From the Guidelines
Acetaminophen (Tylenol) at appropriate doses (no more than 2-3 grams per day in adults with liver disease) is generally considered the safest first-line analgesic for patients with liver disease, as it has a low risk of precipitating hepatic encephalopathy. For moderate pain, tramadol can be used with caution at reduced doses, not exceeding 50 mg within 12 hours, due to its increased bioavailability in patients with liver cirrhosis 1. In cases requiring stronger pain relief, certain opioids like fentanyl, hydromorphone, and oxycodone may be used at reduced doses with careful monitoring, as they have less hepatic metabolism than others 1.
It's essential to avoid NSAIDs (like ibuprofen, naproxen, and aspirin) in patients with cirrhosis or advanced liver disease, as these medications can impair renal function, cause fluid retention, and increase bleeding risk, potentially worsening hepatic encephalopathy 1. The safety of these medications relates to their metabolism pathways and effects on the compromised liver. Patients with liver disease often require lower doses, extended dosing intervals, and careful monitoring for signs of worsening encephalopathy when using any analgesic.
Some key points to consider when selecting analgesics for patients with liver disease include:
- Avoiding NSAIDs due to their potential to cause hepatotoxicity, nephrotoxicity, and decompensation in patients with liver cirrhosis 1
- Using acetaminophen at recommended doses, as it is generally considered safe for patients with liver disease 1
- Selecting opioids with less hepatic metabolism, such as fentanyl, hydromorphone, and oxycodone, and using them at reduced doses with careful monitoring 1
- Avoiding codeine and tramadol in patients with liver cirrhosis, or using them with caution at reduced doses, due to their potential to accumulate in the liver and cause side effects 1

From the Research
Analgesics with Low Risk of Precipitating Hepatic Encephalopathy
- Acetaminophen (paracetamol) is considered a safe analgesic for patients with liver disease, as it does not increase the risk of hepatotoxicity at recommended doses 2, 3, 4
- The use of acetaminophen is recommended at low doses (2-3 grams per day) for a short period, and it is a preferred analgesic due to its lack of platelet impairment, gastrointestinal toxicity, and nephrotoxicity associated with nonsteroidal anti-inflammatory drugs (NSAIDs) 2, 3, 4
- NSAIDs should be avoided in patients with severe hepatic impairment due to their direct hepatic toxicity and increased risk of life-threatening side effects 3, 4
- Opioids can precipitate or aggravate hepatic encephalopathy in patients with severe liver disease, and their use requires cautious administration and careful monitoring 3
- Certain opioids, such as fentanyl, sufentanil, and remifentanil, appear to have unaffected pharmacokinetics in hepatic disease, but their use still requires caution 3
Key Considerations
- Patients with liver disease require careful management of analgesics to avoid precipitating hepatic encephalopathy 3, 5
- The pharmacokinetics of analgesics are altered in patients with liver disease, and dose adjustments may be necessary to avoid toxicity 3, 4
- Monitoring of drug levels and careful observation of patients with liver disease are essential when using analgesics 5, 4
