Viagra Professional with liver impairment: dosing and safety
The liver is the main site of metabolism for many medications including Viagra Professional (Sildenafil Citrate). Liver impairment slows clearance and can raise plasma levels of Sildenafil Citrate above the intended range, amplifying side effects. People with chronic liver disease, recent hepatitis or significantly raised liver enzymes need a tailored approach to Viagra Professional at 100mg.
Why liver function matters
Sildenafil Citrate undergoes hepatic metabolism through CYP enzymes for many medications. Reduced hepatic function slows this metabolism, prolongs the half-life and raises plasma concentrations. Sildenafil citrate inhibits PDE5, allowing the cyclic GMP produced during sexual arousal to accumulate in penile tissue, which relaxes the smooth muscle of the penile arteries and increases blood infl… 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 Sildenafil Citrate, baseline liver function tests are recommended before starting Viagra Professional in any patient with risk factors and periodically during treatment in chronic liver disease. Severe impairment (Child-Pugh C) often contraindicates Viagra Professional or requires substantial dose reduction; mild impairment usually permits standard 100mg with closer monitoring.
Frequently asked questions
Is Viagra Professional safe with liver problems? ▾
Mild liver impairment typically allows Viagra Professional at standard or slightly reduced 100mg with monitoring. Moderate-to-severe impairment often requires substantial dose reduction. Severe (Child-Pugh C) impairment may contraindicate Viagra Professional entirely.
Will Viagra Professional damage my liver? ▾
Most Erectile Dysfunction (ED) 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 Sildenafil Citrate lists the documented risk.
