What the FDA labels say about taking them together
Clomipramine and sertraline
Clomipramine's FDA label of November 26, 2024 names sertraline in its drug interactions section; sertraline's label does not name clomipramine itself but warns about its class (Tricyclic antidepressants). The clomipramine label: “While all the selective serotonin reuptake inhibitors (SSRIs), e.g., fluoxetine, sertraline, paroxetine, and fluvoxamine, inhibit P450 2D6, they may vary in the extent of inhibition.”
