If you or a loved one has bipolar disorder, your doctor may have mentioned Thorazine to you as a possible medication option. Thorazine, generic name Chlorpromazine, is an antipsychotic drug that is prescribed for the treatment of bipolar disorder, as well as for schizophrenia and other disorders involving psychotic symptoms. In people with bipolar disorder, thorazine is often prescribed to treat the symptoms of mania, which include agitation, aggression, and impulsivity—as well as the symptoms of psychosis, such as grandiose delusions or paranoia.

 

Antipsychotic medications such as Thorazine, an older drug, as well as some of the newer antipsychotics, can be life-saving for people with bipolar disorder. For these people, the benefits of these drugs typically outweigh their risks.
