It may be used by mouth or injection into a muscle or a vein. Haloperidol typically works within 30 to 60 minutes. A long-acting formulation may be used as an injection every four weeks for people with schizophrenia or related illnesses, who either forget or refuse to take the medication by mouth.

Fluphenazine is given by mouth, intramuscularly, or just under the skin.

Triflupromazine (Vesprin) is an antipsychotic medication of the phenothiazine class. Among different effects of triflupromazine indication for use of this drug is severe emesis and severe hiccups. Due to its potential side effects (triflupromazine has higher risk for side effects than many other antipsychotics) it is not gold standard in antiemetic therapy.
