A man with cirrhosis and known portal hypertension presents for an initial consultation for mild to moderate chronic pain related to spinal stenosis. He does not take any pain medications and is able to perform all the activities of daily life. Which of the following is the MOST appropriate initial treatment for this patient?
A. Oxycodone 10 mg orally every 4 hours X
B. Ibuprofen 400 mg orally every 8 hours X
C. Acetaminophen 500 mg orally every 6 hours ✔

Many pain medications affect the hepatic and renal organ systems, complicating pain management in patients with severe liver disease. Acetaminophen is the preferred analgesic for mild to moderate pain in patients with cirrhosis due to the absence of the platelet impairment, gastrointestinal bleeding, and nephrotoxicity associated with nonsteroidal anti-inflammatory drugs (NSAIDs) (Table 1). The patient in the scenario has mild to moderate pain while retaining the ability to perform the normal activities of daily life. A stepwise approach starting with acetaminophen is the most appropriate approach in this scenario. Opioids are not appropriate as a first-line treatment for mild to moderate pain.

| Medication | Clinical Considerations |
| Acetaminophen | Preferred; avoid alcohol when taking |
| NSAIDs | Contraindicated in cirrhosis |
| Celecoxib | Acceptable for short-term use (<5 days) in Child–Pugh Class A; acceptable for Child–Pugh Class B for short term use with reduced dosages; not recommended for Child–Pugh Class C |
| Opioids | Immediate-acting formulations are acceptable for short-term use; avoid long-term use of opioids |
| Gabapentin and pregabalin | Considered safe in cirrhosis, but use with caution in patients with hepatic encephalopathy |
| Lidocaine and diclofenac | Topical formulations are considered safe in cirrhosis |
NSAIDs, nonsteroidal anti-inflammatory drugs.
The use of acetaminophen in patients with cirrhosis may seem paradoxical, given that acetaminophen is the leading cause of acute liver failure in the United States. However, the amount of acetaminophen shown to cause liver failure (>10 g/d) is typically much higher than the dosage recommended for general use (≤4 g/d). Acetaminophen undergoes metabolism by glucuronidation or sulfidation. A fraction can be converted into a highly reactive and toxic intermediate that requires further conjugation with glutathione. In large doses, the metabolic pathway is overwhelmed, and glutathione is depleted. In these circumstances, glutathione is no longer available to eliminate the toxic metabolites, leading to hepatic injury. Acetaminophen in doses of 2 g/d or less is not associated with impairment of the glutathione metabolic pathway and thus is not typically associated with worsening of a patient’s preexisting liver disease.
Splanchnic vasodilation associated with liver disease and portal hypertension may result in renal vasoconstriction, making patients with severe liver disease more susceptible to acute kidney injury, including hepatorenal syndrome. Acute kidney injury in the presence of liver failure has been associated with critically high mortality (as high as >50% 90-day mortality). NSAIDs have been associated with a higher risk of acute kidney injury and should be avoided in patients with severe liver disease.
