Medicines
Medicine is the most effective treatment
for
schizophrenia, and there are many medicines that can
help. Medicines may be used for
positive or
negative symptoms, but they don't work as well for
negative symptoms as they do for positive symptoms.
- During a first psychotic episode or a
relapse, you probably will need constant care and may
have to go to a
hospital. If you already are using medicine, you may
need higher doses or other adjustments.
- When your symptoms are
better, you may need to continue to take medicines, sometimes in lower doses.
Talk to your doctor before making any changes in your medicines.
Using more than one medicine may be the best treatment for
schizophrenia, and there are many to choose from. But it may take time to find
which medicines are best for you. This may be frustrating. Getting support from
your family, your friends, and a community-based rehabilitation program is
helpful, especially while you and your doctor are trying to find the best
medicines. It also may help to speak with and get support from others who have
had trouble finding the right medicines.
Medicines sometimes have
severe side effects, so you and your doctor need to keep in touch about how
they are working and how you are feeling. If you feel a medicine isn't right
for you, your doctor can help you find a new one. Don't stop taking your
medicines without talking to your doctor.
Medicine choices
Medicines used most often to
treat schizophrenia include:
-
First-generation antipsychotics, such as haloperidol
(Haldol), perphenazine, and chlorpromazine. They are used to reduce
anxiety and agitation and to stop
delusions and
hallucinations. These medicines can work very well but
often have severe side effects, such as
tardive dyskinesia, which causes uncontrolled body
movements.
-
Second-generation antipsychotics, such
as risperidone (Risperdal), paliperidone (Invega), olanzapine (Zyprexa),
ziprasidone (Geodon), and quetiapine (Seroquel). These medicines effectively
treat symptoms of schizophrenia and may help reduce the risk of
relapse.
-
Clozapine, such as
Clozaril. This medicine is approved in the United States for treating severe
schizophrenia that has not improved with other treatment and for suicidal
behavior caused by schizophrenia. In the U.S., your doctor needs special
permission to prescribe clozapine for treating schizophrenia. You may need
checkups as often as once a week if you take clozapine.
The first-generation and second-generation antipsychotic
medicines both can help the symptoms of schizophrenia. Which medicine is best
for you usually depends on how well a medicine has worked in the past for you
and its side effects. Your doctor will help you find the best medicine for
you.
The following medicines often are used along with
antipsychotic medicines and clozapine:8
-
Lithium carbonate, such as Lithobid and
Eskalith. This medicine regulates moods. You will need your blood tested every
week when you first start taking it and every 6 or 12 months after you know the
correct dose. These tests check the levels of lithium carbonate in your blood,
because too much can be dangerous.
-
Antianxiety medicines, such as clonazepam (Klonopin)
and diazepam (for example, Valium). These medicines reduce anxiety and
nervousness.
-
Anticonvulsant medicines, such as
carbamazepine (for example, Tegretol) and valproate (for example, Depakote).
These medicines can keep your mood stable and reduce symptoms during a
relapse.
-
Antidepressant medicines, such as selective serotonin
reuptake inhibitors (SSRIs) (for example, Zoloft or Celexa) or tricyclic
antidepressants (for example, Pamelor). These medicines reduce symptoms of
depression that often occur along with
schizophrenia.
Side effects
Some side effects of antipsychotic
medicines can be serious.
-
Neuroleptic malignant syndrome is a rare but life-threatening side effect of antipsychotics.
The first signs usually include a fever between
102°F (38.9°C) and
103°F (39.4°C), a fast or
irregular heartbeat, rapid breathing, and severe sweating.
-
Tardive dyskinesia is body movement that you can't
control. Signs may include lip-smacking or continuous chewing, tongue-twitching
or thrusting the tongue out of the mouth, or quick and jerky movements (tics)
of the head.
Because of side
effects or the risk of side effects, you may be tempted to stop using your
medicine. But if you stop using medicine, the symptoms of schizophrenia may
come back or get worse.
If you have any concerns about side
effects, talk to your doctor. He or she will work with you. Your doctor may
give you a smaller dose of the antipsychotic medicine, have you try another
antipsychotic medicine, or give you another medicine to treat the side effect.
You may need regular blood tests to check for side effects when
you are taking medicines for schizophrenia. Children, teens, and older adults
may need to have blood tests more often than other people.
What to think about
If you stop taking your
medicines, you may have a relapse. Don't stop taking your medicines until you
talk with your doctor. If you and your health care team decide you should stop
using medicine, you will need to be checked on a regular basis.

Taking
medicines for
schizophrenia during pregnancy may make birth defects
more likely. If you are pregnant or thinking of becoming pregnant, talk to your
doctor. Your doctor can help you plan your pregnancy so that there will be as
little risk as possible to you and your baby.
Most people with
schizophrenia qualify for health care programs such as Medicare or Medicaid. To
find out whether you qualify, check with your local health and welfare agency.
