Preventation of severe nausea and vomiting. The neuroleptics (most commonly prochlor-perazine), are useful in treatment of drug induced nausea. Nausea arising from emotion should be treated with sedatives and antihistamines, rather than with these powerful drugs.

Other uses. The neuroleptic drugs may be used as tranquilizers to manage agitated and disruptive behavior. Neuroleptics are used in combination with narcotic analgetics for treatment of chronic pain with severe anxiety. Chlorpromazine is used to treat intractable hiccups. Droperidol is a component of neuroleptanesthesia. Prometathazine is not a good antipsychotic drug, but the agent is used in treating pruritus because of its antihistaminic properties.
