Description

Overview
Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) used to treat depression, anxiety disorders, obsessive-compulsive disorder (OCD), and other mood disorders. It is one of the most widely prescribed antidepressants and is known for its long half-life, which allows for flexible dosing.

Fluoxetine blocks the reuptake of serotonin in the brain, increasing serotonin levels in the synaptic cleft. This enhances mood regulation and helps alleviate symptoms of depression and anxiety.
