What's the same
Vardenafil and Microzide 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
Vardenafil belongs to Erectile Dysfunction (ED) while Microzide belongs to Diuretics. 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
Vardenafil: The mechanism is identical to original Levitra: vardenafil selectively inhibits PDE5 in penile smooth muscle, allowing cyclic GMP produced during sexual arousal to accumulate. Microzide: Hydrochlorothiazide blocks the sodium-chloride symporter in the distal convoluted tubule of the kidney, reducing sodium reabsorption and producing modest diuresis.
When Vardenafil is preferred
Generic vardenafil shares the indication of the originator: erectile dysfunction in adult men.
When Microzide is preferred
Microzide is approved for hypertension (alone or in combination), oedema in heart failure, hepatic cirrhosis or nephrotic syndrome, and certain renal calcium-handling disorders.
Frequently asked questions

Can I switch from Vardenafil to Microzide? ▾
Switching between Vardenafil and Microzide is rarely an appropriate decision since they belong to different classes and treat different conditions. The real question is usually whether the diagnosis calls for one medication or the other — which the prescriber resolves.

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