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.
People with bipolar disorder, depression, and other mood disorders often have episodes when they feel extremely sad, hopeless, anxious, or confused. When these emotions get too intense, the person may struggle with how to cope with overwhelming emotions, and for some people, efforts at coping with distress may take the form of acts of self-injury.
Self-injury, often including cutting, self-mutilation, or self-harm, is an injurious attempt to cope with overpowering negative emotions, such as extreme...
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.
Certain antipsychotic drugs cause significant weight gain and high cholesterol levels, and they may increase the risk of diabetes. People considering an antipsychotic for bipolar disorder should be screened for their risk of heart disease, stroke, and diabetes, according to a study published in Diabetes Care.
Common side effects of antipsychotic medications include:
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. Also, Geodon is linked to a rare but potentially fatal skin reaction.
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.
