking aripiprazole with certain other drugs can affect how the medicines work. Possible interactions between aripiprazole and other medications can increase the risk of serious adverse events. Your doctor may change the dose of your medications, switch you to another medication, or monitor you carefully for side effects if there are known interactions between aripiprazole and your other medicines. Aripiprazole can have drug interactions with the following medications:

  • Antidepressants such as fluoxetine (Prozac, Sarafem), nefazodone, paroxetine (Paxil, Pexeva) 
  • Antidepressants and smoking cessation aids such as bupropion (Wellbutrin) 
  • Antifungal medications such as ketoconazole and itraconazole (Onmel, Sporanox)
