How It Works
These medicines balance certain brain
chemicals (neurotransmitters) that help regulate mood and control
symptoms of
bipolar disorder. They quickly improve
manic episodes.
Why It Is Used
Olanzapine
Olanzapine acts as a mood stabilizer.
It can help prevent the reckless and impulsive behaviors associated with mania
and may help treat the "losing touch with reality" that can occur with mania.
Olanzapine is often used in combination with other medicines (such as mood
stabilizers like lithium or valproate) to effectively treat the manic phase of
bipolar disorder.1
Risperidone
Risperidone can help restore more
normal thinking and a more normal mood. Preliminary studies show it to be
helpful when combined with other medicines (such as mood stabilizers) for
adults who experience “breakthrough” episodes of depression and mania (mood
disruption that occurs while taking maintenance medicines to control these
episodes).2 Risperidone may be effective in the
treatment of mania in young people, although research continues in this
area.
Quetiapine
Quetiapine is being studied for
effectiveness and safety for the treatment of mania associated with child and
teen bipolar disorder. Doctors have used quetiapine to treat the "losing touch
with reality" (psychosis) that is associated with
schizophrenia.
Ziprasidone
Ziprasidone has been used to treat
schizophrenia and was recently approved for the treatment of adult bipolar
disorder and mania. Research in children is limited, but preliminary studies
show ziprasidone may help reduce hypomania (a less severe form of mania),
hallucinations, aggression, irritability, depression, and insomnia. It may
cause less weight gain than other antipsychotic medicines.
Aripiprazole
Aripiprazole is a drug that is being
studied for its effectiveness in treating bipolar disorder, both on its own and
when combined with other medicines (such as mood stabilizers). It is also used
to treat schizophrenia.
How Well It Works
Olanzapine
Olanzapine has been shown to be safe
and effective in adults for the short-term treatment of acute mania due to
bipolar disorder.
Risperidone
Initial studies show risperidone is
effective and safe for treating mania in children and teens who have bipolar
disorder.3 Preliminary studies show risperidone to be
helpful when combined with other medicines (such as mood stabilizers) for those
who experience “breakthrough” episodes of depression and mania (mood disruption
that occurs while taking maintenance medicines to control these
episodes).2 Risperidone is often used successfully to
treat symptoms of
psychosis associated with bipolar disorder in
adults.
Quetiapine
Initial tests indicate that quetiapine
effectively reduces mania in adolescents with bipolar disorder when combined
with the mood stabilizer divalproex.4
Aripiprazole
Initial research shows that
aripiprazole works especially well in treating mania. It is also effective in
treating schizophrenia. Long-term studies on its safety and effectiveness are
still under way.
Side Effects
Olanzapine
Olanzapine can cause side effects
such as dry mouth, constipation, weight gain, drowsiness, increased appetite,
shakiness or tremors, slurred speech, low blood pressure that makes you feel
dizzy when you stand up, and sudden and sustained stiffness or muscle spasm
(dystonic reaction). Unusual side effects can include headaches or a skin rash
from an allergic reaction to the medicine.
Risperidone
Risperidone may cause sleepiness,
dystonic reaction, weight gain, menstrual irregularity, and breast tenderness.
Unusual side effects include an allergic reaction (skin rash), headaches,
constipation, decreased sexual desire and function, and increased heart
palpitations.
Quetiapine
Quetiapine can cause side effects such
as headaches, dizziness, rash, fever, weight gain, dry mouth, and other
flu-like symptoms.
Ziprasidone
Ziprasidone can cause side effects
such as tiredness, nausea, hard stools, dizziness, uncontrollable muscle
movements, diarrhea, rash, restlessness, and increased cough or runny nose. It
may also cause changes in transmission of electrical signals in the heart (EKG
abnormalities).
Aripiprazole
Aripiprazole can cause side effects
such as headache, anxiety, insomnia, nausea, vomiting, sleepiness or
drowsiness, lightheadedness, muscle twitching, restlessness, and
constipation.
Other side effects of antipsychotic medicines
Other possible side effects of antipsychotic medicines include:
- Blood sugar problems. The U.S. Food and Drug
Administration (FDA) requested that a warning be added to the prescribing
information for all atypical antipsychotics indicating an increased risk of
hyperglycemia (high blood sugar) and
type 2 diabetes for people taking these medicines. The
FDA recommends blood sugar monitoring of patients taking atypical
antipsychotics, especially those who are at risk for obesity or who have
diabetes or a family history of diabetes.
- Weight gain. But some
antipsychotic medicines appear less likely to cause weight gain. Talk to your
doctor if this is a concern.
- Hyperlipidemia (abnormalities in
cholesterol levels).
- Hyperprolactinemia, which is high levels of
certain hormones that can lead to breast enlargement in boys and girls and to
abnormal menstrual cycles in girls.
- Problems in children who have a
history of seizures or with conditions that make seizures more likely.
There are other extremely rare but serious side effects
that are possible with these medicines:
Neuroleptic malignant syndrome (NMS), which causes
life-threatening problems with your body's ability to regulate its temperature,
has been reported with antipsychotic medicines.
Tardive
dyskinesia (TD) is a drug-induced movement disorder that can cause
uncontrollable body movements. Newer medicines are much less likely than older
antipsychotics to cause the disorder.
Managing side effects
It may take several
attempts to find the right dose and medicine to treat your child's bipolar
symptoms. Effectiveness and side effects for each medicine vary from person to
person.
Some side effects are minor, and you can manage them
through lifestyle changes such as exercise, relaxation techniques, and diet
changes. Other side effects can be more serious and require changes to the dose
or type of medicine.

What To Think About
While these medicines have been
well studied for use in adults, there are few long-term studies that confirm
the effectiveness and safety of antipsychotics in children and teens who have
bipolar disorder. Be sure to use these medicines exactly as your doctor
prescribes them. If your child develops intolerable side effects to any of
these medicines, call your doctor immediately.
Before your child takes an antipsychotic medicine, be sure to tell your
doctor if your child has:
- A heart condition.
- A seizure
disorder.
- Problems with liver function.
- Problems with
blood pressure.
- Diabetes or high blood
sugar.
- Constipation.
- A history of breast
cancer.
- Problems with swallowing.
- Problems with
fainting.
Adolescents who could be pregnant or have had
neuroleptic malignant syndrome should not take these
medicines.
These medicines should be started in low doses. Talk
with your doctor about any other medicines your child may be taking to make
sure there are no negative drug interactions.
Your child may
require regular liver tests, blood tests, and blood pressure monitoring while
taking an antipsychotic medicine.
Avoid herbal stimulants (such as
ma huang, ginseng, or kola) while taking an antipsychotic medicine.
Talk to your doctor or pharmacist about drinking grapefruit juice while
you are taking an antipsychotic medicine. Grapefruit juice can increase the
level of these medicines in your blood. Having too much medicine in your blood
increases your chances of having serious side effects.
Newer
antipsychotics should be used with caution in people who drink alcohol or take
other medicines.
