This page compares them: when each is used, how the mechanisms and indications differ, and whether the question "Sertraline vs Fluoxetine" makes sense to ask at all.
What is the relationship?
Sertraline and Fluoxetine are different things: Sertraline is a branded medication whose active ingredient is Sertraline (in the Anti-Depressants class), whereas Fluoxetine is in the Selective serotonin reuptake inhibitor (SSRI) class. They share a common therapeutic context and are sometimes weighed in the same clinical decision.
When Sertraline is used

When Fluoxetine is used
Fluoxetine is approved for major depressive disorder (adult and paediatric from age 8), obsessive-compulsive disorder, bulimia nervosa, panic disorder and premenstrual dysphoric disorder.
Mechanisms compared
Sertraline: Sertraline selectively blocks the serotonin transporter on the presynaptic neuron, preventing reuptake of serotonin from the synaptic cleft. Fluoxetine: Fluoxetine selectively inhibits the serotonin reuptake transporter, increasing synaptic serotonin availability.
When the comparison makes sense
Comparing Sertraline with Fluoxetine makes sense when both are in the same clinical decision: they belong to the same therapeutic class and may be considered as alternatives. If the question is between two options for the same need, the prescriber decides based on prior response, comorbidities and tolerance.
