There is some evidence that haloperidol is an effective treatment for  acute mania .
From the limited data available , there was no difference in overall efficacy of treatment between haloperidol and olanzapine or risperidone .
Some evidence suggests that haloperidol could be less effective than aripiprazole .
BACKGROUND The main objectives in treating mania are to control dangerous behaviour , reduce suicide , produce appropriate acute sedation and shorten the episode of mood disturbance .
Among different drugs , haloperidol has for many years been used in treating psychotic patients , but it has a troublesome side effect profile .
OBJECTIVES To assess the effects of haloperidol for the treatment of mania in comparison with placebo or other active drugs , either as monotherapy or add-on treatment .
A double-blind randomized clinical trial of rapid tranquilization with I.M. clonazepam and I.M. haloperidol in agitated psychotic patients with manic symptoms.
This double-blind clinical trial studied 16 acutely agitated psychotic patients with manic or manic-like symptoms who needed rapid tranquilization and were therefore on maintenance treatment . They were r and omized to receive intramuscular preparations of clonazepam ( 1 to 2 mg ) or haloperidol ( 5 to 10 mg ) at 0 , 0.5 , and 1.0 hours . Both medications produced significant reduction of manic symptoms within two hours of initial treatment ; however , haloperidol produced beneficial results more rapidly than clonazepam . All patients completed the study , with the exception of one haloperidol-treated patient who developed severe parkinsonism . It was concluded that I.M. clonazepam is an effective , safe , but slower-acting alternative to I.M. haloperidol in the treatment of agitated psychiatric patients in need of rapid tranquilization
