Prometrium with liver impairment: dosing and safety
The liver is the main site of metabolism for many medications including Prometrium (Progesterone). Liver impairment slows clearance and can raise plasma levels of Progesterone above the intended range, amplifying side effects. People with chronic liver disease, recent hepatitis or significantly raised liver enzymes need a tailored approach to Prometrium at 100mg, 200mg.
Why liver function matters
Progesterone undergoes hepatic metabolism through CYP enzymes for many medications. Reduced hepatic function slows this metabolism, prolongs the half-life and raises plasma concentrations. Progesterone in Prometrium binds to progesterone receptors and modulates gene expression in reproductive and other tissues. 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 Progesterone, baseline liver function tests are recommended before starting Prometrium in any patient with risk factors and periodically during treatment in chronic liver disease. Severe impairment (Child-Pugh C) often contraindicates Prometrium or requires substantial dose reduction; mild impairment usually permits standard 100mg, 200mg with closer monitoring.
Frequently asked questions
Is Prometrium safe with liver problems? ▾
Mild liver impairment typically allows Prometrium at standard or slightly reduced 100mg, 200mg with monitoring. Moderate-to-severe impairment often requires substantial dose reduction. Severe (Child-Pugh C) impairment may contraindicate Prometrium entirely.
Will Prometrium damage my liver? ▾
Most Hormones and Birth Control medications at standard 100mg, 200mg 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 Progesterone lists the documented risk.
