Is This Information Right for Me?

This information is for you if

  • A doctor has suggested one of these medicines (listed below) for you or someone you care for. These medicines are called “antipsychotics” because they were made to treat severe mental illnesses such as psychosis. Antipsychotics are now used for many mental health conditions and symptoms, not just psychosis.
    • Aripiprazole (Abilify®)
    • Olanzapine (Zyprexa®)
    • Quetiapine (Seroquel®)
    • Risperidone (Risperdal®)
    • Ziprasidone (Geodon®)
  • A doctor has said that you or someone you care for has one of these conditions:
    • Dementia
    • Eating disorders (anorexia nervosa)
    • Generalized anxiety disorder
    • Obsessive compulsive disorder (OCD)
    • Post-traumatic stress disorder (PTSD)
    • Severe depression
    • Substance abuse

Evidence on the use of antipsychotics for some of these conditions is limited. See the Benefits of Antipsychotics by Condition table to find out if there is information for your condition. Definitions of these conditions are below.

This information may not be helpful to you if

  • A doctor has not suggested an antipsychotic for you or someone you care for.
  • Your doctor has suggested a different antipsychotic than those listed above, such as asenapine (Saphris®), iloperidone (Fanapt®), and paliperidone (Invega®). There is not enough research available about these drugs for conditions other than psychosis or bipolar disorder.
  • You are taking the antipsychotic clozapine (Clozaril®, FazaClo®). This medicine can cause a serious side effect and requires special care from your doctor.
  • You are under 18. This information is from research on adults.

What will this summary tell me?

This summary will tell you about research on how well some antipsychotic medicines work for conditions other than psychosis and bipolar disorder. It will also tell you about research on the risks of side effects for these medicines.

Where does the information in this summary come from?

The information in this summary is from a report on antipsychotics taken for a variety of conditions. The report reviewed 170 studies published before May 2011 about the effectiveness of these drugs. It also reviewed 180 studies published before May 2011 about the side effects of these drugs. This information can help you talk with your doctor about what medicine may be right for you.

Understanding Antipsychotics

Why do people take antipsychotic medicines?

Antipsychotic medicines were made to help people who have psychosis, a symptom of severe mental illnesses such as schizophrenia or bipolar disorder. These medicines are now used for many other conditions (listed below). These medicines are not made to cure these conditions, but to help relieve symptoms and improve quality of life.

  • Dementia: Problems with thinking, memory, communication, or movement. Sometimes dementia causes people to yell, fight, or see things that are not there.
  • Eating disorders: Anorexia nervosa (not eating enough food because you think you are overweight even when you are underweight and very thin).
  • Generalized anxiety disorder: Frequent and very strong feelings of fear and worry that go beyond the usual everyday stress that people feel.
  • Obsessive compulsive disorder (OCD): Feeling anxious from thoughts and fears (obsessions) that lead you to repeat actions (compulsions) without a good reason. Examples include washing your hands repeatedly because you fear germs or repeatedly checking the door lock because you fear intruders.
  • Post-traumatic stress disorder (PTSD): Anxiety, panic, or depression based on a traumatic event in your life.
  • Severe depression: Ongoing feelings of sadness, worthlessness, and hopelessness.
  • Substance abuse: Overusing or becoming dependent on alcohol, drugs, or other substances.

You may also be taking other medicines to treat these conditions, such as antidepressants or other anxiety medicines. Antipsychotics may be added to these other medicines, or may replace them if those medicines did not work, to help treat your condition.

What does research say about how well antipsychotics work for different conditions?

Antipsychotic medicines studied in the research for this summary include:

  • Aripiprazole (Abilify®)
  • Olanzapine (Zyprexa®)
  • Quetiapine (Seroquel®)
  • Risperidone (Risperdal®)
  • Ziprasidone (Geodon®)

Antipsychotic medicines NOT included in this summary:

  • Clozapine (Clozaril®, FazaClo®) was not included because it can cause a serious side effect and requires special care from your doctor.
  • Asenapine (Saphris®), iloperidone (Fanapt®), and paliperidone (Invega®) were not included because there was not enough research available about them for conditions other than psychosis.

Not every antipsychotic medicine has been studied for each condition. For some medicines, researchers are able to say how many people saw a benefit during studies of those medicines. This information may help you understand how likely you may be to see the same benefit.

