What's the same
Clomiphene and Effexor are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.

Clomiphene belongs to Hormones and Birth Control while Effexor 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
Clomiphene: Clomiphene blocks estrogen receptors at the hypothalamus, preventing the negative feedback that estrogen normally exerts on gonadotropin-releasing hormone production. Effexor: Effexor inhibits the reuptake of both serotonin and norepinephrine at the synapse.
