Medications
Medications, when taken regularly as
prescribed, can help control bipolar mood swings. Although your family doctor
can prescribe medicines to treat
bipolar disorder, you will probably be referred to a
psychiatrist, who is trained specifically to treat
mental disorders.
Mood stabilizers, such as lithium, are usually
prescribed first to treat mania and to prevent the return of both manic and
depressive episodes. You may need to take a mood stabilizer for several years,
or even for the rest of your life, to manage the illness. Your doctor may
prescribe additional medicines—typically antipsychotics—to better control your
symptoms.
Your doctor will vary the amounts and combinations of
your medicines according to your symptoms, which
type
of bipolar disorder you have (bipolar I or II, rapid-cycling, or bipolar
with mixed symptoms), and how you respond to the medicines.
Medication Choices
Several medicines are used to treat bipolar disorder. It
may take time and several attempts at using different medicines to find the
treatment that works best for you. The most common medicines used to treat
bipolar disorder are:
- Mood stabilizers, such as
lithium carbonate (for example, Eskalith, Lithane, and
Lithobid). Experts believe lithium may affect certain brain chemicals (neurotransmitters) that cause mood changes, but how
the medicine works is not completely understood. A mood stabilizer and an
antipsychotic are recommended as the first medicines for acute manic episodes.
Anticonvulsants, such as valproate sodium (Depakene Syrup), divalproex
(Depakote), and carbamazepine (Tegretol and Equetro), are also considered mood
stabilizers. Valproate and divalproex are used to treat manic episodes. The
anticonvulsant lamotrigine (Lamictal) was approved for the long-term
maintenance treatment of bipolar I disorder and may be helpful for depression.
Anticonvulsants can be helpful in hard-to-treat bipolar episodes.
- Antipsychotics, such as olanzapine (Zyprexa),
risperidone (Risperdal), ziprasidone (Geodon), quetiapine (Seroquel), and
aripiprazole (Abilify). Antipsychotics improve
manic episodes. Olanzapine may be used in combination
with mood stabilizers and anticonvulsants.
- Benzodiazepines, such as diazepam (Valium). These may
be used instead of antipsychotics or as an additional medicine during a manic
phase.
What To Think About
Antidepressants,
such as fluoxetine (for example, Prozac), are used very carefully to treat
depression because they can trigger a
manic episode. Experts now recommend that
antidepressants only be used for short periods of time during severe episodes
of depression and that they be combined with mood stabilizers.10
If you are prescribed lithium carbonate,
valproate, or carbamazepine, you will need regular blood tests to monitor the
amount of medicine in your blood. Too much lithium in your bloodstream may lead
to serious
high lithium carbonate side effects. Your doctor may
want you to have blood tests while you are on medicine, to check whether the
medicine is affecting your liver, kidneys, and thyroid gland or to measure the
number of blood cells in your body.
During your doctor's
appointment, ask about:
- The side effects of each
medicine.
- How often you will need to take the
medicines.
- How the medicines may interact with other medicines you
are taking.
- Whether it's important that you take the medicines at
the same time every day.
Taking medicines during pregnancy for bipolar disorder
may increase the risk of birth defects. If you are pregnant, or thinking of
becoming pregnant, talk to your doctor. Medicines may need to be continued if
your bipolar disorder is severe. Your doctor can help weigh the risks of
treatment against the risk of harm to your pregnancy.
FDA
Advisories. The U.S. Food and Drug Administration (FDA) has
issued:
- An
advisory on antidepressant medicines and the risk of
suicide. The FDA does not recommend that people stop using these medicines.
Instead, a person taking antidepressants should be watched for
warning signs of suicide. This is especially important
at the beginning of treatment or when doses are changed.
- A warning
on anticonvulsants and the risk of suicide and suicidal thoughts. The FDA does
not recommend that people stop using these medicines. Instead, people who take
anticonvulsant medicine should be watched closely for
warning signs of suicide. People who take
anticonvulsant medicine and who are worried about this side effect should talk
to a doctor.
