Which medication should be used cautiously because it can worsen hepatic encephalopathy?

• A. Acetaminophen
• B. Narcotics
• C. Antibiotics
• D. Benzodiazepines

Answer: (D)

In hepatic encephalopathy, the brain is especially sensitive to substances that depress the central nervous system because toxins that the liver should be filtering can accumulate and impair mental status. Benzodiazepines are strong CNS depressants, and in liver disease they are metabolized more slowly with active metabolites building up. This can dramatically increase sedation, confusion, and risk of coma, making these drugs particularly dangerous for someone with hepatic encephalopathy. Because of that, they should be avoided or used with extreme caution, and alternatives for anxiety or sleep should be considered. While narcotics can also cause sedation, they do not as reliably provoke hepatic encephalopathy as benzodiazepines, and antibiotics like rifaximin or those that reduce gut ammonia are used to treat the condition rather than worsen it.
