Antipsychotic medications are used as a short-term treatment for bipolar disorder to control psychotic symptoms such as hallucinations, delusions, or mania symptoms. These symptoms may occur during acute mania or severe depression. Some also treat bipolar depression, and several have demonstrated long-term value in preventing future episodes of mania or depression.
In people with bipolar disorder, antipsychotics are also used "off label" as sedatives, for insomnia, for anxiety, and/or for agitation. Often, they are taken with a mood-stabilizing drug and can decrease symptoms of mania until mood stabilizers take full effect. Some antipsychotic drugs may also help lessen bipolar depression.
Bipolar disorder is a serious diagnosis that affects more than 10 million Americans. Unlike depression, bipolar disorder is equally common in men and women. The onset of the condition typically occurs in the early 20s, but (although rare) the first symptoms can appear in early childhood or late in life.
Although some people may have only one episode, bipolar disorder is a lifelong condition that usually involves recurrent episodes. It's usually marked by episodes of mania or hypomania (low-grade...
Some antipsychotics seem to help stabilize moods on their own. As a result, they may be used alone as long-term treatment for people who don't tolerate or respond to lithium and anticonvulsants.
Antipsychotic drugs help regulate the functioning of brain circuits that control thinking, mood, and perception. It is not clear exactly how these drugs work, but they usually improve manic episodes quickly.
The newer antipsychotics usually act quickly and can help you avoid the reckless and impulsive behaviors associated with mania. More normal thinking often is restored within a few weeks.
Antipsychotics used to treat bipolar disorder include:
Common side effects of antipsychotic medications include:
Muscle spasms or tremors
Note: Clozaril is not used often, despite its effectiveness for bipolar disorder. The drug can cause a rare, potentially fatal side effect affecting the blood that requires weekly or biweekly blood test monitoring.
Older antipsychotic drugs are also generally not used to treat bipolar disorder, although they are less well-established for treating depressive symptoms or preventing episodes during long-term use. However, they may be helpful if a person has troublesome side effects or doesn't respond to the newer drugs. Older antipsychotics include Thorazine (chlorpromazine), Haldol (haloperidol), and Trilafon (perphenazine). These drugs may cause a serious long-term side effect called tardive dyskinesia, a movement disorder characterized by repetitive, involuntary movement like lip smacking, protruding the tongue, or grimacing. Newer atypical antipsychotics also have the potential to cause this side effect, but are thought to have a relatively lower risk than the older conventional antipsychotics.
