What Is Fluoxetine (Prozac)?
Fluoxetine is an SSRI antidepressant that works by increasing serotonin levels in the brain. Serotonin is a neurotransmitter associated with mood regulation, emotional stability, and anxiety control.

The 10 mg dose is often used as a starting dose or for patients requiring lower-intensity treatment.
How Fluoxetine Works in the Brain
Fluoxetine works by blocking the reuptake of serotonin in the brain, increasing its availability in synaptic spaces.
Its main mechanisms include:
