Used as a long-acting injectable antipsychotic for the treatment of schizophrenia and other psychotic disorders. It provides sustained release of haloperidol over several weeks, improving medication adherence in patients who may have difficulty with daily oral dosing. Commonly administered intramuscularly, it helps maintain stable drug levels, reducing the frequency of relapses and hospitalizations. It is typically reserved for patients who have responded well to oral haloperidol and require maintenance therapy.
