Fluoxetine, a selective serotonin reuptake inhibitor (SSRI) most widely known by its brand name Prozac, was first approved by the FDA in 1987. It works by increasing the levels of serotonin in the brain, a neurotransmitter that helps maintain mental balance. While its primary and most famous use is for major depressive disorder (MDD), its applications have expanded significantly over the years.
FDA-Approved Uses of Fluoxetine
Beyond MDD, the U.S. Food and Drug Administration (FDA) has officially approved fluoxetine for several other conditions. These are known as 'on-label' uses, meaning they have undergone rigorous clinical trials to prove their safety and efficacy for these specific purposes.
Obsessive-Compulsive Disorder (OCD) Fluoxetine is effective for treating OCD in adults and children aged 7 and older. It helps reduce the anxiety associated with obsessions and compulsions by balancing serotonin levels.
Panic Disorder Fluoxetine is an approved treatment for individuals experiencing panic attacks. It helps reduce the frequency and intensity of attacks, as well as anticipatory anxiety.
Bulimia Nervosa Fluoxetine is the only antidepressant specifically FDA-approved for bulimia nervosa. Studies indicate that a specific daily amount is more effective than a placebo in reducing bingeing and vomiting episodes. It addresses behaviors, depressive symptoms, and eating attitudes.
Premenstrual Dysphoric Disorder (PMDD) Fluoxetine, sometimes marketed as Sarafem, is used to relieve the severe mood swings, irritability, and depression associated with PMDD. It can be taken daily or during the luteal phase of the menstrual cycle.
Treatment-Resistant Depression & Bipolar Depression (in Combination) Fluoxetine is approved for use in combination with olanzapine (Symbyax) to treat depressive episodes in Bipolar I Disorder and treatment-resistant depression.
Common Off-Label Uses
'Off-label' use is when a doctor prescribes medication for a non-FDA-approved condition. This is common and legal when based on clinical evidence and professional judgment.
Fluoxetine has several off-label applications including for anxiety disorders, PTSD, binge eating disorder, and body dysmorphic disorder. Other documented off-label uses exist for various conditions.
