Fluoxetine , sold under the brand name Prozac , among others, is an antidepressant medication of the selective serotonin reuptake inhibitor (SSRI) class[ 2] used for the treatment of major depressive disorder , anxiety , obsessive–compulsive disorder (OCD), panic disorder , premenstrual dysphoric disorder , and bulimia nervosa .[ 2] It is also approved for treatment of major depressive disorder in adolescents and children 8 years of age and over.[ 11] It has also been used to treat premature ejaculation .[ 2] Fluoxetine is taken by mouth .[ 2]
Common side effects include loss of appetite, nausea , diarrhea , headache , trouble sleeping , dry mouth , and sexual dysfunction. Serious side effects include serotonin syndrome , mania , seizures , an increased risk of suicidal behavior in people under 25 years old, and an increased risk of bleeding.[ 2] Antidepressant discontinuation syndrome is less likely to occur with fluoxetine than with other antidepressants, but it still happens in many cases. Fluoxetine taken during pregnancy is associated with a significant increase in congenital heart defects in newborns.[ 12] [ 13] It has been suggested that fluoxetine therapy may be continued during breastfeeding if it was used during pregnancy or if other antidepressants were ineffective.[ 14]
Fluoxetine was invented by Eli Lilly and Company in 1972 and entered medical use in 1986.[ 15] It is on the World Health Organization's List of Essential Medicines .[ 16] It is available as a generic medication .[ 2] In 2022, it was the 22nd most commonly prescribed medication in the United States, with more than 24 million prescriptions.[ 17] [ 18]
Eli Lilly also markets fluoxetine in a fixed-dose combination with olanzapine as olanzapine/fluoxetine (Symbyax), which was approved by the U.S. FDA for the treatment of depressive episodes of bipolar I disorder in 2003 and for treatment-resistant depression in 2009.[ 19] [ 20]
