Vardenafil with kidney impairment: dosing and safety
Kidney function affects how the body clears Vardenafil (Vardenafil) and many of its metabolites. For people with chronic kidney disease, dialysis, or even mild renal impairment from age or comorbidities, the standard 5mg, 10mg, 20mg dose may need adjustment. This page summarises the practical principles for Vardenafil in renal impairment.
Why renal function matters for Vardenafil
A meaningful fraction of Vardenafil or its active metabolites is cleared by the kidneys for many medications. Reduced eGFR slows clearance, raises plasma concentrations and prolongs effect. Vardenafil selectively inhibits PDE5, the enzyme that breaks down cyclic guanosine monophosphate in the corpus cavernosum. The prescribing information for Vardenafil usually specifies dose adjustments by eGFR threshold (e.g. 30–60 vs <30 mL/min/1.73m²).
Practical guidance
According to the prescribing information, baseline kidney function should be checked before starting Vardenafil and periodically during treatment. People on dialysis need specialist input on dose timing relative to dialysis. Acute kidney injury — from dehydration, infection or other medications — can shift Vardenafil effects unpredictably and may warrant a temporary hold at 5mg, 10mg, 20mg.
Frequently asked questions
Is Vardenafil safe with kidney problems? ▾
Mild to moderate kidney impairment usually allows Vardenafil at adjusted lower 5mg, 10mg, 20mg doses with monitoring. Severe impairment (eGFR <30) often requires substantial reduction or alternative therapy. The prescriber decides based on lab results and the indication.
Do I need lab tests on Vardenafil if I have kidney disease? ▾
Yes — periodic eGFR and electrolyte monitoring is the standard practice for Vardenafil in chronic kidney disease. Frequency depends on the severity of impairment and on Vardenafil-specific risks. The prescriber sets the schedule.
