Restoril with liver impairment: dosing and safety
The liver is the main site of metabolism for many medications including Restoril (Temazepam). Liver impairment slows clearance and can raise plasma levels of Temazepam above the intended range, amplifying side effects. People with chronic liver disease, recent hepatitis or significantly raised liver enzymes need a tailored approach to Restoril at 7.5mg, 15mg, 22.5mg, 30mg.
Why liver function matters
Temazepam undergoes hepatic metabolism through CYP enzymes for many medications. Reduced hepatic function slows this metabolism, prolongs the half-life and raises plasma concentrations. Temazepam binds the benzodiazepine site of the GABA-A receptor and allosterically enhances inhibitory chloride conductance. 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 Temazepam, baseline liver function tests are recommended before starting Restoril in any patient with risk factors and periodically during treatment in chronic liver disease. Severe impairment (Child-Pugh C) often contraindicates Restoril or requires substantial dose reduction; mild impairment usually permits standard 7.5mg, 15mg, 22.5mg, 30mg with closer monitoring.
Frequently asked questions
Is Restoril safe with liver problems? ▾
Mild liver impairment typically allows Restoril at standard or slightly reduced 7.5mg, 15mg, 22.5mg, 30mg with monitoring. Moderate-to-severe impairment often requires substantial dose reduction. Severe (Child-Pugh C) impairment may contraindicate Restoril entirely.
Will Restoril damage my liver? ▾
Most Sleep Aids and Hypnotics medications at standard 7.5mg, 15mg, 22.5mg, 30mg 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 Temazepam lists the documented risk.
