Addyi with liver impairment: dosing and safety
The liver is the main site of metabolism for many medications including Addyi (Flibanserin). Liver impairment slows clearance and can raise plasma levels of Flibanserin above the intended range, amplifying side effects. People with chronic liver disease, recent hepatitis or significantly raised liver enzymes need a tailored approach to Addyi at 100mg.
Why liver function matters
Flibanserin undergoes hepatic metabolism through CYP enzymes for many medications. Reduced hepatic function slows this metabolism, prolongs the half-life and raises plasma concentrations. Sexual desire is modulated by complex central nervous system pathways involving serotonin (generally inhibitory) and dopamine and norepinephrine (generally excitatory). The prescribing information typically classifies severity by Child-Pugh score (A mild, B moderate, C severe) and gives dose adjustments accordingly.
Practical guidance
According to the prescribing information for Flibanserin, baseline liver function tests are recommended before starting Addyi in any patient with risk factors and periodically during treatment in chronic liver disease. Severe impairment (Child-Pugh C) often contraindicates Addyi or requires substantial dose reduction; mild impairment usually permits standard 100mg with closer monitoring.
Frequently asked questions
Is Addyi safe with liver problems? ▾
Mild liver impairment typically allows Addyi at standard or slightly reduced 100mg with monitoring. Moderate-to-severe impairment often requires substantial dose reduction. Severe (Child-Pugh C) impairment may contraindicate Addyi entirely.
Will Addyi damage my liver? ▾
Most Women's Sexual Health medications at standard 100mg doses do not harm a healthy liver. A small subset can produce drug-induced liver injury in susceptible patients, usually detected by routine ALT/AST monitoring. The prescribing information for Flibanserin lists the documented risk.
