Fluphenazine, sold under the brand names Prolixin among others, is an antipsychotic medication.[1] It is used in the treatment of chronic psychoses such as schizophrenia,[1][2] and appears to be about equal in effectiveness to low-potency antipsychotics like chlorpromazine.[3] It is given by mouth, injection into a muscle, or just under the skin.[1] There is also a long acting injectable version that may last for up to four weeks.[1] Fluphenazine decanoate, the depot injection form of fluphenazine, should not be used by people with severe depression.[4]


Common side effects include movement problems, sleepiness, depression and increased weight.[1] Serious side effects may include neuroleptic malignant syndrome, low white blood cell levels, and the potentially permanent movement disorder tardive dyskinesia.[1] In older people with psychosis as a result of dementia it may increase the risk of dying.[1] It may also increase prolactin levels which may result in milk production, enlarged breasts in males, impotence, and the absence of menstrual periods.[1] It is unclear if it is safe for use in pregnancy.[1] Fluphenazine is a typical antipsychotic of the phenothiazine class.[1] Its mechanism of action is not entirely clear but believed to be related to its ability to block dopamine receptors.[1] In up to 40% of those on long term phenothiazines, liver function tests become mildly abnormal.[5]


Fluphenazine came into use in 1959.[6] The injectable form is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[7] It is available as a generic medication.[1] In the United States the tablets costs between 0.22 and 0.42 USD per day for a typical dose.[1] The wholesale cost in the developing world of the long acting form is between 0.20 and 6.20 USD per injection as of 2014.[8] It was discontinued in Australia around mid 2017.[9]



Effectiveness[edit]


A 2013 Cochrane review found that fluphenazine's was an imperfect treatment and other inexpensive drugs less associated with side effects may be an just as good in people with schizophrenia.[10]



Other animals[edit]


In horses, it is sometimes given by injection as an anxiety-relieving medication, though there are many negative common side effects and it is forbidden by many equestrian competition organizations.[11]
