Imagine finding a medication that helps stabilize your mood, reduce hallucinations, or improve focus, but also comes with a list of potential side effects. This is the reality for many people taking aripiprazole, a widely prescribed antipsychotic.

Aripiprazole (brand name Abilify) is a second-generation antipsychotic used to treat various mental health conditions, including schizophrenia, bipolar disorder, and depression (as an adjunct). While it can be highly effective for these conditions, it’s essential to understand its possible side effects and how to manage them.

This comprehensive guide walks through the common and rare side effects of aripiprazole, offering insights into what to watch for and when to seek medical help.

Understanding Aripiprazole and Its Uses

Before diving into side effects, it's helpful to understand what aripiprazole is, what it's used for, and how it works in the brain.

What is Aripiprazole?

Aripiprazole is a dopamine partial agonist and atypical antipsychotic that helps balance brain chemistry. It's often chosen for its unique mechanism of action, which allows it to stabilize dopamine levels, reducing both positive (e.g., hallucinations) and negative (e.g., social withdrawal) symptoms.

Conditions Treated with Aripiprazole

Aripiprazole is FDA-approved for the treatment of several mental health conditions, including:

  • Schizophrenia (adults and adolescents)
  • Bipolar I disorder (manic or mixed episodes)
  • Adjunctive treatment for major depressive disorder (MDD)
  • Irritability associated with autism spectrum disorder (ASD)
  • Tourette's syndrome (children and adolescents)

It is also sometimes used off-label for conditions like borderline personality disorder (BPD), generalized anxiety disorder (GAD), and post-traumatic stress disorder (PTSD). However, a healthcare provider should guide these uses.

How Aripiprazole Works in the Brain

Aripiprazole acts on dopamine D2 and serotonin 5-HT1A and 5-HT2A receptors, making it a partial agonist for dopamine and a serotonin antagonist. This unique combination helps:

  • Stabilize mood
  • Reduce hallucinations and delusions
  • Improve emotional regulation
  • Reduce aggression and irritability

This dual action is thought to reduce the risk of some side effects, like weight gain, compared to other antipsychotics, though it can still cause a range of unwanted effects.

Common Side Effects of Aripiprazole

Like all medications, aripiprazole can cause side effects. Most are mild and may improve as your body adjusts to the medication.

Gastrointestinal Effects

  • Nausea and Vomiting:  Nausea and vomiting are the most frequently reported side effects. These typically occur when starting treatment or after a dose increase. Taking the medication with food or splitting the dose may help.
  • Constipation:  Constipation can happen in some patients, particularly at higher doses. Increasing dietary fiber, fluid intake, and regular exercise may reduce this effect.

Neurological Effects

  • Headaches are common but typically mild. They often improve as the body adjusts to the medication. Over-the-counter pain relievers may be used, but check with your doctor first.
  • Dizziness and Drowsiness: Some patients report feeling lightheaded, especially after standing up quickly. Drowsiness may affect daily activities, including driving; caution is advised until you know how the medication affects you.

Psychological Effects

  • Anxiety and Restlessness (Akathisia): Described as a sense of inner restlessness or inability to sit still. More common at higher doses or during early treatment. Dose adjustments or add-on medications like propranolol or benzodiazepines may help reduce these side effects.
  • Insomnia: Trouble falling or staying asleep is sometimes reported. Avoiding caffeine, establishing a bedtime routine, or adjusting the dosing schedule may improve sleep.

Metabolic Changes

  • Weight Gain: Weight gain is less common than with other antipsychotics like olanzapine or quetiapine, but still possible. Regular monitoring of weight, blood sugar, and cholesterol is recommended.

Serious Side Effects and Warnings

While rare, some side effects can be serious and require urgent medical attention.

Neuroleptic Malignant Syndrome (NMS)

  • NMS is a rare but life-threatening condition characterized by fever, muscle rigidity, altered mental status, and autonomic instability.
  • It requires immediate medical intervention and discontinuation of the medication. 

Tardive Dyskinesia

  • Tardive dyskinesia is characterized by involuntary, repetitive muscle movements, often in the face, tongue, or limbs.
  • It can become permanent if not identified early. Regular movement assessments are recommended.

Increased Risk of Death in Elderly Patients with Dementia-Related Psychosis

  • Aripiprazole is not approved for dementia-related psychosis in the elderly due to a higher risk of stroke and death.
  • This risk is highlighted in the FDA Black Box Warning

Suicidal Thoughts and Behaviors in Children, Adolescents, and Young Adults

  • Increased risk in patients 24 years old and younger.
  • Close monitoring is essential, especially in the early weeks of treatment or after a dose change.
  • This risk is also highlighted in the FDA Black Box Warning

Managing Aripiprazole Side Effects

Proper side effect management is essential for patients on aripiprazole to ensure both safety and long-term treatment success. While many side effects are mild and improve over time, others may require adjustments to the treatment plan.

Strategies for Coping with Common Side Effects

Managing common side effects can improve medication adherence and overall quality of life. Some practical strategies include:

Nausea and Vomiting:

  • Take the medication with food or a full glass of water.
  • Consider eating smaller, more frequent meals and avoiding spicy or greasy foods.
  • Ginger tea or peppermint may help settle the stomach, but check with your healthcare provider before adding herbal remedies.

Dizziness and Drowsiness:

  • Stand up slowly from sitting or lying positions to reduce the risk of lightheadedness.
  • Avoid driving or operating heavy machinery until you know how the medication affects you.

Weight Gain and Increased Appetite:

  • Focus on a balanced diet rich in fiber, lean protein, and whole grains.
  • Engage in regular physical activity like walking, swimming, or strength training.
  • Monitor weight regularly to catch early signs of unwanted weight gain.

