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."[1]
Dosage
Acute agitation
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.[2] This is similar to 10 mg olanzepine intramuscularlly will make 87% of adults either tranquil or asleep at 15 minutes.[2]
Delirium
Haloperidol less than 3 mg per day can improve delirium.[3]
Dementia
Haloperidol 1 mg per day with gradual increase in dose might reduce the chance of extrapyramidal adverse drug reactions in patients treated for dementia.[4]
Availability
Haldol
Adverse effects
Dystonia
