Fluphenazine is a typical antipsychotic drug used for the treatment of psychoses such as schizophrenia, manic phases of bipolar disorder, agitation, and dementia. It belongs to the piperazine class of phenothiazines. The medication may help control symptoms by blocking or lessening the effects of dopamine in the brain. It is not entirely known how the medication works. Dopamine may be elevated in people with schizophrenia or other psychoses. It also can be used as a calming drug in horses, though such use is illegal.

The medication was originally manufactured by Bristol-Myers Squibb. It is currently marketed under the brand name Modecate, a number of generic versions are also available. It is made by several different companies. The medication comes in oral liquid, tablets (1mg, 2.5mg, 5mg, 10mg), and injectable forms (including a short-acting and long-acting form).

Its side effect profile is similar to haloperidol, namely predominantly dopamine-blocking effects, which give rise to akathisia, parkinsonism, and tremor. Long term side effects include the potentially irreversible tardive dyskinesia and the potentially fatal neuroleptic malignant syndrome.
