Fluphenazine

Fluphenazine, sold under the brand names Prolixin among others, is an antipsychotic medication. It is used in the treatment of chronic psychoses such as schizophrenia, and appears to be about equal in effectiveness to low-potency antipsychotics. It is given by mouth, injection into a muscle, or just under the skin. There is a long acting injectable version that may last for up to four weeks.
