Femalegra with kidney impairment: dosing and safety
Kidney function affects how the body clears Femalegra (Sildenafil Citrate) and many of its metabolites. For people with chronic kidney disease, dialysis, or even mild renal impairment from age or comorbidities, the standard 100mg dose may need adjustment. This page summarises the practical principles for Femalegra in renal impairment.
Why renal function matters for Femalegra
A meaningful fraction of Sildenafil Citrate or its active metabolites is cleared by the kidneys for many medications. Reduced eGFR slows clearance, raises plasma concentrations and prolongs effect. Sildenafil citrate inhibits PDE5, allowing cGMP to accumulate in vascular smooth muscle and increasing local blood flow during sexual arousal. The prescribing information for Sildenafil Citrate 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 Femalegra 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 Femalegra effects unpredictably and may warrant a temporary hold at 100mg.
Frequently asked questions
Is Femalegra safe with kidney problems? ▾
Mild to moderate kidney impairment usually allows Femalegra at adjusted lower 100mg 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 Femalegra if I have kidney disease? ▾
Yes — periodic eGFR and electrolyte monitoring is the standard practice for Femalegra in chronic kidney disease. Frequency depends on the severity of impairment and on Sildenafil Citrate-specific risks. The prescriber sets the schedule.