Anxiety and Restlessness (Akathisia):

  • Practice deep breathing, meditation, or yoga to reduce stress.
  • Talk to your healthcare provider about adjusting the dose or adding a beta-blocker like propranolol if restlessness worsens.

Insomnia:

  • Practice good sleep hygiene by avoiding caffeine and electronics close to bedtime and maintaining a regular sleep schedule.
  • Consider adjusting the timing of your dose if it interferes with sleep.

When to Seek Medical Attention

While many side effects are manageable, some require immediate medical attention, including:

  • Severe dizziness or fainting
  • Muscle stiffness, tremors, or uncontrollable movements
  • Signs of a severe allergic reaction, like swelling of the face or throat, hives, or difficulty breathing
  • Unusual changes in mood or behavior, including suicidal thoughts

Never ignore severe symptoms or assume they will go away on their own. Early medical intervention can prevent complications and improve long-term outcomes.

Adjusting Dosage and Treatment Plans

If side effects persist or significantly impact daily life, your healthcare provider may:

  • Lower the Dose: Reducing the dose can sometimes alleviate side effects without compromising the medication's effectiveness.
  • Change the Dosing Schedule: Moving the dose to the morning or evening may reduce side effects like insomnia or daytime drowsiness.
  • Switch Medications: In some cases, switching to a different atypical antipsychotic with a more favorable side effect profile may be necessary.

Patients should never adjust their dose or stop taking aripiprazole without medical guidance, as this can lead to withdrawal symptoms or a worsening of psychiatric symptoms.

Lifestyle Changes to Mitigate Side Effects

Minor lifestyle adjustments can make a big difference in reducing side effects:

  • Exercise Regularly: Physical activity can reduce weight gain, improve mood, and boost energy levels.
  • Stay Hydrated: Drinking enough water can reduce the risk of constipation and dizziness.
  • Sleep Hygiene: Create a calming bedtime routine to reduce insomnia and improve sleep quality.

Aripiprazole in Special Populations

Certain patient groups may experience different side effects or require special monitoring while taking aripiprazole.

Side Effects in Children and Adolescents

  • Weight Gain: Children and teens may be more susceptible to weight gain and metabolic changes. Regular weight checks and dietary counseling are recommended.
  • Mood and Behavior Changes: Young patients may be at a higher risk for suicidal thoughts and impulse control issues. Close monitoring is essential, especially in the first few months of treatment.
  • Motor Side Effects: Children may also be more prone to akathisia (restlessness) or extrapyramidal symptoms (EPS).

Considerations for Elderly Patients

  • Increased Risk of Stroke and Death: Aripiprazole carries a black box warning for increased mortality in elderly patients with dementia-related psychosis. It is not approved for this use.
  • Fall Risk: Dizziness and orthostatic hypotension (sudden drops in blood pressure when standing up) can increase the risk of falls and fractures.
  • Cognitive Effects: Elderly patients may experience confusion or cognitive decline, requiring careful dose adjustments.

Pregnancy and Breastfeeding

  • Pregnancy: Aripiprazole should be used during pregnancy only if your healthcare provider determines that the potential benefits outweigh the risks. There is a risk of withdrawal symptoms or movement disorders in newborns exposed to antipsychotics during the third trimester. 
  • Breastfeeding: Not generally recommended, as the drug can pass into breast milk and potentially affect the infant’s development and behavior.

Patients with Pre-existing Medical Conditions

  • Heart Disease: Patients with heart conditions may be at increased risk for QT prolongation or arrhythmias and should have regular EKGs.
  • Diabetes or Prediabetes: Regular blood sugar checks are advised, as antipsychotics can increase the risk of metabolic syndrome.
  • Seizure Disorders: Aripiprazole may lower the seizure threshold, increasing the risk of seizures in susceptible individuals.

Frequently Asked Questions (FAQs)

Q: How long do aripiprazole side effects typically last?
A: Common side effects, like nausea, dizziness, and restlessness, often improve within the first 1 to 2 weeks as your body adjusts to the medication. However, some side effects, such as weight gain or metabolic changes, may persist longer. Contact your healthcare provider if side effects are severe or don't improve.

Q: Can I drink alcohol while taking aripiprazole?
A: It is generally not recommended to drink alcohol while taking aripiprazole. Alcohol can increase drowsiness, dizziness, and impaired coordination, potentially worsening side effects. It may also interfere with the effectiveness of the medication.

Q: What should I do if I miss a dose of aripiprazole?
A: If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue your regular schedule. Do not take two doses simultaneously to make up for a missed dose. Always follow your healthcare provider's instructions.

Q: Are there any dietary restrictions while taking aripiprazole?
A: There are no specific dietary restrictions, but maintaining a balanced diet is recommended, as aripiprazole may increase appetite and weight gain in some patients. Reducing high-fat, high-sugar foods can help manage this risk. Avoid grapefruit and grapefruit juice if advised by your healthcare provider, as they may interfere with how the medication is processed in the body.

Q: How does aripiprazole interact with other medications?
A: Aripiprazole can interact with various medications, including:

  • CYP3A4 inhibitors (e.g., ketoconazole) and CYP2D6 inhibitors (e.g., fluoxetine, paroxetine) which can increase aripiprazole levels.
  • CYP3A4 inducers (e.g., carbamazepine), which can reduce aripiprazole levels.
  • Blood pressure medications, which may increase the risk of low blood pressure.
  • CNS depressants (e.g., benzodiazepines, opioids), which can increase drowsiness or sedation.

Always inform your healthcare provider about all medications, supplements, and herbal products you are taking to avoid potential drug interactions.