Benefits of Antipsychotics by Condition

ConditionWhat benefit?Which medicine?How likely is the benefit?
DementiaImproved symptoms such as aggression, delusions (believing things that are not true or logical), or hallucinations (seeing things or hearing voices that are not there)
Did NOT improve problems with thinking or memory
  • All antipsychotics included in this summary, except for ziprasidone (Geodon®)
  • There are not enough studies on ziprasidone (Geodon®) to know if it improves symptoms
Although doctors may see small improvements in tests that score symptoms, there is not enough research to know how many are likely to see the same result.
Generalized Anxiety DisorderImproved symptoms by about 50 percent
  • Quetiapine (Seroquel®)
For every 8 people taking this medicine, 1 saw this benefit.
Severe Depression*Improved symptoms by at least 50 percent or removed all symptoms
  • Aripiprazole (Abilify®), olanzapine (Zyprexa®), quetiapine (Seroquel®), or risperidone (Risperdal®) combined with an antidepressant
  • Quetiapine XR (Seroquel XR®) taken by itself
The research for this summary only measured the likelihood of this benefit for risperidone (Risperdal®) and quetiapine XR (Seroquel XR®):
  • For every 7 people taking risperidone (Risperdal®), 1 saw improved symptoms.
  • For every 8 people taking risperidone (Risperdal®), 1 saw all symptoms removed.
  • For every 6 people taking quetiapine XR (Seroquel XR®), 1 saw improved symptoms.
  • For every 13 people taking quetiapine XR (Seroquel XR®), 1 saw all symptoms removed.
Post-traumatic Stress Disorder (PTSD; related to military combat)Improved symptoms slightly
  • Risperidone (Risperdal®) combined with an antidepressant
Although a benefit was seen for some people, there is not enough research to know how many are likely to see the same result.
Obsessive Compulsive DisorderImproved symptoms by at least 25 to 35 percent
  • Risperidone (Risperdal®) combined with an antidepressant
For every 5 people taking this medicine, 1 saw this benefit.
Eating Disorders (anorexia nervosa)Did NOT help people gain weight
  • Olanzapine (Zyprexa®)
There was not much difference between those who took this medicine and those who did not.
Substance AbuseDid NOT help people reduce the amount of alcohol or drugs they took or the amount of time they stayed drug or alcohol free
  • All antipsychotics included in this summary
There was not much difference between those who took an antipsychotic and those who did not.
*

The U.S. Food and Drug Administration (FDA) has approved the antipsychotics aripiprazole (Abilify®), olanzapine (Zyprexa®), and quetiapine (Seroquel®) to add to other medicines for treating severe depression.

Making a Decision

What should I think about when deciding?

There are several things to consider when deciding if an antipsychotic medicine is right for you or someone you care for. Only you and your doctor can decide whether any medicine’s ability to help is worth the risk of a serious side effect. Each person responds differently to different antipsychotic medicines. Your doctor may try several medicines before finding the right one.

You and your doctor should discuss:

  • How well medicines other than antipsychotics are working or might work to improve your symptoms.
  • The risk for a serious side effect based on your medical history and how long the side effect might last.
  • The trade-offs between the specific benefits and side effects of each medicine for you or someone you care for.
  • How likely the medicines will cause weight gain or will require changes to your lifestyle.
  • Ways your doctor can help you notice side effects so they can be treated or so the medicine you are taking can be changed.
  • The cost of each medicine.
  • Other medicines and supplements you are taking and how they may affect your treatment.

What are the costs of the medicines?

The wholesale prices of prescription antipsychotics are listed on the next page. Wholesale prices are the prices paid by pharmacies. These prices are given here so you can compare the costs of different medicines.

The cost to you for each medicine depends on your health insurance, the dose (amount) needed, and whether the medicine comes in generic form.

N/A = not available

Ask your doctor

  • What are your reasons for wanting me or someone I care for to take an antipsychotic or add one to treatment?
  • What other ways can we treat the condition without antipsychotics?
  • How long will it take for the medicine to start working?
  • What side effects should I watch for, and when should I call you about them?
  • How will we monitor my weight, cholesterol, and risk of diabetes?
  • Will an antipsychotic interfere with other medicines I am taking?
