Tibolone with kidney impairment: dosing and safety
Kidney function affects how the body clears Tibolone (Tibolone) and many of its metabolites. For people with chronic kidney disease, dialysis, or even mild renal impairment from age or comorbidities, the standard 2.5mg dose may need adjustment. This page summarises the practical principles for Tibolone in renal impairment.
Why renal function matters for Tibolone
A meaningful fraction of Tibolone or its active metabolites is cleared by the kidneys for many medications. Reduced eGFR slows clearance, raises plasma concentrations and prolongs effect. Tibolone is a prodrug; on absorption it is rapidly converted to three active metabolites (3α-OH-tibolone, 3β-OH-tibolone and Δ4-tibolone) with different tissue-selective activity. The prescribing information for Tibolone 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 Tibolone 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 Tibolone effects unpredictably and may warrant a temporary hold at 2.5mg.
Frequently asked questions
Is Tibolone safe with kidney problems? ▾
Mild to moderate kidney impairment usually allows Tibolone at adjusted lower 2.5mg 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 Tibolone if I have kidney disease? ▾
Yes — periodic eGFR and electrolyte monitoring is the standard practice for Tibolone in chronic kidney disease. Frequency depends on the severity of impairment and on Tibolone-specific risks. The prescriber sets the schedule.
