The use of depot neuroleptic haloperidol decanoate.

Twenty-nine patients were treated with haloperidol decanoate, the dosage ranging from 100 to 300 mg i.m. once a month, with duration of treatment ranging from 3-7 months. It seems that haloperidol decanoate could be useful in schizo-affective disorder/depressed type and also in manic disorder. The investigators were impressed by the relative lack of side effects.
