Fluphenazine
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 per day for a typical dose.[1] The wholesale cost in the developing world of the long acting form is between US$0.20 and US$6.20 per injection as of 2014.[8] It was discontinued in Australia around mid 2017.[9]
