Key differences
Ozempic belongs to Diabetes Treatment while Prozac belongs to Anti-Depressants. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Ozempic: After subcutaneous injection, semaglutide is absorbed slowly and binds to the GLP-1 receptor in pancreatic beta cells, alpha cells, central nervous system and gut. Prozac: Fluoxetine selectively inhibits the serotonin reuptake transporter, increasing synaptic serotonin availability.
When Ozempic is preferred
The medication is indicated in adults with type 2 diabetes mellitus, alone or in combination with other antidiabetic agents, to improve glycaemic control.
When Prozac is preferred
Prozac is approved for major depressive disorder (adult and paediatric from age 8), obsessive-compulsive disorder (paediatric from age 7), bulimia nervosa, panic disorder and premenstrual dysphoric disorder.
