What's the same
Microzide 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.
Key differences

Mechanism and action
Microzide: Hydrochlorothiazide blocks the sodium-chloride symporter in the distal convoluted tubule of the kidney, reducing sodium reabsorption and producing modest diuresis. Effexor: Effexor inhibits the reuptake of both serotonin and norepinephrine at the synapse.
When Microzide is preferred

When Effexor is preferred

No — they belong to different classes and have distinct side-effect profiles. Each medication has its own prescribing information.
