When to use

Bedside reminder of which drugs to reduce or avoid in liver disease and what to monitor. Not exhaustive — follow the product label.

How it works

No quantitative hepatic index like eGFR; grade by Child-Pugh (A/B/C) and reduce hepatically-cleared drugs in B/C.

Key points

  • Avoid hepatotoxins; monitor LFTs, bilirubin, INR and for encephalopathy.
  • Prefer oxazepam/lorazepam over long-acting benzodiazepines.
  • Statins are contraindicated in active liver disease; warfarin needs close INR monitoring.
  • Watch for hidden acetaminophen in combination products.
