Modern Medication Reference for Bipolar Disorder
Proper treatment of Bipolar Disorder can help to alleviate the emotional
highs and lows of the disorder. Because bipolar disorder is a recurrent illness,
it is recommended that the treatment plan be a long term plan. A strategy
that combines medication and cognitive behavioral therapy is optimal for
managing the disorder over time.
Bipolar Disorder is often much better controlled through continuous treatment.
Breaks in treatment can cause fluctuations in mood. Sometimes, even with
continuous treatment, there can be episodes of mania and depression. It is
important to report any emotional changes to a physician immediately. The
doctor may be able to prevent a full-blown episode by making adjustments
to the treatment plan. Working closely with the doctor and communicating
openly about treatment concerns and options can make a difference in treatment
effectiveness.
In addition, keeping a chart of daily mood symptoms, treatments, sleep patterns,
and life events may help people with bipolar disorder and their families
to better understand the illness. This chart also can help the doctor track
and treat the illness most effectively.
Bipolar Medications
Medications known as "mood stabilizers" usually are prescribed
to help control Bipolar Disorder. In general, people with Bipolar Disorder
continue treatment with mood stabilizers for extended periods of time (months
to years). Other medications are added when necessary, typically for shorter
periods, to treat episodes of mania or depression that break through despite
the mood stabilizer.
- Lithium, the first mood-stabilizing medication approved by the U.S. Food
and Drug Administration (FDA) for treatment of mania, is often
very effective in controlling mania and preventing the recurrence
of both manic and depressive episodes.
- Anticonvulsant medications, such
as valproate (Depakote®) or carbamazepine
(Tegretol®), also can have mood-stabilizing effects and may be especially
useful for difficult-to-treat bipolar episodes. Valproate was FDA-approved
in 1995 for treatment of mania.
- Newer anticonvulsant medications,
including lamotrigine (Lamictal®),
gabapentin (Neurontin®), and topiramate (Topamax®), are being studied
to determine how well they work in stabilizing mood cycles.
- Anticonvulsant
medications may be combined with lithium, or with each other, for
maximum effect.
Children and adolescents with bipolar disorder generally are treated with
lithium, but valproate and carbamazepine also are used. Researchers are evaluating
the safety and efficacy of these and other psychotropic medications in children
and adolescents. There is some evidence that valproate may lead to adverse
hormone changes in teenage girls and polycystic ovary syndrome in women who
began taking the medication before age 20. Therefore, young female patients
taking valproate should be monitored carefully by a physician.
Women with bipolar disorder who wish to conceive, or who become pregnant,
face special challenges due to the possible harmful effects of existing mood
stabilizing medications on the developing fetus and the nursing infant. Therefore,
the benefits and risks of all available treatment options should be discussed
with a clinician skilled in this area. New treatments with reduced risks
during pregnancy and lactation are under study.
Treatment of Bipolar Depression
Research has shown that people with bipolar disorder are at risk of switching
into mania or hypomania, or of developing rapid cycling, during treatment
with antidepressant medication. Therefore, "mood-stabilizing" medications
generally are required, alone or in combination with antidepressants, to
protect people with bipolar disorder from this switch. Lithium and valproate
are the most commonly used mood-stabilizing drugs today. However, research
studies continue to evaluate the potential mood-stabilizing effects of newer
medications.
- Atypical antipsychotic medications, including clozapine (Clozaril®),
olanzapine (Zyprexa®), risperidone (Risperdal®), quetiapine (Seroquel®),
and ziprasidone (Geodon®), are being studied as possible treatments
for bipolar disorder. Evidence suggests clozapine may be helpful
as a mood stabilizer for people who do not respond to lithium or anticonvulsants.
Other research has supported the efficacy of olanzapine for acute
mania, an indication that has recently received FDA approval. Olanzapine
may also help relieve psychotic depression.
- If insomnia is a problem,
a high-potency benzodiazepine medication such as clonazepam (Klonopin®) or lorazepam (Ativan®) may be helpful to
promote better sleep. However, since these medications may be habit-forming,
they are best prescribed on a short-term basis. Other types of sedative medications,
such as zolpidem (Ambien®), are sometimes used instead.
Changes to the treatment plan may be needed at various times during the
course of bipolar disorder to manage the illness most effectively. A psychiatrist
should guide any changes in type or dose of medication.
Be sure to tell the psychiatrist about all other prescription drugs, over-the-counter
medications, or natural supplements you may be taking. This is important
because certain medications and supplements taken together may cause adverse
reactions.
To reduce the chance of relapse or of developing a new episode, it is important
to stick to the treatment plan. Talk to your doctor if you have any concerns
about the medications.
Thyroid Function
People with bipolar disorder often have abnormal thyroid gland function.
Since too much or too little thyroid hormone alone can lead to mood and energy
changes, it is important that thyroid levels are carefully monitored by a
physician.
People with rapid cycling tend to have co-occurring thyroid problems and
may need to take thyroid pills in addition to their medications for bipolar
disorder. In addition, lithium treatment may cause low thyroid levels in
some people, resulting in the need to supplement the thyroid.
Medication Side Effects
Before starting a new medication for bipolar disorder, always talk with
your psychiatrist and/or pharmacist about possible side effects. Depending
on the medication, side effects may include weight gain, nausea, tremor,
reduced sexual drive or performance, anxiety, hair loss, movement problems,
or dry mouth. Be sure to tell the doctor about all side effects you notice
during treatment. He or she may be able to change the dose or offer a different
medication to relieve them. Your medication should not be changed or stopped
without the psychiatrist's guidance.
