In psychiatry, haloperidol is a "phenyl-piperidinyl-butyrophenone that is used primarily to treat schizophrenia and other psychoses. It is also used in schizoaffective disorder, delusional disorders, ballism, and Tourette syndrome (a drug of choice) and occasionally as adjunctive therapy in mental retardation and the chorea of Huntington disease. It is a potent antiemetic and is used in the treatment of intractable hiccups."
Haloperidol (10 mg) and promethazine (25 mg or 50 mg) intramuscular injection, combined in the same syringe will make 91% of adults either tranquil or asleep at 15 minutes. This is similar to 10 mg olanzapine intramuscularlly will make 87% of adults either tranquil or asleep at 15 minutes.
Haloperidol may cause acute dystonia. This is treated with either benztropine 1 to 4 mg intravenously or intramuscularly up to maximum 6 milligrams/day or diphenhydramine 25 to 50 mg intravenously over 2 minutes up to 100 milligrams/dose or 400 milligrams/day.
